兆易创新GD32E230G8U6-GD32 ARM Cortex-M23 Microcontroller GigaDevice Semiconductor Inc. GD32E230xx ARM® Cortex®-M23 32-bit MCU Datasheet General description The GD32E230xx device belongs to the value line of GD32 MCU family. It is a new 32-bit general-purpose microcontroller based on the ARM® Cortex®-M23 core. The Cortex-M23 processor is an energy-efficient processor with a very low gate count. It is intended to be used for microcontroller and deeply embedded applications that require an area-optimized processor. The processor delivers high energy efficiency through a small but powerful instruction set and extensively optimized design, providing high-end processing hardware including a single-cycle multiplier and a 17-cycle divider. The GD32E230xx device incorporates the ARM® Cortex®-M23 32-bit processor core operating at up to 72 MHz frequency with Flash accesses 0~2 wait states to obtain maximum efficiency. It provides up to 64 KB embedded Flash memory and up to 8 KB SRAM memory. An extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer one 12-bit ADC and one comparator, up to five general 16-bit timers, a basic timer, a PWM advanced timer, as well as standard and advanced communication interfaces: up to two SPIs, two I2Cs, two USARTs, and an I2S. The device operates from a 1.8 to 3.6 V power supply and available in –40 to +85 °C temperature range. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications. The above features make the GD32E230xx devices suitable for a wide range of applications, especially in areas such as industrial control, motor drives, user interface, power monitor and alarm systems, consumer and handheld equipment, gaming and GPS, E-bike and so on.   Device information Table 2-1.

Up to 72 MHz operation frequency
Single-cycle multiplication and hardware divider
Ultra-low power, energy-efficient operation
Excellent code density
Integrated Nested Vectored Interrupt Controller (NVIC)
24-bit SysTick timer

The Cortex®-M23 processor is based on the ARMv8-M architecture and supports both Thumb and Thumb-2 instruction sets. Some system peripherals listed below are also provided by Cortex®-M23:
Internal Bus Matrix connected with AHB master, Serial Wire Debug Port and Single-cycle IO port
Nested Vectored Interrupt Controller (NVIC)
Breakpoint Unit(BPU)
Data Watchpoint and Trace (DWT)
Serial Wire Debug Port


Embedded memory

Up to 64 Kbytes of Flash memory
Up to 8 Kbytes of SRAM with hardware parity checking

64 Kbytes of inner Flash and 8 Kbytes of inner SRAM at most is available for storing programs and data, both accessed (R/W) at CPU clock speed with 0~2 wait states. Table 2-3. GD32E230xx memory map shows the memory map of the GD32E230xx series of devices, including code, SRAM, peripheral, and other pre-defined regions.

Clock, reset and supply management

Internal 8 MHz factory-trimmed RC and external 4 to 32 MHz crystal oscillator

Internal 28 MHz RC oscillator
Internal 40 KHz RC calibrated oscillator and external 32.768 KHz crystal oscillator
Integrated system clock PLL
1.8 to 3.6 V application supply and I/Os
Supply Supervisor: POR (Power On Reset), PDR (Power Down Reset), and low voltage detector (LVD)
The Clock Control Unit (CCU) provides a range of oscillator and clock functions. These include speed internal RC oscillator and external crystal oscillator, high speed and low speed two types. Several prescalers allow the frequency configuration of the AHB and two APB domains. The maximum frequency of the AHB, APB2 and APB1 domains is 72 MHz/72 MHz/72 MHz. See Figure 2-8. GD32E230xx clock tree for details on the clock tree.
The Reset Control Unit (RCU) controls three kinds of reset: system reset resets the processor core and peripheral IP components. Power-on reset (POR) and power-down reset (PDR) are always active, and ensures proper operation starting from 1.71 V and down to 1.67 V. The device remains in reset mode when VDD is below a specified threshold. The embedded low voltage detector (LVD) monitors the power supply, compares it to the voltage threshold and generates an interrupt as a warning message for leading the MCU into security.
Power supply schemes:
VDD range: 1.8 to 3.6 V, external power supply for I/Os and the internal regulator. Provided externally through VDD pins.
VSSA, VDDA range: 1.8 to 3.6 V, external analog power supplies for ADC, reset blocks, RCs and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively.
VBAK range: 1.8 to 3.6 V, power supply for RTC, external clock 32 KHz oscillator and backup registers (through power switch) when VDD is not present.

Boot modes

At startup, boot pins are used to select one of three boot options:
Boot from main Flash memory (default)
Boot from system memory
Boot from on-chip SRAM

In default condition, boot from main Flash memory is selected. The boot loader is located in the internal boot ROM memory (system memory). It is used to reprogram the Flash memory by using USART0 (PA9 and PA10) or USART1 (PA14 and PA15 or PA2 and PA3).

Power saving modes

The MCU supports three kinds of power saving modes to achieve even lower power consumption. They are sleep mode, deep-sleep mode, and standby mode. These operating modes reduce the power consumption and allow the application to achieve the best balance

between the CPU operating time, speed and power consumption.
Sleep mode
In sleep mode, only the clock of CPU core is off. All peripherals continue to operate and any interrupt/event can wake up the system.
Deep-sleep mode
In deep-sleep mode, all clocks in the 1.2V domain are off, and all of the high speed crystal oscillator (IRC8M, HXTAL) and PLL are disabled. Only the contents of SRAM and registers are retained. Any interrupt or wakeup event from EXTI lines can wake up the system from the deep-sleep mode including the 16 external lines, the RTC alarm, RTC tamper and timestamp, CMP output, LVD output and USART wakeup. When exiting the deep-sleep mode, the IRC8M is selected as the system clock.
Standby mode
In standby mode, the whole 1.2V domain is power off, the LDO is shut down, and all of IRC8M, HXTAL and PLL are disabled. The contents of SRAM and registers (except backup registers) are lost. There are four wakeup sources for the standby mode, including the external reset from NRST pin, the RTC alarm, the FWDGT reset, and the rising edge on WKUP pin.

Analog to digital converter (ADC)

12-bit SAR ADC's conversion rate is up to 2 MSPS
12-bit, 10-bit, 8-bit or 6-bit configurable resolution
Hardware oversampling ratio adjustable from 2 to 256x improves resolution to 16-bit
Input voltage range: VSSA to VDDA
Temperature sensor

One 12-bit 2 MSPS multi-channel ADC is integrated in the device. It has a total of 12 multiplexed channels: up to 10 external channels, 1 channel for internal temperature sensor (VSENSE) and 1 channel for internal reference voltage (VREFINT). The input voltage range is between VSSA and VDDA. An on-chip hardware oversampling scheme improves performance while off-loading the related computational burden from the CPU. An analog watchdog block can be used to detect the channels, which are required to remain within a specific threshold window. A configurable channel management block can be used to perform conversions in single, continuous, scan or discontinuous mode to support more advanced use.
The ADC can be triggered from the events generated by the general level 0 timers (TIMERx) and the advanced timer (TIMER0) with internal connection. The temperature sensor can be used to generate a voltage that varies linearly with temperature. It is internally connected to the ADC_IN16 input channel which is used to convert the sensor output voltage in a digital value.

DMA

5 channels DMA controller
Peripherals supported: Timers, ADC, SPIs, I2Cs, USARTs and I2S

The flexible general-purpose DMA controllers provide a hardware method of transferring data between peripherals and/or memory without intervention from the CPU, thereby freeing up bandwidth for other system functions. Three types of access method are supported: peripheral to memory, memory to peripheral, memory to memory.
Each channel is connected to fixed hardware DMA requests. The priorities of DMA channel requests are determined by software configuration and hardware channel number. Transfer size of source and destination are independent and configurable.

General-purpose inputs/outputs (GPIOs)

Up to 39 fast GPIOs, all mappable on 16 external interrupt lines
Analog input/output configurable
Alternate function input/output configurable

There are up to 39 general purpose I/O pins (GPIO) in GD32E230xx, named PA0 ~ PA15 and PB0 ~ PB15, PC13 ~ PC15, PF0 ~ PF1, PF6 ~ PF7 to implement logic input/output functions. Each of the GPIO ports has related control and configuration registers to satisfy the requirements of specific applications. The external interrupts on the GPIO pins of the device have related control and configuration registers in the Interrupt/event controller (EXTI). The GPIO ports are pin-shared with other alternative functions (AFs) to obtain maximum flexibility on the package pins. Each of the GPIO pins can be configured by software as output (push- pull open-drain or analog), as input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. All GPIOs are high-current capable except for analog inputs.

Timers and PWM generation

One 16-bit advanced timer (TIMER0), up to five 16-bit general timers (TIMER2, TIMER13
~ TIMER16), and one 16-bit basic timer (TIMER5)
Up to 4 independent channels of PWM, output compare or input capture for each general timer and external trigger input
16-bit, motor control PWM advanced timer with programmable dead-time generation for output match
Encoder interface controller with two inputs using quadrature decoder
24-bit SysTick timer down counter
2 watchdog timers (free watchdog timer and window watchdog timer)

The advanced timer (TIMER0) can be used as a three-phase PWM multiplexed on 6 channels.

It has complementary PWM outputs with programmable dead-time generation. It can also be used as a complete general timer. The 4 independent channels can be used for input capture, output compare, PWM generation (edge- or center- aligned counting modes) and single pulse mode output. If configured as a general 16-bit timer, it has the same functions as the TIMERx timer. It can be synchronized with external signals or to interconnect with other general timers together which have the same architecture and features.
The general timer can be used for a variety of purposes including general time, input signal pulse width measurement or output waveform generation such as a single pulse generation or PWM output, up to 4 independent channels for input capture/output compare. TIMER2 is based on a 16-bit auto-reload up/down counter and a 16-bit prescaler. TIMER13 ~ TIMER16 is based on a 16-bit auto-reload up counter and a 16-bit prescaler. The general timer also supports an encoder interface with two inputs using quadrature decoder.
The basic timer, known as TIMER5 can also be used as a simple 16-bit time base.

The GD32E230xx have two watchdog peripherals, free watchdog and window watchdog. They offer a combination of high safety level, flexibility of use and timing accuracy.
The free watchdog timer includes a 12-bit down-counting counter and an 8-bit prescaler. It is clocked from an independent 40 KHz internal RC and as it operates independently of the main clock, it can operate in deep-sleep and standby modes. It can be used either as a watchdog to reset the device when a problem occurs, or as a free-running timer for application timeout management.
The window watchdog is based on a 7-bit down counter that can be set as free-running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from the main clock. It has an early wakeup interrupt capability and the counter can be frozen in debug mode.
The SysTick timer is dedicated for OS, but could also be used as a standard down counter. The features are shown below:
A 24-bit down counter
Auto reload capability
Maskable system interrupt generation when the counter reaches 0
Programmable clock source


Real time clock (RTC)

Independent binary-coded decimal (BCD) format timer/counter with five 32-bit backup registers.
Calendar with subsecond, second, minute, hour, week day, date, year and month automatically correction
Alarm function with wake up from deep-sleep and standby mode capability
On-the-fly correction for synchronization with master clock. Digital calibration with 0.954 ppm resolution for compensation of quartz crystal inaccuracy.

The real time clock is an independent timer which provides a set of continuously running counters in backup registers to provide a real calendar function, and provides an alarm interrupt or an expected interrupt. It is not reset by a system or power reset, or when the device wakes up from standby mode. In the RTC unit, there are two prescalers used for implementing the calendar and other functions. One prescaler is a 7-bit asynchronous prescaler and the other is a 15-bit synchronous prescaler.

Inter-integrated circuit (I2C)

Up to two I2C bus interfaces can support both master and slave mode with a frequency up to 1 MHz (Fast mode plus)
Provide arbitration function, optional PEC (packet error checking) generation and checking

Supports SAM_V mode

C interface is an internal circuit allowing communication with an external I2C interface which is an industry standard two line serial interface used for connection to external hardware. These two serial lines are known as a serial data line (SDA) and a serial clock line (SCL). The I2C module provides different data transfer rates: up to 100 KHz in standard mode, up to 400 KHz in the fast mode and up to 1 MHz in the fast mode plus. The I2C module also has an arbitration detect function to prevent the situation where more than one master attempts to transmit data to the I2C bus at the same time. A CRC-8 calculator is also provided in I2C interface to perform packet error checking for I2C data.

Serial peripheral interface (SPI)

Up to two SPI interfaces with a frequency of up to 18 MHz

The SPI interface uses 4 pins, among which are the serial data input and output lines (MISO & MOSI), the clock line (SCK) and the slave select line (NSS). Both SPIs can be served by the DMA controller. The SPI interface may be used for a variety of purposes, including simplex synchronous transfers on two lines with a possible bidirectional data line or reliable communication using CRC checking. Specially, SPI1 has separate transmit and receive 32- bit FIFO with DMA capability and its data frame size can be 4 to 16 bits. Quad-SPI master mode is also supported in SPI1.

Universal synchronous asynchronous receiver transmitter (USART)
Up to two USARTs with operating frequency up to 4.5 MBits/s
Supports both asynchronous and clocked synchronous serial communication modes
IrDA SIR encoder and decoder support
LIN break generation and detection
ISO 7816-3 compliant smart card interface

The USART (USART0, USART1) are used to translate data between parallel and serial interfaces, provides a flexible full duplex data exchange using synchronous or asynchronous transfer. It is also commonly used for RS-232 standard communication. The USART includes a programmable baud rate generator which is capable of dividing the system clock to produce a dedicated clock for the USART transmitter and receiver. The USART also supports DMA function for high speed data communication.

Inter-IC sound (I2S)

One I2S bus Interfaces with sampling frequency from 8 KHz to 192 KHz, multiplexed with SPI0

uA级别智能门锁低功耗雷达模块让门锁更加智能省电节约功耗

uA级别智能门锁低功耗雷达模块让门锁更加智能省电节约功耗,指纹门锁并不是什么新鲜事,我相信每个人都很熟悉。随着近年来智能家居的逐步普及,指纹门锁也进入了成千上万的家庭。今天的功耗雷达模块指纹门锁不仅消除了繁琐的钥匙,而且还提供了各种智能功能,uA级别智能门锁低功耗雷达模块用在智能门锁上,可以实现门锁的智能感应屏幕,使电池寿命延长3-5倍,如与其他智能家居连接,成为智能场景的开关。所以今天的指纹门锁更被称为智能门锁。 今天,让我们来谈谈功耗雷达模块智能门锁的安全性。希望能让更多想知道智能门锁的朋友认识下。 指纹识别是智能门锁的核心 指纹识别技术在我们的智能手机上随处可见。从以前的实体指纹识别到屏幕下的指纹识别,可以说指纹识别技术已经相当成熟。指纹识别可以说是整个uA级低功耗雷达模块智能门锁的核心。 目前主要有三种常见的指纹识别方法,即光学指纹识别、半导体指纹识别和超声指纹识别。 光学指纹识别 让我们先谈谈光学指纹识别的原理实际上是光的反射。我们都知道指纹本身是不均匀的。当光照射到我们的指纹上时,它会反射,光接收器可以通过接收反射的光来绘制我们的指纹。就像激光雷达测绘一样。 光学指纹识别通常出现在打卡机上,手机上的屏幕指纹识别技术也使用光学指纹识别。今天的光学指纹识别已经达到了非常快的识别速度。 然而,光学指纹识别有一个缺点,即硬件上的活体识别无法实现,容易被指模破解。通常,活体识别是通过软件算法进行的。如果算法处理不当,很容易翻车。 此外,光学指纹识别也容易受到液体的影响,湿手解锁的成功率也会下降。 超声指纹识别 超声指纹识别也被称为射频指纹识别,其原理与光学类型相似,但超声波使用声波反射,实际上是声纳的缩小版本。因为使用声波,不要担心水折射会降低识别率,所以超声指纹识别可以湿手解锁。然而,超声指纹识别在防破解方面与光学类型一样,不能实现硬件,可以被指模破解,活体识别仍然依赖于算法。 半导体指纹识别 半导体指纹识别主要采用电容、电场(即我们所说的电感)、温度和压力原理来实现指纹图像的收集。当用户将手指放在前面时,皮肤形成电容阵列的极板,电容阵列的背面是绝缘极板。由于不同区域指纹的脊柱与谷物之间的距离也不同,因此每个单元的电容量随之变化,从而获得指纹图像。半导体指纹识别具有价格低、体积小、识别率高的优点,因此大多数uA级低功耗雷达模块智能门锁都采用了这种方案。半导体指纹识别的另一个功能是活体识别。传统的硅胶指模无法破解。 当然,这并不意味着半导体可以百分识别活体。所谓的半导体指纹识别活体检测不使用指纹活体体征。本质上,它取决于皮肤的材料特性,这意味着虽然传统的硅胶指模无法破解。 一般来说,无论哪种指纹识别,都有可能被破解,只是说破解的水平。然而,今天的指纹识别,无论是硬件生活识别还是算法生活识别,都相对成熟,很难破解。毕竟,都可以通过支付级别的认证,大大保证安全。 目前,市场上大多数智能门锁仍将保留钥匙孔。除了指纹解锁外,用户还可以用传统钥匙开门。留下钥匙孔的主要目的是在指纹识别故障或智能门锁耗尽时仍有开门的方法。但由于有钥匙孔,它表明它可以通过技术手段解锁。 目前市场上的锁等级可分为A、B、C三个等级,这三个等级主要是通过防暴开锁和防技术开锁的程度来区分的。A级锁要求技术解锁时间不少于1分钟,B级锁要求不少于5分钟。即使是高级别的C级锁也只要求技术解锁时间不少于10分钟。 也就是说,现在市场上大多数门锁,无论是什么级别,在专业的解锁大师面前都糊,只不过是时间长短。 安全是重要的,是否安全增加了人们对uA级别低功耗雷达模块智能门锁安全的担忧。事实上,现在到处都是摄像头,强大的人脸识别,以及移动支付的出现,使家庭现金减少,所有这些都使得入室盗窃的成本急剧上升,近年来各省市的入室盗窃几乎呈悬崖状下降。 换句话说,无论锁有多安全,无论锁有多难打开,都可能比在门口安装摄像头更具威慑力。 因此,担心uA级别低功耗雷达模块智能门锁是否不安全可能意义不大。毕竟,家里的防盗锁可能不安全。我们应该更加关注门锁能给我们带来多少便利。 我们要考虑的是智能门锁的兼容性和通用性。毕竟,智能门锁近年来才流行起来。大多数人在后期将普通机械门锁升级为智能门锁。因此,智能门锁能否与原门兼容是非常重要的。如果不兼容,发现无法安装是一件非常麻烦的事情。 uA级别低功耗雷达模块智能门锁主要是为了避免带钥匙的麻烦。因此,智能门锁的便利性尤为重要。便利性主要体现在指纹的识别率上。手指受伤导致指纹磨损或老年人指纹较浅。智能门锁能否识别是非常重要的。 当然,如果指纹真的失效,是否有其他解锁方案,如密码解锁或NFC解锁。还需要注意密码解锁是否有虚假密码等防窥镜措施。 当然,智能门锁的耐久性也是一个需要特别注意的地方。uA级别低功耗雷达模块智能门锁主要依靠内部电池供电,这就要求智能门锁的耐久性尽可能好,否则经常充电或更换电池会非常麻烦。

乐鑫WiFi模块代理商ESP32-S3彩屏旋钮屏温控器应用方案

发布时间: : 2022-05--24
乐鑫WiFi模块代理商ESP32-S3彩屏旋钮屏温控器应用方案,温控器用于控制室内暖通设备,通过暖通设备为室内环境提供冷源和热源,从而调节室内的温度环境,为人们提供舒适的生产生活环境。现有的温控器大多都是数字电子式的,但为了实现对温控器系统启停、温度的调节、预设用户的目标温度、调节温控器时间信息等功能,一般都设置有多个按钮或按键,如上调按键、下调按键、模式选择按键、开关按键等。一是操作复杂,二是外观确实不好看!为此特推出基于乐鑫WiFi模块代理商ESP32-S3应用旋钮彩屏的温控器方案。该智能温控器可以应用简单、优雅的外形结构,极大的降低用户的使用难度,提供智能化的控制方法,实现节能与舒适的平衡。 旋钮彩屏的温控器方案选择理由:ESP32-S3在彩屏应用接口方面及彩屏直驱尺寸都有一个很大的提升,支持SPI QSPI,MCU(8080)接口的屏,还支持RGB接口的彩屏,合适7寸以下常用规格的屏; 客户在选择彩屏时,可选性比较多!产品可实现多样化!还有一个重要的原因,ESP32-S3,可直接作为主控,同时还拥有WIFI、蓝牙; 性价比高,成本控制有很大的优势。 在彩屏应用方面 ,他可以实现较复杂的人机交互,双核,1.2GHZ,可引出丰富接口,开机速度快,媲美全志V3S,但价格却便宜不少,所以很多开发者为这颗芯片在摩拳擦掌。 将它用于旋钮屏温控器方案,也正是看中了他的性价比!他可以驱动10.1寸以下RGB、MIPI接口彩屏,同时也可以当串口屏应用; 内容显示支持图片、GIF,视频。 乐鑫WiFi模块代理商ESP32彩屏开发板推出,来源于技术团队朴素的理念:要让产品更有温度。“有温度”意味着需要关注人和产品的互动。 彩屏无疑是直观的可视化互动方式,推出的一款基于乐鑫ESP32芯片的彩屏开发板,用一颗“芯”让产品同时拥有WIFI、蓝牙通信功能,还同时驱动3.5寸彩屏及触屏。有了彩屏还不够,还要考虑时下年轻人需要的懒人模式-语音互动。所以技术团队在彩屏开发板上又集成了离线语音模块,让产品除了有温度,还更AI智能。彩屏、语音多种互动方式,瞬间拉近了人与机器的距离,让机器不再冰冷。所以自一款彩屏开发板上市以来,就得到了做86盒温控器、带屏开关等智能中控设备的厂商和ESP32开发者玩家的追捧。但这远远还没达到我们的目的,因为在我们日常生活中还会用到很多的家用电器,大到空调、热水器、抽烟机、运动健身器,小到电饭锅、料理机、养生壶等等这些每天必用的电器,我们更希望让枯燥的应用变的更有趣。 彩屏将成为新一代家电升级突破点,对于应用场景的打造,它着重于单品本身的能力,不是因为有了云和手机,更多的应该考虑如何实现小家电本身的升级,一定要从裸跑8位单片机时代升级到智能彩屏的嵌入式系统时代。 目前为了更好的配合家电厂商进行产品升级,基于乐鑫WiFi模块代理商ESP32芯片推出了高性价比的不同尺寸的彩屏开发板:1.54寸、2.4寸、2.8寸、3.5寸供选择应用。当然,如果你还有特殊的应用需求,可以告诉我们,我们资深的技术团队会为您的产品升级保驾护航!  支持跨系统的嵌入式软件开发平台,开发者通过鼠标拖拽方式替代传统界面编辑和逻辑代码编写,系统应用中,不需要像传统的操作方式进行环境搭建、原型搭建,此系统是开发环境免搭建,不仅降低开发设计人员的技术操作难度还大大缩短产品的开发周期。
