1）Arduino IDE 首先，我们需要在电脑上安装Arduino IDE，这个直接在Software | Arduino下载即可，目前最新版本是Arduino IDE 2.3.2，推荐稳定版本Arduino IDE 1.8.19。Arduino IDE 2）Arduino STM32 接下来，需要下载与所选开发板相对应的STM32核心库，这些库文件包含了STM32芯片的驱动程序和Arduino API的扩展，...

digitalWriteFast(digitalPinToPinName(ulPin), ulVal); 这个函数从来没见过,他的内部是怎么实现的?跳转进去看看,里面居然还是一个函数: digital_io_write(get_GPIO_Port(STM_PORT(pn)), STM_LL_GPIO_PIN(pn), ulVal); 还是个没见过的函数,再跳进去看看,内容如下: if (val) { LL_GPIO_SetOutputPin(port...
Don’t draw more than 20 milliamps (mA) of current from your Arduino’s GPIO pins, otherwise you may damage it. Such a small current can easily switch on a transistor, and the transistor could in turn switch on a motor, relay (this is another switch controlled by a small current, ...
board.digital_write(LED_PIN, state) try: while True: cmd = input("Enter command (1: ON, 0: OFF): ") if cmd == '1': toggle_led(1) elif cmd == '0': toggle_led(0) except KeyboardInterrupt: board.shutdown() Firmata的主要优势在于不需要频繁地重新编写和上传Arduino代码,可以通过Python...

数字I/O口 Digital IOArduino 引脚号直接对应ESP8266 GPIO 引脚。pinMode,digitalRead,和 digitalWrite 函数照常使用,所以读取GPIO2引脚,这样写:digitalRead(2) 。数字引脚 0~15可以设置为 INPUT,OUTPUT 或者 INPUT_PULLUP 模式。引脚 16可以设置为INPUT,OUTPUT 或者 INPUT_PULLDOWN_16 模式。在启动时,引脚被配置为...
Pin numbers in Arduino correspond directly to the ESP8266 GPIO pin numbers.pinMode,digitalRead, anddigitalWritefunctions work as usual, so to read GPIO2, calldigitalRead(2). Digital pins 0—15 can beINPUT,OUTPUT, orINPUT_PULLUP. Pin 16 can beINPUT,OUTPUTorINPUT_PULLDOWN_16. At startup, ...
