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...

pin— Pin number character vector Pin number on the physical hardware, specified as a character vector. Example: D3 or A1. Note If you connect to ESP32 board and the pin's mode is set to AnalogInput, the pin number must always correspond to a digital pin. For details, see Pin-mapping...
