void HardwareSerial::begin(unsigned long baud, uint32_t config=SERIAL_8N1, int8_t rxPin=-1, int8_t txPin=-1, bool invert=false, unsigned long timeout_ms = 20000UL); 1. 使能串口,参数如下: baud:串口波特率,该值写0则会进入自动侦测波特率程序; config:串口参数,默认SERIAL_8N1为8位数据位...
esp32哪款支持网络云平台 esp32 softwareserial ESP-IDF SoftWare Serial 基于该项目 Github ArduinoEsp32-SoftwareSerial。 花了点时间写了一下软串口,因为娱乐和工程需要,所以我从过去自己在 Arduino 上实现的软串口移植到 ESP-IDF 下,为此也写一周了吧,使用硬件为 Bpi:Uno (esp32)。 更新了一次 esp8266 rtos...

For certain host machine setups, you must specify the port when you flash the board as in the following example. idf.py erase_flash flash monitor -p /dev/ttyUSB1 Build and Flash FreeRTOS with CMake Besides using theidf.pyscript provided by the IDF SDK to build and run your code, you...
example, an RTC-GPIO can be used for waking up the chip from Deep-sleep. 6 The GPIO pins support up to six digital functions, as shown in columns “Function 1~6” In Table IO_MUX. The function selection registers will be set as “N-1”, where Nis the function number. Below are ...
