When working withESP32 WiFi/Bluetooth MCUunderArduino SDK for ESP32, you will notice thatSerialwork just fine. ButSerial1andSerial2do not.ESP32has 3hardware serial portsthat can be mapped to almost any pin. But,Serial1andSerial2will not work. In case of ESP32 this just has to be done ...

是。 HardwareSerial库是c++编写的,应用于esp32 Arduino应用环境的串口驱动库,我们在安装好ESP32的Arduino开发环境后就已经集成了这个串口操作库，在实际应用时直接引用就可以了。

Hi, I'm trying to establish RS485 Modbus communication between ESP32 - RS485 Arduino driver board - Modbus device by using harwareserial(2) and the MODBUSMASTER library. https://github.com/4-20ma/ModbusMaster I know the MAXRS485 is TTL and ESP is CMOS, but I tried the code on an ...
https://github.com/espressif/arduino-es ... ard-pinmap Hello, sorry i have already been gone through this and it didn't work at all. Actually, I want to use GPS on UART1 serial port of ESP32 and when run the code sketch it didn't work at all on UART1 serial port and when I...
There are three hardware supported serial interfaces on the ESP32 known as UART0, UART1 and UART2. Like all peripherals, the pins for the UARTs can be logically mapped to any of the available pins on the ESP32. However, the UARTs can also have direct acc
