问软件重新启动后ESP32在HardwareSerial初始化代码中的应用EN集成测试也叫组装测试，联合测试。是单元测试...
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 ...

The default pin location for serial(2) is fine, serial(1) needs to have its pins reassigned; as shown in the setup. Note the line to receive: if ( LIDARSerial.available() >= 1 ), I found that the Arduino DUE, STEM32, and ESP32 work better with a 1 instead of a 0. I send...
