HardwareSerial(0) is the same asSerialso be aware beginmethod accepts 4 parameters baud speed UART mode RX pin TX pin The real beauty of this solution is that almost any pin can be used as TX or RX pin for any serial port. MostESP32 dev boardshave labels like TX2 or RX2, but you...

在STM32duino III. - How to use Serial (USART)介绍了使用STM32多个串口的Arduino的基本程序。但是测试之后,其中使用HardwareSerial 声明串口的形式会出现编译错误。 在从0开始构建Arduino测试了Arduino缺省情况下串口的使用。它利用了USART1(分布在PA9,PA10)的使用情况。
