Also, we add a newline character ‘\n’ because that’s what the Arduino is expected to end its reading with Serial.readStringUntil(‘\n’). Then, we do the same thing as we did before: we read a line, decode it to string, and remove any trailing character. We’re not using the...
You can use the following statement to discard all data in the receive buffer: while(Serial.read() >= 0) ; // flush the receive buffer. Serial.write and Serial.print do not block. Older versions of Arduino would wait until all characters were sent before returning. Instead, characters ...
Adding hardware flow control isn't really an option as our product has been working fine up until this software upgrade. @Dave-Osborne - FIFO Overflow means that the internal ESP32 UART1 FIFO got full before the data could be read by the Arduino Sketch. One way to overcome it would be ...

I am using Arduino, I have a sketch that need to read Serial data, my sketch upload well to the ESP32 so i know my rx and tx pin and communications are ok. I set the baudrate in both the Arduino terminla to 115200 and in my program: Seri...

您可以使用Arduino IDE内置的串口监视器与Arduino板通信。点击工具栏上的串口监视器按钮,调用begin()函数(选择相同的波特率)。 Arduino Mega 有三个额外的串口:Serial 1使用19(RX)和18(TX),Serial 2使用17(RX)和16(TX),Serial3使用15(RX)和14(TX)。 若要使用这三个引脚与您的个人电脑通信,你需要一个额外...
