For me this happened on a new 3dprinter Ender 3 - with the old printer the serial link worked fine but on the new one there was no output. This is not too good if you are setting up a new system as you won't know where the problem is. In fact the Ender3 used a different ...

Because of how they are designed, opening the USB serial port does not reset these boards. As a result, your sketch will begin sending data to the USB serial port faster than you can open the serial port. This means that if you have any serial output commands (Serial.print or Serial....
Serial.begin(9600); // start serial for output } void loop() { Wire.requestFrom(2, 6); // request 6 bytes from slave device #2 while(Wire.available()) // slave may send less than requested { char c = Wire.read(); // receive a byte as character ...
Just about all electronics use a UART serial port with RX and TX pins for debugging, bootloading, programming, serial output, etc. But it's rare for a computer to have a serial port anymore. Thus, a serial cable is an essential part of any electrical engineer's toolkit. This is a USB...
