What are the reasons why data cannot be received when using the serial port debugging assistant? Today, the editor will share with you the reasons why data cannot be received when using the serial port debugging assistant. If you are in need, please learn with the editor.
1. It may be that the various options of the serial port debugging assistant and the communication protocol (baud rate, etc.) settings are inappropriate and need to be changed again to ensure that the PC can sample correctly.
2. It may be that the input waveform is incorrect.
3. The physical connection may be incorrect;
4. The microcontroller cannot work normally;
5. The communication parameters may be incorrect;
6. The BAUD factor of the microcontroller is not adjusted well, because the BAUD of the PC is relatively accurate, but the microcontroller is not accurate and is prone to bit errors.
