=DEBUG LOG= SAM G53 Cannot Transmit Data to PC through EDBG UART

2018-05-09

A small bug that wastes me an afternoon and a whole night! EDBG is a embedded debug port that helps to debug or depoly the code. It has a virtual serial COM port that can support data communication between MCU and the host PC. I assume that this is known if you are going to read this post.

Use CH340-based USB Serial Converter on Linux in Python

2018-04-26

CH340 is a chip that convert USB data to serial data. Of cause the method discuss here can be applied to other USB-serial converter chips, such as PL2303 etc. It is helpful when you want to do serial communication with your circuit board. Usually I write Python scripts to interact with serial devices.
