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.

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.

A quick note. It includes installing packages and configuring the fresh system.

Evil-mode is an Emacs layer that allows editing using Vim. Therefore this is a also a cheat sheet for Vim itself.

A series of notes that I learn Emacs hacking. Spacemacs installation and some introduction to layers, a read list and some tips.

Fundamental of the LTE (long-term evolution) system, which is my note for a related video on Youtube. This is the third part. Heterogeneous network (small cell and relay node), coordinated multipoint, throughput calculation.
