How to use

Open the demo folder by vscode. At the left lower corner of MAKEFILE TASKS:

• build: used for compiling, and generates .elf, .bin, etc, files in the output folder.
• flash: the .elf file in output folder will be flashed to atmega328p.
• debug: debug the program in assambly level. Refer to dwdebug for more information.

Auxiliary files in demo

DO NOT DELETE/MODIFY ANY OF THEM, otherwise the dwdebug.exe will not get the COM number automatically.

• serial.txt: store the outputs which produced by dwdebug.
• serial.bat: called by Makefile, it will analysis the serial.txt, and returns the COM number which used for dwdebug.
