etc ...

Demo code or from WCH MCU webpage - https://bitbucket.org/e_dragon/wch/src/master/
CN here - http://www.wch.cn/bbs/thread-65023-1.html
Unzip standard demo file.
Find header file in example
Keil project file in example too
Use any standard 8051 IC, such as AT89C51/AT89S51
Memory space select according to MCU config, avoid bootloader area, since out factory is already have bootloader.
Only download hex or bin into MCU

 * Use WCHISPTOOL
 * Short connect DOWN (or PROG) and 3.3V, plug in USB into download mode.
