The Leynew TC420 Programmable LED controller is sold under many different names. Recognized under Linux as:

  1. The controller has it own TC420 hardware fan page how-ever support for Linux is lacking it seems.
  2. The windows software program is called PLed, for those without CD-ROM drive, I have attached the CD-ROM content.
  3. The PLed program can be started using Wine, how-ever the HID device does not get detected.

Since reverse-engineering a Windows Program for it's HID calls seems quite some work I will to see if I can flash my own software on the unit. It is running a STM32F103C8T6 chip.

I ordered an ST-LINKv2 programmer and development board, so hopefully I can start to program the chip 'soonish' via STLINK.

To be continued...
