BR-6: Support #53

There is a teardown on YT showing the same PCB just with a graphics display. https://www.youtube.com/watch?v=fNMOmk37HbM. Looks to me like another display, but the rest might be standard. Any chance?

I have never worked with the STC8A8K64D4 MCU so I can't support it.

But I can give you some hints as to what would need to be done (general hints, not support):

This should make a nice project...

Thanks for the hints and the fast answer . I don't know this MCU neither and I a do only occasionally Arduino programs. Too bad. Nice device though. I have better chances to find the tube tick signal and add an Esp32 and write from scratch.Am 02.04.24, 02:20 schrieb Gissio @.***>:

Follow the traces from the microprocessor to the board's devices (keyboard, display, battery, etc) and see what port connects to what device. A multimeter might help. The 4-pin header is an SWD connector. Get a STLINK dongle, and attempt to download the firmware through it. Then use some disassembly tool to disassemble the firmware, and see how the code accesses the MCU internal devices (input/output ports, timers, ADCs, etc). Then, follow the steps in https://github.com/Gissio/radpro/blob/main/docs/developers.md and customize the code for the BR-6.
