BR-6: Support

[StrandedAlien]

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):

• 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 an 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.

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 ***@***.***>: I have never worked with the STC8A8K64D4 MCU so I can't support it.
