Same chip on RK71

Hi, I have same chip BYK916 on my Rk71 keyboard, want to port QMK. Can i contribute with anything

Hey @gauravmanmode,

Since this project uses sdcc and targets a 8051 target, it's very unlikely that this will ever become a true QMK port. That said, I aim to implement core functionality like keyboard layouts as close as possible to QMK to make porting them easier.

If you want this firmware to work on your RK71 then an obvious way to help would be to go ahead and port it, although I would only recommend doing that if you:

• Have a full dump of the stock firmware, so that you can restore it if something goes wrong
  • https://github.com/gashtaan/sinowealth-8051-dumper
  • https://github.com/carlossless/sinowealth-kb-tool
• Have a tool to write firmware without the use of the ISP bootloader, since it's very easy to brick it
  • Any sinowealth programming tool, like the sinolink. It's what I own and use and you can find them easily on taobao or aliexpress
• Can analyze how your keyboard is wired up (continuity checks, building a partial schematic)

Also, I would ask to hold off trying to port anything until I fully implement usb functionality (most likely in around 2 weeks from now).

okay i will wait until you implement usb. also, do i need sinolink, is it really that brickable?

@gauravmanmode yes, it's extremely easy to lose the ability to launch into ISP. I wouldn't recommend working on this experimental firmware without a way to restore the original firmware.

@gauravmanmode I have pushed in working USB functionality, FYI

Amazing, you did it in such a few days. Thanks, I'm gonna try and make a port for RK71.
