v4.1 version left part issue #244

Closed vadimkorzik closed 3 months ago

vadimkorzik commented 3 months ago

hello @foostan Thanks for the great project. I am facing a problem. I have assembled two sets of the keyboard version 4.1 and both have the same problem with the left part. it is correctly recognized as a drive to write a firmware but doesn't work correctly as a keyboard. Windows says "USB device not recognized". Both right parts work fine. The left part connected to the right via trrs doesn't work either. Looks like it is a software issue as it starts showing some info on oled but after a second "hangs" and does not respond to key presses. Flashed via firmware supplied and tried to build it myself with via and default km. Really appreciate your help.

Both right parts work fine.

If it’s correct, I think the software is no problem.

oled

Do you use OLED with Corne v4? I don’t confirm the OLED so please try to use without OLED.

I'm not going to use oled, just connected it to confirm that rp2040 is doing something (there is a code in firmware to print key presses to screen). on the right part oled is working fine

It is possible to write firmware, right? After writing the firmware, it doesn't get recognized as a keyboard. I'm using the same data and it works fine.

hi. turns out it was most likely my fault, i reflowed chips on both plates and they work now. looks like i overheated rp2040 while soldering.
