• hidapi

  10 1,467 7.2 C

  A Simple cross-platform library for communicating with HID devices

  

Project mention: Trying to get raw HID working to get vim modes to trigger qmk events and layers. | /r/olkb | 2023-05-20

On the computer, write a program (the "host" or "server") that talks over the raw HID protocol. It is open ended how you do this, but IME both the Python pyhidapi and C hidapi were simple enough to get something started. The trickiest part might be getting the program to run with the permissions to talk the raw HID protocol (at least on Linux, there was some udev rule to set up). Read the documentation for these libraries for details about how to get set up.

• buck50

  3 538 0.0 C

  STM32F103 logic analyzer and more

Project mention: STM32F103C8T6 USART. HELP PLEASE IDK WHATS GOING ON | /r/embedded | 2023-07-11

From my experience, always check the hardware first. Are you wiring correctly, maybe your wire is too long. You should have a logic analyzer to debug these protocols. You can use another stm32 board as logic analyzer https://github.com/thanks4opensource/buck50 (there are lots of open source logic analyzers out there). If it shows dots, I guess your uart config is correct. Maybe your clock is wrong. Making a logic analyzer and watching the pulse will make it easier to debug further.
