This is open source firmware for the JHEMCU's 8CH Receiver PWM PPM SBUS 32bit Encoder Signal Conversion Module.
Module is based on clone of STM32F031K6U6 so firmware can be easily ported to work on similar MCUs.
Precompiled binaries can be downloaded from releases page.
Platformio is used. Check https://docs.platformio.org/en/latest/core/quickstart.html for more info.
Flash precompiled binaries using STM32 ST-LINK Utility.
Note This module uses CSK32F031 clone MCU instead of authentic STM32F031 MCU. That might cause some failures during the process. Just disconnect and connect again if you face an error :) You might even need to replug the ST-Link during the process... Just proceed further.
Read and write protections must be disabled prio to programming.
That can be done choosing Target -> Erase Chip and/or setting options bytes:
Choose Target -> Program & Verify.... Browse a downloaded bin file and hit start button.
wiring:
| receiver | PWM Board |
|---|---|
| TX | SBUS |
| Vcc (*) | Vcc |
| GND | GND |
(*) Make sure you follow receiver's input voltage characteristic!
Special thanks to @arttuy for giving me the HW!
