This is a new edition of the motherboard from Logiteh G29 using EMC software

How to build own Logitech G29 Motherboard

What you need:

2x Bluepill (F103) or Blackpill (F103) or better F401 (for my board you can use even Arduino Leonardo, just change pins in src)
9x resistors 10K
9x tranzistors NPN (eg. BC546)
1x DC motor driver (eg. BTS7960B, CYTRON MD30C or cheaper some driver for couple Amps for couple $)
couple wires :)

Simple: (if you are using STM32 prefer to uplada a code via ST Link using ST Link Utility)

Upload the hex from the my repository to the one board controlling - EMC software.
Upload the hex from this repository to the my emulator board - G29emu.
Connect as it shown on the schematic respectively for F103 or F401.

To bulid a code just use the Arduino ide and paste a code from main.cpp and attach the libraries. You can use platform io too.

Simple presentation of the working system: https://youtu.be/wHjuSKlw6mE

In F103 version the Play Station button is centering the wheel, in F401 there is no option yet (1.07 software).
In F103 is a bug in software - EEPROM doesnt work properly, need to run software every reset / turn off the steering wheel to load the preset configs.

So in version 1.07 is working EEPROM but no centering button, but in version 1.06 is opposite.

For F401 you need to attach the pinout from connectors and my board in proper way - see in schematic from EMC Software.

The code and hex files are free. But the software have license for 10$, see: https://www.facebook.com/EMCDeveloper/

So the total build cost: boards about 5$ x 2 and software 10$ its equal to 20$.

For 2 x F103 version you only need to download:

For F103 and F401 version:

EMCUtility_1.07.exe
G29.png
EMCF401CCU6.hex
G29emu.bin
Schematic_F401C_v1.07.pdf (you need to check the pinout - is different than F103)
