STM32

Key pins

---

Key Pins	Description	Notes
A9	TX1	Connect to RX on the Serial port connector
A10	RX1	Connect to TX on the Serial port connector
B6	SCL1	OLED display
B7	SDA1	OLED display

Uploading code

---

If the code fails to upload, the error is usually one of the following:

1. The platformio.ini is missing the upload_protocol = serial and upload_port = COMX settings.
2. RX / TX pins have been mixed up from the STM to the serial port connector. They should go to the opposite pins on the serial port connector.
3. The jumper is not in the correct position.

Electrical Circuits

High-side driver H-Bridge

Wiring Check

1. Left Panel
2. Right Panel
3. Main Ground
4. 16V Rail
5. Control Panel Signal
6. Conntrol Panel Power
7. Potentiometer (FINISHED EDITING)

Tricks

1. Capacitors between power and ground prevent the bluepill from turning off when the H-bridges turn on. A 470uF capacitor keeps the bluepill powered at 3.3V for long enough when the voltage of the rest of the battery drops due to the sudden current draw of the h-bridges.
