Repo for STM32 based PION rearlight controller
Overview
The Pion backlight control board is engineered to manage a 7x109 pixel LED matrix backlight within automotive interiors. This board leverages the STM32H743VITx microcontroller for LED control, offering dynamic picture displaying.
- Main Processor: The STM32H743VITx microcontroller drives the control and processing of the LED matrix.
- CAN Transceivers:
- CAN Common: Handles standard communication for routine vehicle operations.
- CAN Critical: Dedicated line for critical or high-priority messages within the system.
- Power Regulation:
- 12V to 5V Regulator: Provides a 5V supply.
- 5V to 3.3V Regulator: Additional power regulation for the STM32.
- ESD Protection Circuit: Protects sensitive components from electrostatic discharge.
- GPIO Pins (4): Converted from 3.3V to 5V via a voltage regulator, ensuring compatibility with external systems operating at higher voltages.
