Black Pill Demo for USB-PD using an FUSB302
Note: This repository uses submodules!
This repository implements a simple demo app for the usb-pd library.
This will automatically select the maximum available output voltage from the charger as a demo.
Assumed wiring:
| STM32 pin | FUSB signal |
|---|---|
| B6 | SCL |
| B7 | SDA |
| B5 | IRQ |
| GND | GND |
Additionally the UART will output diagnostics messages on pin A9 at 1000000 baud 8N1.
For testing I'm using the reclaimer labs breakout boards. On these make sure to connect the pullup resistor power rails to vdd as well.
