 ### GPIO Pin Mapping
 
-The firmware controls 11 GPIO pins through memory-mapped registers. Each bit in the 16-bit GPIO registers corresponds to one pin:
-
-**GPIOA pins**: PA2, PA3, PA4, PA5, PA6, PA7, PA8, PA11, PA12 (bits 0-8)
-**GPIOC pins**: PC14, PC15 (bits 9-10)

 ### Deck configuration
 
-The configuration can be written using the [cfcli](https://github.com/evoggy/cfcli) tool. First create
-the desired configuration YAML file:
-
-```yaml
-version_major: 0
-version_minor: 1
-vid: 0xBC
-pid: 0x13
-rev: 'B'
-name: 'HP LED'
-partitions: []
-```

-Then use cfcli tool to flash the configuration via SWD:
