# Firmware Pin Usage
This document summarizes the GPIOs used by the current firmware configuration.
The primary source of truth is `sdkconfig.defaults`; generated `sdkconfig`
differences are called out where they affect runtime behavior. Signal direction
is from the ESP32-S3 MCU perspective.

## Boot Hardware Test Profile
The current board profile enables `CONFIG_TQ_BOOT_TURNTABLE_CALIBRATION_ENABLE`.
After platform initialization, the stepper performs a bounded search for the
active-low KEY1/SW1 input on GPIO12. Serial logs report the configured motor
pins, the initial KEY1/SW1 state, switch detection, and the bounded no-switch
result before Wi-Fi bootstrap continues. After boot, the managed key-input task
keeps monitoring SW1 and logs its pressed, released, short-press, long-press,
and double-click events.

## Current Generated `sdkconfig` Difference
`sdkconfig.defaults` enables the key input task:
```text
CONFIG_TQ_KEY_INPUT_ENABLE=y
```
The current generated `sdkconfig` has it disabled:
```text
# CONFIG_TQ_KEY_INPUT_ENABLE is not set
```
This means the defaults describe the intended project pin usage, while the
current generated build configuration may not actively start the interrupt key
input task unless `sdkconfig` is regenerated or updated.
