Detailed Description

Single source of truth for every GPIO the turret uses.

Board: Freenove ESP32-WROVER CAM. With the camera attached only GPIO 0, 2, 12, 13, 14, 15, 32 and 33 are free, and the turret needs all eight. The static_asserts below turn a bad assignment into a build error instead of a board that corrupts PSRAM or refuses to boot.

constexpr

Initial value:

= {CAM_XCLK, CAM_SIOD, CAM_SIOC, CAM_Y9, CAM_Y8,    CAM_Y7,   CAM_Y6,
                              CAM_Y5,   CAM_Y4,   CAM_Y3,   CAM_Y2, CAM_VSYNC, CAM_HREF, CAM_PCLK}

TURRET

uint8_t pins::TURRET[]

constexpr

Initial value:

= {JOYSTICK_X,  JOYSTICK_Y,  JOYSTICK_SW, SERVO,
                              STEPPER_IN1, STEPPER_IN2, STEPPER_IN3, STEPPER_IN4}
