// BOARD CONFIGURATION SELECTOR
// ============================================================================
// This file serves as a selector for different board configurations.
// Uncomment ONE of the board defines below to select your hardware setup.
//
// Available boards:
// - BOARD_FEATHER_TFT: Adafruit Feather RP2350 with 4.0" TFT ST7796
// - BOARD_PICO2_TFT: Raspberry Pi Pico 2 with 4.0" TFT ST7796
// - BOARD_PICO2_EINK: Raspberry Pi Pico 2 with E-Ink Display
//
// To switch boards: Simply uncomment one board and comment out the others.
// ============================================================================
// Forward declare display and touch types (actual enums in respective headers)
// Display options: DISPLAY_TYPE_ST7796, DISPLAY_TYPE_ST7789, DISPLAY_TYPE_EPAPER
// Touch options: TOUCH_TYPE_FT6336U, TOUCH_TYPE_NONE
