// Filename: pins.h
// Description: GPIO pin definition header.
//
// Values >=40 are on expander board:
// 40-47 are GPA0-GPA7, 48-55 are GPB0-GPB8
//
// The expander board is controlled via I2C interface. PIN_LED_RED is a
// reserved controller pin to indicate errors in case the I2C controller
// malfunctions.
