I assume you should use other pins for your FPS than 4 and 5 as these pins might be used for I2C already
#define PIN_WIRE_SDA (4)
#define PIN_WIRE_SCL (5)
static const uint8_t SDA = PIN_WIRE_SDA;
static const uint8_t SCL = PIN_WIRE_SCL;P.S.: please post your code in code tags, like described in the Forum How to:
