#define glcdCSEL1 33 // CS1 Bit
#define glcdCSEL2 34 // CS2 Bit
#define glcdRW 35 // R/W Bit
#define glcdDI 36 // D/I Bit
#define glcdEN 37 // EN Bit
#define glcdData0Pin 22
#define glcdData1Pin 23
#define glcdData2Pin 24
#define glcdData3Pin 25
#define glcdData4Pin 26
#define glcdData5Pin 27
#define glcdData6Pin 28
#define glcdData7Pin 29
#define glcdRES 30 // Reset Bit
