-//SPI library (for ADC chip) uses the following pins, but we don't have to set them and inputs or outputs 
-// (this is done when the library is initialized, which is done by pre-instantiation:
-#define SCK_PIN   p7 //SPI Clock
-#define MISO_PIN  p6 //SPI input (data comming from DAC, here not connected) 
-#define MOSI_PIN  p5 //SPI output (data going to DAC)
-
-//**** CHIP SELECT pins for MP4922 DAC (mirrors and red laser)
-// VERY IMPORTANT: the chip select for the DACs should be different from the default SPI "SS" pin (Slave Select), which is 53 by default (and will be used by the Ethernet Shield). 
-#define CS_DAC_MIRRORS   p8 //Chip Select of the first DAC (mirrors)
-
-//**** LASERS pins:
-#define LASER_RED_PIN   p28 // NOT YET USED (TTL control). NOTE: this is NOT the locking sensing laser!
-#define LASER_GREEN_PIN p29 // USED (TTL control)
-#define LASER_BLUE_PIN  p30 // USED (TTL control)
-
-//**** MIRRORS: 
-//The DAC is 12 bytes capable (Max=4096), but we will limit this a little. 
-#define MAX_AD_MIRRORS 3845 // note: 4095 is the absolute maximum for the SPI voltage (5V). This is for checking hardware compliance, but max and min angles can be defined for X and Y in each LivingSpot instance.
-#define MIN_AD_MIRRORS 250  // note: 0 is 0 volts for the SPI voltage. 
-// We assume that the center of the mirror is at MAX_AD_MIRRORS/2 = 2000:
-#define CENTER_AD_MIRROR_X 2047 // This MUST BE the direction of the photodetector. 
-#define CENTER_AD_MIRROR_Y 2047 // This MUST BE the direction of the photodetector.
