    2.3.3 Connect Power When all other connections have been made, you can connect power to the BL1810. Hook up the connector from the wall transformer to header J1 on the BL1810 as shown in Figure 3. The orientation of this connector is not important since the VIN (positive) volt- age is the middle pin, and GND is available on both ends of the three-pin header J1.

    This function initializes the digital outputs and sets up the driver for the analog input/outputs. The digital outputs correspond to the Rabbit processor’s port E bits 0–3, and the analog I/O uses timer B; bits 1, 2, and 4 of port D; and bits 6 and 7 of port E.
  • Page 39 void digOut(int channel, int value); sets the state of a digital output bit. jrioInit must be called first. channel is the output channel number (0-3 on the BL1810). value is the output value (0 or 1). void digOn(int channel); sets the state of a digital output bit to on (1). jrioInit must be called first.

Parallel Ports D and E on the Rabbit 2000 are double-buffered to provide precisely timed updating of the output pins. Each port is divided into an upper and a lower nibble. All bits of each nibble must be updated simultaneously.
