B.4.8 Other Prototyping Board Modules
An optional LCD/keypad module is available that can be mounted on the Prototyping
Board. The signals on headers LCD1JB and LCD1JC will be available only if the LCD/
keypad module is installed. Refer to Appendix C, “LCD/Keypad Module,” for complete
information.
Rabbit’s SF1000 series serial flash may be installed in the socket labeled J11. The J11
interface is enabled in software by setting PD2 = 0. Header JP3 must have pins 2–3 jum-
pered when using the J11 interface. Note that the RabbitNet port and the J11 interface
cannot be used simultaneously.
B.4.9 Quadrature Decoder
Four quadrature decoder inputs are available on screw-terminal header J5. To use the PF0
input from the Rabbit microprocessor, which goes to the QD1B input, remember to recon-
figure the jumper on header JP3 to jumper pins 1–2.
Additional information on the use of the quadrature decoders on Parallel Port F is pro-
vided in the Rabbit 3000 Microprocessor User’s Manual.
B.4.10 Stepper-Motor Control
The Prototyping Board can be used to demonstrate the use of the RCM3305/RCM3315 to
control a stepper motor. Stepper motor control typically directs moves in two orthogonal
directions, and so two sets of stepper-motor control circuits are provided for via screw-
terminal headers J3 and J4.
In order to use the stepper-motor control, install two Texas Instruments L293DN chips at
locations U2 and U3 (shown in Figure B-10). These chips are readily available from your
favorite electronics parts source, and may be purchased through Rabbit’s
Web store
as part
number 660-0205.
