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.
Z-World’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 can-
not be used simultaneously.
B.4.9 Quadrature Encoder
Four quadrature encoder outputs are available on screw-terminal header J5. To use the
PF0 output from the Rabbit microprocessor, which goes to the QD1B output, remember to
reconfigure the jumper on header JP3 to jumper pins 1–2.
Additional information on the use of the quadrature encoders 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 RCM3360/RCM3370 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 Z-World’s Web store as
Z-World part number 660-0205.
