Using Lew's Duino Gear boards:
|
||
|
|
|
||
|
|
1. DNIN8 Input
|
||
|
|
This is a shift-register implementation of a digital input collector.
|
||
|
|
Multiple DNIN8 may be connected in sequence but it is IMPORTANT that the software
|
||
|
|
configuratuion correctly represents the number of boards connected otherwise the results will be meaningless.
|
||
|
|
|
||
|
|
Use in myAnimation.h
|
||
|
|
|
||
|
|
HAL(IO_DNIN8, firstVpin, numPins, clockPin, latchPin, dataPin)
|
||
|
|
|
||
|
|
e.g.
|
||
|
|
HAL(IO_DNIN8, 400, 16, 40, 42, 44)
|
||
|
|
This will create virtaul pins 400-415 using two DNIN8 boards connected in sequence.
|
||
|
|
Vpins 400-407 will be on the first board (closest to the CS) and 408-415 on the second.
|
||
|
|
|
||
|
|
Note: 16 pins uses two boards. You may specify a non-multiple-of-8 pins but this will be rounded up to a multiple of 8 and you must connect ONLY the number of boards that this takes.
|
||
|
|
|
||
|
|
This example uses Arduino GPIO pins 40,42,44 as these are conveniently side-by-side on a Mega which is easier when you are using a 3 strand cable.
