opmerkingen:
|
||
|
|
-Alle instructies voor het display staan achterstevoren! (maakt
|
||
|
|
de code wat eenvoudiger)
|
||
|
|
-Zorg ervoor dat de delay-code ook wordt meegecompileerd, anders
|
||
|
|
gaat het hier mis...
|
||
|
|
-Deze code is gebaseerd op
|
||
|

"LCD routines for OLIMEX LPC-MT-2106,16x2 Character LCD 1602K,
