I am working on LED dot matrix produce by Sure Electronic which the board uses Holtek chip (HT1632). Does anyone know on how to develop program for this chip? Currently I am using PIC16F877A. I am not very familiar with PIC. I search for information on the net and most of them recommend SPI module.
Here is the code so far. I just want to light up any of the LED on the board. But it seems not working. I dont know whether the clock aint connect properly or due to program itself.
