just before i get to the nitty gritty, just as an explanation of why, a little while ago i bought a LED matrix off ebay, with the driver board, thinking it would work alright with the bi-color matrix i got, at first when i hooked it upto the driver board i thought all was well and it would run fine, till i found out that the driver board is not equipped to handle this bi-color matrix so it made it bubcus, and the seller refused to help or comment about it.
so it had been sitting in my drawer for a while till i had a thought "i wonder if i can control it with my arduino", so i have come here to ask for advice before proceeding.
the board has Four HT1632C chips on it, and what looks to be Two 74HC1640's, ive included a picture, the larger square chips are the HT1632C's, and the 2 small ones are the 74HC1640's (if my eyes serve me correctly):
the current Pin markings are as follows:
8: GND (will this be needed if using a separate power source?)
11, 13, 15: GND (or this?)
12, 14, 16: +5v (or this?)
i have 2 arduinos, a mega 2560 and a UNO, im guessing either one of these will be fine, im not quite sure how to proceed with getting the arduino to pump data/commands into the board to display something like, scrolling text, or a clock ect, nor am i sure of which pin's from the display board to plug into what on the arduino as i am not familiar with the HT1632C's, any help or guidance, or even some more light shed on this would be great and will be many 1000's of thank you's.
