Table LED Matrix, Weeks of debugging, column problems

[mekohler]

I see what you're saying but I am at a complete loss right now

he Dlay loop is just the time delay until I move on to my next pattern/letter on the WHOLE table..in my real code it is modified to read the value off a pot so I can control the speed of patterns.

the i loop is to scan all 5 columns

the n loop is the delay between scans I believe...if I increase the n value then you can notice a flicker in the table as it scans...so If i program it to spell "Hi"...you can see the H flash on and off over and over, then it goes to I and flashes that on and off over and over...if n <259 there is no visible flashing/scanning...not even sure I need this loop!


That is all I have control over, and besides lowering/raising the n loop delay, I am not sure what I can do.

Well, I see that we both are not good at C, so why don't you drop it and use the PicBasic Pro that we all do here?

I am sorry but cannot help you more with the C program.

The tips at my last post I believe are enough to get your display bright enough at scan speed specified. But after that, the coding is another matter.
