Hello, I'm controlling a 8x8 matrix with a 74HC595 (anode, line) and a TPIC6B595 (cathode, column). Thanks to the help of the forum this is working now! But it's too slow to display multiples LEDs at once by multiplexing them. I found that I should probably use the SPI protocol. Is there a good…

Using SPI with 74HC595 and TPIC6B595

There is no need to go to SPI, post your code and we can see how to speed it up.
You can mix C and C++ so that is not an issue.
