Hi I am trying to replicate this just using the 74HC595. i have it working perfectly with one 8x8 module. My issue is I have added additional 8x8 Modules but the i cannot get it to output the the additional modules using this code. It just outputs to the first module over and over. i have changed the Bitmap array to reflect the additional modules but nothing has changed. Can someone help me as i am completely stuck.
Cheers
Chris
