1  Using Arduino / LEDs and Multiplexing / Re: [solved/video] 8x8 RGB serial port with decent framerate (Colorduino) on: July 09, 2012, 01:10:50 am
Thanks Milamber! I've read through the forum that you had linked me. I'm still a bit confused as to why there is a columnLatch and a rowLatch in the shiftMatrixPWM.

I've got a 4x4 matrix with me which uses four 595s (one for each rgb colour and one for the common anode). This means I have a latch, clock and data pin that needs to be connected to the Arduino Uno. How should I connect it up using the shiftMatrixPWM? Or more specifically, what should I be assigning the rowLatch and columnLatch pins to?

Much appreciated.

Thanks! Just looking through the code, I'm confused why there is a row latch pin and also a column latch pin. My 4 shift registers for my 4x4 rgb matrix are currently daisy-chained and I can control each led... but am I meant I separate the latch pin for the common anodes from the latch pin for the cathodes for the shiftMatrixPWM to work?

I am curious as to how your project went in the end. Currently I'm trying to have a video feed on a 16x16 matrix...I think there's a long way ahead as I'm trying to get the shiftMatrixPWM working on my 4x4  smiley-roll .

Wow I'm working on something similar but have come across a problem: I am not quite sure how to use PWM with shift registers which are connected to my 8x8 rgb led matrix. I did some research and found Elco's shiftPWM library however I could not find the code for the shiftMatrixPWM library that everyone's talking about. Could you please let me know how you did it or specifically where I can find the shiftMatrixPWM code? Much appreciated.
