TLC59711 refresh

by mvonrose on Tue Apr 13, 2021 7:15 pm

I'm driving some TLC59711 off of a Raspberry Pi 4 SPI bus. I'm having some problems getting smooth fades with multiple boards. It seems as you chain more boards together the time between refresh becomes REALLY slow. Is there something that I can do to increase the speed of the boards processing an input string?

This sounds like a DMX lighting type application is that what you have setup?

Are you using hardware or software SPI?

I realized the problem that the update function was getting called at each light update. With 20 of these boards linked it got WAY slowed down. So I took auto update off and just updated after setting all 240 lights.
