Hello!!! I´m trying to build a 5x8 RGB led matrix. I intended to drive 5 rgb leds rows with a ATmega328 and two 4051 multiplexers. And multiplex the 8 columns with a 4051 connected to an Attiny 85. Wich would be an i2c slave of the mega.
I tested the 4051 analog multiplexing and I can´t make it work as I intend. I attach the wiring of only one led and the code I´m testing.
Searching a bit I found that the TLC5940 would be a better choice. But it´s not easy to find in my country. I´d have to have it sent from China.
Thank you in advance.
