Dear list,
Did anyone else test the TLC5940 library with a TLC59401 chip? The chips seem very similar and I see people reporting success with the also similar TLC5941 chip.
I tried a few examples of the library and there seems to be no response at all. Looking with the scope when I run the basicUse sketch I see (negative) signals on the outpins with a frequency of 1 Khz (on and off) that do not look like PWM either. I use a 500Ω resistor on Iref.
Best, Hans.
