Hello,
I noticed flicker with another code (for Microchip PIC).
I don't agree with you : " you'll end up jumping into a PWM cycle at random times "
but in the A6281 datasheet : " Latching new data into the brightness registers will not reset the PWM counter. "
Did somebody find a solution to reduce flickers ?
thank you
I've tested using three Shiftbrites with the sample code on an Arduino and also the bit bang route on a parallel port.
Always flickers on the arduino (slow or fast fading) and never flickers using the bit bang parallel interface.
Pulsing the enable does not seem to help at all.
Cannot seem to get it stable on the arduino.
Any ideas???
