I'm having some issues with PWM-ing a rgb ledstrip.
I've bought the following ledstrip: http://www.ladyada.net/products/rgbledstrip/
(3 meters/30 leds p/m => 90 rgb leds => 270 leds)
I'd like to make my own RGB-led controller using RF to turn it on/off/change colors. This means I have to use VirtualWire. This takes up my timer1. So I only have 4 pwm pins left. I've tried some combinations, but somehow this always results in flickering leds when I turn them down to ~25%.
I've thought of buying the tlc5940. But if I'm correct, the library for the tlc5940 uses timer1 and timer2. So I can't use virtualwire in combination with tlc5940?
Now I've ordered https://www.sparkfun.com/products/10444
, but I'm not sure if this will solve my issue.
Can someone enlighten me on what my problem is here? Is it because I use 2 different timers to PWM the ledstrip? Or is it possibly the powersupply? Will the WS2801 solve my issue?
