PWM controllers

Started by larzyharzy February 28, 2005

I want to control the color of four light boxes depending on different sensor input. I want
each box to be able to go through the whole color spectrum independently of each other.

I imagine having 4 full color LED clusters - so I would need 12 PWM outputs in total.

I imagine having a BX24 for the sensor input and then have one or more PWM controllers
to control the LEDs.

Does this sound like a reasonable way to set it up? Can anyone recommend a good PWM

I saw that Atmel have two units AT90PWM2 and AT90PWM3 with up to 10 PWM outputs
Has anyone tried this controller?

I found this project that uses the AthenaHS PWM unit
