Posted on June 14, 2006 at 16:27Hi all,
In ST7FLITE29 a PWM step are defined by VDD/1024.
At 5VDD is means approx 4.9mV/step.
I want to produce ( and repeated in series of productionboards ) a very stable PWM-level not influenced by the tolerance of the voltage regulator supplying VDD ( voltage regulator accuracy normally around +/- 5% ).
The goal is around +/- 0.5%.
Have anyone a smart software idea ?
