I'm having a trouble here, but I think it hard to solve. I'm driving 8 leds by software PWM, all with 8bit depth pwm. The intensity of each led is controlled by an incoming serial data, a byte arrives at every 44uS continuosly
1) that is about 200k baud are you really feeding that fast? 2) show your serial ISR 3) what does the hardware look like 4) what dos the "serial data" look like Erik |
