Hi all, I have an olimex lpc2106-mt pcb and try to program a PWM without success. The Docu is not especially detailed (I think). I tried a lot of register settings(for hours). All I get is a single 88.64 ms pulse on PWM4 at reset that does not change with the match register or pre- scaler value. This code is one example that illustrates my understanding of that thing: //testing PWM4 PINSEL0 |= 0x20000; // select pin 0.08 PWM4 function PWM_PR = 0x0000; // max prescale counter value PWM_MCR = 0x0002; // reset when PWMMR0 matches PWM_PCR = 0x1000; // PWM4 enable, single edge PWM_MR0 = 0x0f00; // match register trigger value PWM_TCR = 0x0009; // set the TC counter and enable the PWMs I would expect a 1.92 kHz frequency from that... Obviously I do something completly wrong. Any help is really apreciated Cheers, Kurt.
