PWM double edge 3phase test

Thomas Crow

Hi all,

I am testing with a lpc2138 and Keil qvision4.
I've written this very simple test program:

#include <lpc21xx.h>               /* LPC21xx definitions */
void main()
        {PINSEL0 |= 0x000A8000;
         VPBDIV = 0x00000100;
         PWMPR = 0x00000000;
         PWMPCR = 0x00005454;

         PWMMR0 = 0x00000700;
         PWMMR1 = 0x00000020;
         PWMMR2 = 0x00000060;
         PWMMR3 = 0x00000120;
         PWMMR4 = 0x00000160;
         PWMMR5 = 0x00000220;
         PWMMR6 = 0x00000260;

         PWMMCR = 0x00000002;
         PWMLER = 0x7F;
         PWMTCR = 0x02;
         PWMTCR = 0x09;
         while(1);
         }

the problem i have now is that i want lets say PWM channel 2 pulse twice or 3 times within the 700 PWMR0.
so what i want is PWM2 10Khz PWM4 20Khz and PWM6 at 40Khz.
Anyone know if this can be done?

Thanks in advance
Thomas
