PWM6 on LPC2148 does not work
I'm using a Olimex LPC2148 board, and have a problem with the pwm
output on PWM6. PWM on all other channels works fine, only the pin 0.9
PWM6 does not work.
My code contains only the start up code, and the following lines:
PWMMR0 = 1023; // set upper edge value
PWMLER |= (1<<0); // latch value
PWMTCR |= (1<<0) | // counter enable
(1<<3); // PWM enable
PWMTC = 0; // reset counter
PWMPR = 0; // prescaler settings
PWMMCR = (1<<1); // reset on PWMMR0
PWMPCR = (1<<14); // enable PWM output 6
PWMMR6 = 512; // load value
PWMLER |= (1<<6); // latch value
But the pin remains low. I've looked for all write operations to
PINSEL0, but 0.9 is changed only in the lines above.
the WinARM package. The PWM examples uses only PWM1 to PWM5, so I
added the setting of the PWMMR6 register. All other settings (PINSEL,
latch registers, etc.) for PWM6 are already made. But I had no
success, the output on PWM6 always remains low.
Has anyone an idea?
Thanks in advance
