Hello Friends,
I have to measure PWM signal pulse width (pulse repetition frequency is 50Hz) on NXP LPC1343 . How can i measure the pulse width? and i have 4 PWM signals whose widths must me measured at the same time. How can i measure 4 pwm widths at the same time using NXP LPC1343 ??
Thanks in advance
Note that you have selected a processor with quite limited support for capture inputs.
It looks like the chip can just about manage 4 capture if you consume your two 32-bit and your two 16-bit timers.
You might have to settle for pin-change interrupts and have the ISR manually look up the current count of a freerunning timer. Obviously with the latency of the ISR introducing measurement errors. It all depends on if you need timers for something else.
