#180761 - Thanks - that worked Responding to: ???'s previous message |
Thanks for that, It worked a treat.
I was using the PCA for 4 independant PWM channels, but the integral of each of the 4 channels must be <= 100%, I could vary the PWM so that all of the channels ran at 25% (for example) but of course they all finished at the same time. ie they all ran concurrently. Where as I wanted to have PWM1->PWM2->PWM3->PWM4->PWM1 and so on Configuring the PCA as a timer and then turning the ports when an interrupt fired on a match allowed me to run my own PWM sequentially - without having to mess with the PCA clock. Thanks for the thoughts. Regards Marshall |
