Posted on July 24, 2005 at 08:37WoRo, Thank you for the detailed explanation. I think I finally understand what is happening now :) *** I think you can solve your problem very easily if you know how the whole PWM generation depends on the ART COUNTE...
Posted on July 22, 2005 at 08:19WoRo, First off, I agree with and/or understand all of your latest comments. My main problem is why do I have to put more than 5 into the PWMDCRx register (in my example) to start getting pulses out of the PWM? page 6...
Posted on July 21, 2005 at 09:48WoRo, On page 66 of the manual. DUTY CYCLE REGISTERS (PWMDCRx) Read/Write Reset Value: 0000 0000 (00h) However, I find that I need to add 5 to the duty cycle value that I put into the PWMDCRx register if I want to get...
Posted on July 18, 2005 at 09:17WoRo, *** To read the port value I only change the output from DDR/OR: 1/0 (open drain output) to 0/0 (floting input) and backwards keeping DR=1. *** That is a safe transition for you, so all you need to do is change ...
