sportbikeryder Posted August 18, 2013 Report Share Posted August 18, 2013 Seems quite a few of the I/O are different from each other, i.e. not all DO can be set up the same. It would be nice to have some sort of chart or table in the help file showcasing the possibilities for each I/O Currently, even the PWM rates are different for different pins. Aux out 1 will allow up to 200000 Hz pulse frequency (I assume this is an error, otherwise it could make one hell of am analog out with an RC filter) Aux out 2, 3, 4, 5 will go to 500Hz Aux out 6,7,8 will go to 300Hz Ironically the unused coil drivers cannot be configured for PWM out, but can be set up for a PWM test up to 300Hz.

Scott Posted August 19, 2013 Report Share Posted August 19, 2013 John, You are right, this would be a very useful thing to have. I will add this to the list and try and push to get it done sooner rather than later. Cheers, Scott Quote Link to comment Share on other sites More sharing options...
sportbikeryder Posted August 19, 2013 Author Report Share Posted August 19, 2013 While on the topic, is the max rate of AUX 1 really 200000Hz as allowed in programming via PC Link? Quote Link to comment Share on other sites More sharing options...
Scott Posted August 20, 2013 Report Share Posted August 20, 2013 Hi John, No, Aux 1 can not really do 200,000 Hz. Like the other Aux channels, PCLink should restrict their maximum rate. Thanks for pointing out the problem. Aux 1 to 4 are hardware driven, so can do a higher rate than the other Aux channels. The maximum rate we (normally!) enable Aux 1 to 4 to do is 500 Hz, and the other Aux channels 300Hz. Above these rates we find that the accuracy starts to fall off.
