PWM 13-16 Replacement Code

[Mike Bortfeldt]

Kevin,

I would expect that the code should work fine. We (1126) used my version throughout the 2006 season without any issues. Your increase in gain from 40 to 50 is probably a good idea, as we found one of the Victors did not quite go to maximum at the high end (2 msec) without recalibration. The additional 25% on range should easily eliminate this potential problem. You may want to think about modifying your "temp_pwm_xx" calculation so it doesn't require the signed int multiplication. This adds a fair amount of execution time to the routine (relative to how quick it could execute, not to overall processor usage which is extremely minor). It also requires the use of the MATH_DATA section so if someone ever wanted to use the routine from within an interrupt (why? I don't know, but I never rule anything out), they would need to save that data section. I do like the addition of the CENTER & GAIN options it allows for much more flexibility.
