#71942 - Ramping up Freq with PCA |
Dear Guys,
I'm using an P89C51RD for an application where a variable freq. is required from 1Khz up to 16Khz at a Fosc of 22Mhz. Using the PCA of P1.3, I'm able to generate a freq of 16Khz with a 25% duty cycle with no problems. The only glitch here is that my stepper motor driver needs to be driven with a starting freq of 1Khz and ramp up to 16Khz at steps of 1Khz in order to get the best speed. Does any one have a good example ? |
