#83467 - Drop in replacement??? Responding to: ???'s previous message |
Hi Raghu
Taking Bruce's idea a little further: Have you considered using the Philips RD2 chip as a drop in replacement for your board. If not, heres why. You could use the on board compare/capture unit to generate PWM output proportional to the angle on one P1 pin (P1.3 to P1.7) and another pin could be the polarity output. You will still need the opamp / filter sections to get the +-10V output. And the basic Hardware pwm will give you only 8 bits resolution. Jerson |
