enl 227 Posted July 2, 2015 Share Posted July 2, 2015 Using a g2553: Any suggestions for doing PWM using the internal reference for the high so that Vcc doesn't need to be regulated? Battery powered application so not using a regulator is desirable. Only way I can come up with is use P1.4 as the PWM output, after setting up the reference, toggling ADC10AE.4 in software, otherwise configuring the pin for output and a value of 0. It works, but it is kinda ugly, so a more elegant solution would be nice. The application is driving an analog meter movement, so the current is in the ballpark of 200uA full scale.
