can i control pwm voltage with refmux?? No.
The PWM is pure digital. Do not change the period, but change the compare value between 1 and the period value. That will give you a 0 to 100% duty cycle.
The output to the LED is a square wave which you may convert with an R-C ladder to an analog voltage. Remember that you cannot control an LED with a voltage. In this case it is switched on/off at very high frequency with varying duty-cycle.
When you need a REAL voltage then you should use the IDAC and a resistor. This configuration is not able to deliver much current, but it is precise.
When you tell us what you want to perform exactly, we might give you some suggestions.
Thanks bob for your fast responce,
see attached data sheet. its a XTR117. i want it in Temperature transmitter as 4-20mA loop. but i thought psoc-4 is very low power consumption. but when i connect with XTR117 than psoc-4 consume 12 mA power consumption. i want only 3.8mA max power consumption from psoc4 side.
here i have to also sense rtd temperature and thermocouple voltage with psoc-4 parallely.
is it posible with psoc-4 to do this process??
See this application note for power reduction. Debugging uses quite a lot of mA.
For sensing several different analog sensors, look at the components under "Temperature management" in the component catalog of Creator.
