Plan:
This week I decided to work on the control loop. I decided to add a simple adjustment scheme to the 5 mS system timer event. And then create a way to change the required voltage in increments of 0.1 Volts starting at 10.0
Implementation:
I created a local “static” variable in the events.c file for the target voltage. I then created a function to set this variable target_voltage and another function to get the value of target_voltage. I then added a simple if statement into the 5ms event that increments the duty cycle of the Sigma Delta if the measured value is too low and decrements it otherwise. I compiled and tried this, Vpp is ugly.
