I set the ADC and interrupt for the boost pid circuit, and the PID setting is rewritten according to the Wikipedia code.
zh.wikipedia.org/.../PID controller
previous_error = 0
integral = 0
start:
error = setpoint-measured_value
integral = integral + error*dt
output = Kp*error + Ki*integral
previous_error = error
wait(dt)
goto start
And expected to use PID to control the boost output voltage, I connected the adc A0 pin on the f28335 (as shown in the picture),
And use a variable resistance of 10k to simulate the voltage received in AO/100/4095*600 (analog input 0~600 output voltage)
The current problem is that CMPA.half.CMPA will be full
May I ask what restrictions should I add, when boost output comes to my pid controller, it can control pwm?
The attachment is my code, the ccs version is Version: 6.1.1.00022
