TMS320F28027: sensors for interfacing analog signal with f28027 picolo launchpad

Part Number: TMS320F28027


hello 

I am having problems regarding interfacing of f28027 with analog signals (current, voltage). I am programming my device with Simulink by using hardware support and my processor needs input from circuit to implement closed loop control which is current and voltage. Currently, I am using hall effect current sensor acs712 and voltage divider but they are not working. I also need to know which data type is selected from unint8, single, double, unint32  for ADC pins to enable them to read the data.     

  • Can you please be more specific as to what issue you're seeing? What is not working about the current and voltage feedback circuits? Are you seeing the correct value for the inputs in the ADC result registers? Is this more of a Simulink question than a C2000 question? Please elaborate.
