Hi Al, [quote userid="392761" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1494574/tms320f280025c-q1-how-to-change-f28002x_int33-model-parameters-specifically-the-trigger-and-adc-conversion-time-settings/5743717#5743717"]As a side note, there are a couple of differences in the model (doesn't affect what I need to do) such as the "Ron" is 860 ohms (not 500), which I'm going to assume is correct for this F28002x-INt33?. [/quote] Yeah, this is correct, you can see it in the datasheet here: [quote userid="392761" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1494574/tms320f280025c-q1-how-to-change-f28002x_int33-model-parameters-specifically-the-trigger-and-adc-conversion-time-settings/5743717#5743717"]Also, the voltage sources VOA-SS3 (ADC) and Vin 3(op amp) are 3.0. should they be 3.3? I may not understand this difference for _int33. [/quote] Yeah that does look like a mistake, they should be 3.3V. [quote userid="392761" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1494574/tms320f280025c-q1-how-to-change-f28002x_int33-model-parameters-specifically-the-trigger-and-adc-conversion-time-settings/5743717#5743717"]I can open and view the U2 (op-amp) model (yellow), but I can't open the ADC model (blue dashed line box) to edit parameters. trying to open (right click) the menu but the "open macro" is grayed out. selecting properties just gave me the "text" information.[/quote] Unfortunately, there is not a way to simply edit the parameters to update the model. The blue text box is just a text box. For example, if you want to edit the acquisition time, you need to edit the Vacq voltage source. Best Regards, Ben Collier
