Inquiry Regarding Achieving the Highest Resolution for Signal Tracking in External Mode

Currently, I am working on a project that involves signal tracking, and I am specifically interested in understanding how to maximize the resolution when performing signal tracking in external mode with the C2000 MCU. I would greatly appreciate any guidance, suggestions, or best practices that you can offer on this topic.

Hello Tala,

I understand that you are trying to enhance the precision with which you can track signals when using a C2000 microcontroller in external mode.

To optimize signal resolution during tracking, please consider following steps:

• In the ‘ADC’ block parameters, set the ‘ADC resolution’ to the maximum supported by your C2000 MCU.
• Smaller samples allow more frequent update, so you can minimize the sample time in the ‘ADC’ block, the total sample time is the sum of ‘Acquisition time’ and ‘conversion time’ parameters.
• Use fixed point data types in the Simulink model, as fixed-point arithmetic can offer better precision over floating point.
• Minimize the delay using filters and amplifiers.
• Increase the data transfer rate in ‘external mode’ settings.

To know more about fine-tuning the hardware setting and C2000 microcontroller block set, please refer to the following MATLAB documentations:
