Migrating sensorless FOC codebase to a custom hardware board

Hi there!

Is there any document, tutorial, or user manual that provides a step-by-step guide for migrating an existing sensorless FOC codebase for PAC52 or PAC55 EVAL boards to PAC based custom board hardware? Specifically, something that explains how to adjust and reconfigure the related peripherals like ADC, PWM, and others?

Hi AhmadStevie,

We currently don’t have an app note or documentation for migrating to a custom board hardware.

However, adapting the FW to a custom board is pretty simple. Especially with the help of our “PAC FOC Application FW” serving as a reference. You can find here: PAC5524 - Qorvo.
Our PAC FOC FW project, includes board supported files for all PAC EVKs, as well as a custom .c/.h files intended specifically for custom board hardware. You can clone our existing PAC55xx Eval Boards files as a reference for your custom board.

Here are steps you can take:

  1. Open our PAC55xx PAC FOC project.
  2. Navigate to the pac_foc/pac55xx/board folder to view all EVK board files
  3. Clone an existing EVK board .c/.h files into the custom .c/h files
  4. If your custom board uses a 1-shunt current sensing setup, refer to board files with 1-shunt in their names.
  5. These board files configure all key peripherals, such as the gate driver, diff amplifiers, ADCs, and timers.

Let us know if this helps!
