AM32 High Speed External Clock Setup

The High Speed External (HSE) clock is an optional feature that can improve the performance and stability of AM32-based ESCs. By using an external crystal oscillator instead of the internal RC oscillator, you can achieve:

  • Enhanced temperature stability - external crystals maintain frequency accuracy across a wide temperature range, unlike internal RC oscillators which can drift significantly as temperature changes

This tutorial guides you through the process of setting up and enabling the HSE clock for your Vimdrones ESC development board. The setup involves connecting an external crystal oscillator to specific pins on your ESC and configuring the firmware to use this external clock source instead of the internal one.
