/**
 * Remote debugging on STM32 using the "Cortex Debug" extension.
 *
 * Copy one or more of the configurations items below into .vscode/launch.json
 * to add those debug options to the PlatformIO IDE "Run & Debug" panel.
 *
 * Examples for BigTreeTech SKR 2 (USB) and Native Simulator. Modify for your own build.
 *
 * NOTE: The PlatformIO extension will remove items when regenerating launch.json.
