This example has been tested with stm32h743 in a Holybro Durandal flight controller, with an externally connected M8N GPS module containing a tca62724fmg rgbled.

cargo run --example sweep --target thumbv7em-none-eabihf

The memory.x ,.cargo/config, and dronecode.gdb files included with this crate are configured to run this example by connecting to the Durandal via a dronecode probe (or similar, such as a Black Magic Probe)
