## Questions?

- [ ] write them here like this
- [x] Is the panic handler only for runtime errors?

This panic handler is only for runtime errors, not for exceptions. But `#[exception]` lets you define an exception handler and overwrite standard behavior.
HardFault is the main exception

- [ ] Have the materials been verified with an M1 mac?
- [x] How to turn .rs files into .hex
1. you can use a system tool like (GNU) objcopy
you can Rust tooling like rust-objcopy and cargo-objcopy. those come from the cargo-binutils crate https://crates.io/crates/cargo-binutils
2. you can use the ihex library. https://crates.io/crates/ihex
