CLosure INTerrupt handlers

This crate allows you to use closures for interrupt handlers in a heapless, no-std environment.

Cargo features

The HandlerTable type uses a backing array for its closures. To configure the number of available slots, specify one of the following cargo features: isr-8, isr-16, isr-32, isr-64, isr-128, or isr-256. By default, 32 slots are available.

If you’re using a nightly toolchain, you can enable an optimization when calling handlers by turning on the const-fn feature. This will save one conditional branch on every call.

Example Code

See the examples directory for some simple examples.

For a slightly more complex example this repository uses clint to blink some LEDs and measure temperature across a number of interrupts and exceptions.
