This directory contains useful libraries to help you get started with Hornet.
irq.h provides the essential functions to utilize interrupts in Hornet. You just need to include irq.h in your source file, and compile irq.c with it. You can then define your interrupt handler routines in your source file. For example, if you wanted to use timer interrupts, you would define the mti_handler() function in your source file. See the examples in the test folder for more details.
uart.h provides simple UART data transmission functions. However, note that this library will only work with the UART module provided in the peripherals directory.
