AT90S2313 UART Driver

The driver which works with at90s2313 microcontroller from atmel. A blocking only version with some hacks.

Why ?

The general implementation for AVR which could be found on internet does not work at all, uses interrupts and buffers which is an extremely bad idea for device with 128b of memory.

Usage

It works just fine as 9600 8N1, the 8bit mode is the only supported mode.

The driver consists of only 3 functions:

uart_init(9600); // which initializes UART
int uart_getchar();
uart_putchar();
