## ATtiny World
A collection of libraries to make use of an ATtiny2313 MCU.
* [Datasheet](https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-2543-AVR-ATtiny2313_Datasheet.pdf)
### Setup
This repository assumes that a Debian-based distro is used. Package names may vary.
#### 1. Used programmers
* USBtinyISP
* [Introduction](https://learn.adafruit.com/usbtinyisp/use-it)
* [Schematic](https://cdn-learn.adafruit.com/assets/assets/000/010/326/original/usbtinyisp2sch.png)
* [Tutorial including firmware](https://cdn-learn.adafruit.com/downloads/pdf/usbtinyisp.pdf)
#### 2. Required packages
* `gcc-avr`
* `avr-libc`
* `avrdude`
#### 3. Initial MCU fuse setup
Note: the fuse bits are inverted! 0 = selected

Example configuration:
# 0xE4 : 8 MHz clock, slow start
avrdude -c usbtiny -p t2313 -i 400 -U lfuse:w:0xE4:m
# 0xDF : SPI flash enable
avrdude -c usbtiny -p t2313 -i 400 -U hfuse:w:0xDF:m
#### Serial terminal apps (RS232)
