ST7735 for AVR

Please note: This repository is archived. However barskern has kindly agreed to continue maintaining this library. Please go to: https://github.com/barskern/avr-st7735 for the latest version as well as for issues and pull requests.

My simplified plain C version of https://github.com/adafruit/Adafruit-ST7735-Library and parts of https://github.com/adafruit/Adafruit-GFX-Library/

Use at your own risk!

Tweaks

By LongHairedHacker:

Uses my own bitmap format for fullcolor and monochrome bitmaps
Faster line drawing based on: https://github.com/adafruit/Adafruit-GFX-Library/pull/36
Faster font rendering based on https://github.com/adafruit/Adafruit-GFX-Library/issues/69
Refactored draw_char function that does not load glyph struct twice

By Massey101:

Added support for bitmap clipping
Added JAYCAR screen for XC4629 support

By barskern:

Make target for linking a static library

Usage

Connect the display to the following PINS:

JAYCAR screen and ATMEGA328:

Screen	AVR
VCC	5V
GND	GND
CS	PB2
RESET	PD7
A0	PD6
SDA	PB3
SCK	PB5
LED	3.3V

Set the environment variables for:

AVRMCU - Your avr chip
F_CPU - Your clock speed
ISPPORT - programming device

Modify include/st7735.h:st7735_type to your screen. (I have no idea how to figure out which is which)
Run make flash
