Fork of the Adafruit ST7735R library targeted to the 1.44" TFT with custom high speed monochrome and color drawing routines. Note that this library includes modifications to use a shared SPI module to simplify projects that use the SPI for several peripherals. Read the WIKI to see how to get this library working in your own project.
Fork of
Adafruit_ST7735
by 
Andrew Lindsay
This library is a modification of Andrew Lindsay's ST7735 Adafruit library. It includes custom bitmap drawing routines that work around 15 times faster when using custom byte arrays generated by my png to char array converter.
For more info look to the detailed post explaining the changes and where you can download the converter binaries as well: http://alfredoer.com/microcontrollers-2/adafruit-image-bitmap-generator/
IMPORTANT: One of the main modifications is that this library does not instantiate an SPI object directly, rather it is meant to use a shared SPI object exported in a "board.h" file elsewhere in your project.
The contents of such a file can be something like:
ifndef BOARD_H_
- define BOARD_H_
- include <mbed.h>
- include <rtos.h> extern Mutex spi_mutex; extern SPI spi_port;
- endif
And of course, the objects should be instantiated somewhere (like in board.c) like this (for a KL25z, modify as needed):
mosi, miso, sck Mutex spi_mutex; SPI spi_port( PTD2, PTD3, PTD1);
The rationale is that several modules can use the hardware SPI port on several threads and coexist happily with each other.
