Modified version of the Kentec_35_SPI library included with Energia to add support for the TM4C129 Connected LaunchPad.

Kentec_35_SPI Library

This is a modified version of the Kentec_35_SPI library included with Energia and developed by Rei Vilo.

This updated version adds support for the TM4C1294 Connected LaunchPad and addresses a couple specific issues with my Connected Status Monitor project.

Changes From Version 1.0.0 Library Included with Energia

TM4C1294 Connected LaunchPad Specific Changes

1. Add support for 12x8 font (font size 3).

2. Default to standard SPI pins on the BoosterPack 1 connectors (pins 7, 14, 15 on J1/J2). The tivac platform core has these pins configured as SPI module 2.

3. Use digitalWrite() instead of analogWrite() for the LCD backlight, since my setup does not use a PWM pin for the backlight.

Other changes

1. Disable call to _getRawTouch(), as it frequently hangs on my setup.

Usage

Other than the changes listed above, this version should work the same as the library included with Energia and should support msp430, msp432, and tiva platforms.

The included example program and documentation can be used to understand how to use the library.
