Describe the solution you'd like

• Choose which LCD to use (must use I2C or SPI).
• Be able to write characters to LCD.
• Test writing basic custom shape drawings.

Purchasing these two CrystalFontz LCDs. Will decide which size fits my glove better once they get here. Both are compatible with the breakout board listed below. Both devices have Arduino drivers. I plan to modify this code with MSP432 register and SPI code. Also ordered 5 of these ZIF adapters. I can solder the connector to a PCB and plug in the LCD later.

TODO:

• Move IO port/pins into the target_hw_common's systemIO variable.
• Figure out why the drivers are creating garbage on the screen.

Remainder of driver development being tracked in #46.
