Dan Ghiciulescu / Mbed 2 deprecated FRDM_LCD4884

Test application for the LCD4884. It uses the LCD 4884 from SainSmart / DFRobot, the on board accelerometer and RGB LED.

Dependencies:   LCD4884 MMA8451Q mbed

/media/uploads/COX/mbed_pic_s.jpg

This is the first version.

- I want to add support for a smaller font (like 5x6).

- Update the 5 way read and de-bounce.

It was my first try with MBED on the FRDM KL25Z board and LCD shield.

!!!!!

The shield needs to be modified to work correctly. It has the 5V routed to the 5 way switch so it is more than the 3V threshold for the ADC.

!!!!!
