This project serves as a template for work with the Freescale FRDM-KL46 board. Support will be added to all on-board peripherals, sensors and I/O.
Dependencies: FRDM_MMA8451Q MAG3110 TSI mbed

Project Information:
Theory
This project has been created to serve as a template for those who wish to use the Freescale Freedom FRDM-KL46Z board. Existing drivers within mbed have been brought together and board specific configurations for certain inputs and outputs have included.
Libraries
- TSI (source: http://mbed.org/users/emilmont/code/TSI/ ) Capacitive Touch library to support the on-board Touch-Slider
- FRDM_MMA8451Q (source: http://mbed.org/users/clemente/code/FRDM_MMA8451Q/ ) Freescale MMA8451 Accelerometer connected on I2C0
- MAG3110 (source: http://mbed.org/users/mmaas/code/MAG3110/) (based on: http://mbed.org/users/SomeRandomBloke/code/MAG3110/)
