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/)
TODOs
- Add support for Segment LCD - intend to use driver in example code: http://cache.freescale.com/files/32bit/software/KL46_SC.exe
