Martin Kojtal / tsi_sensor

A library for Freescale MCU which contain TSI peripheral, just for Kinetis L version. Because they use "lighter" version of TSI peripheral.

Dependents:   kl25z-tinyshell-demo tsi_slider_light_senso_LED frdm_tsi_slider_led_blend demo_slider ... more

This library is "fork" of the TSI library created by the mbed team.
