Frank Vannieuwkerke / Mbed 2 deprecated KL25Z_HSI2RGBW_PWM_local

KL25Z RGB LED fade demo using the HSI2RGBW_PWM libary

Dependencies:   HSI2RGBW_PWM mbed

Fork of KL25Z_HSI2RGBW_PWM by Frank Vannieuwkerke

HSI to RGB demo with direct PWM output

Drives the KL25Z on-board RGB LED.
Other demo code, driving an external RGBW power LED : see this page.
