Ed Witte / Servo

Sample Servo / LCD code for KL46Z. Display slider value on LCD and set servo position according to slider. Sample code for RS

Fork of Servo by Simon Ford

Demonstrate SLIDER, SERVO and LCD

Servo output is on port pin PTC1 Servo must be powered independently from KL46Z Delay of 1-2s out of reset caused by unknown issue.
