PWM component

CAL = Code Abstraction Layer - Allows one code base to run on a wide range of chips. A low level implementation giving direct access to the Pulse Width Modulation peripheral.

Component Source Code

Please click here to download the component source project: FC_Comp_Source_PWM.fcfx

Please click here to view the component source code (Beta): FC_Comp_Source_PWM.fcfx

Detailed description

The ChangePeriod macro must be called at least once before calling the Enable macro to configure and start the PWM timer resource.

Examples

No additional examples
