Functional Description

This LED output can drive any general purpose LED with up to 10mA of current. The intensity of LED is controlled by 1-byte variable, which is in range from 0 to 100 (percentage of maximum intensity).

 

Hardware Interface: The PSoC pin sources current to a LED or sinks current from a LED through a current limiting resistor based on the property selected by user.

 

Software Interface: The LED intensity is controlled with an 8-bit unsigned byte and is in range from 0 to 100% of period (from MIN to MAX intensity).
