Functional Description
This LED output can drive any
general purpose LED with up to 10mA of current.
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 state is controlled with an 8-bit unsigned byte. 0 = Off, 1 =
On, 2 = Blink.
Driver Properties
User Configurable Properties:
·
Current Mode: Specifies the current flow with
respect to the PSoC pin connected to the LED.
The PSoC pin can be configured to source or sink the LED drive current.
·
Blink Rate: The blink rate is adjustable between
0.25 Hz and 4 Hz. Default is 1 Hz.
Non-Configurable Properties:
·
InitialState: This is initial pin
state.
·
DriveMode: This is PSoC drive mode
(Strong).
Driver Specifications
·
Power supply: From 3.3V to 5.25V.
·
Forward Current: 10mA (max)
