plu_combination#
Overview#
The PLU combination project is a simple demonstration program of the SDK PLU driver. In this example, a number of GPIO pins are connected to PLU inputs and the LED is used to monitor the PLU outputs to demonstrate the configuration and use of the Programmable Logic Unit (PLU) to construct a combinational logic network.

Since the PLU_OUT0 has no external pins on the FRDM board, so only input sources 0 and 1 are supported in this example. Therefore, the PLU_IN5 and PLU_OUT0 do not need to be connected.
PLU input pins connection:
J2-7 (GPIO0_6) to J2-8 (PLU_IN3 PIO0_8).
J2-6 (GPIO0_7) to J1-6 (PLU_IN4 PIO0_9).
PLU output pins connection:
J2-2 (PLU_OUT1 PIO0_13) to J1-5 (RGB_GREEN PIO0_0).
J2-1 (PLU_OUT2 PIO0_14) to J4-5 (LED_BLUE PIO0_19).
Prepare the Demo
Connect a USB cable between the host PC and the FRDM board J10.

LPCXpresso804
Functional Description
The example will configure the SWM for PLU inputs, outputs, and clock input, then configure the PLU module to make it work.
Note: The RGB LED in this case turns on when the pin level is low and it turns off when the pin level is high.
Each of the three LUT elements are connected to the three PLU input sources to control the RGB LED.
