LPC18xx/43xx FreeRTOS blinky example

Detailed Description

Example description
Welcome to the FreeRTOS basic blinky example. This example starts up FreeRTOS and creates 3 tasks. Tasks 1 and 2 blink different LEDs at different rates. Task 3 outputs a tick count to the debug channel (UART) every second.

By default, tickless idle is used with this example for FreeRTOS. Normal tick operation can be used by setting the configUSE_TICKLESS_IDLE definition to 0 in FreeRTOSConfig.h.

To use the example, connect a serial cable to the board's RS232/UART port and start a terminal program (115.2K8N1) to monitor the port. The LEDs will also toggle based on the task execution.

Special connection requirements
There are no special connection requirements for this example.
