LPC17xx/40xx uC/OS-III blinky example

Detailed Description

Example description
Welcome to the uC/OS-III basic blinky example. This example starts up uC/OS-III 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.

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

• Embedded Artists' LPC1788 Developer's Kit:
  
• Embedded Artists' LPC4088 Developer's Kit:
  There are no special connection requirements for this example.
  
• LPCXpresso LPC1769:
  Need to connect with base board for using RS232/UART port.
