* This demo is configured to execute on the ES449 prototyping board from | |
* SoftBaugh. The ES449 has a built in LCD display and a single built in user | |
* LED. Therefore, in place of flashing an LED, the 'flash' and 'check' tasks | |
* toggle '*' characters on the LCD. The left most '*' represents LED 0, the | |
* next LED 1, etc. | |
* | |
* There is a single genuine on board LED referenced as LED 10. | |
