Preliminary
2.3 Debug LEDs
Six on-board Light-Emitting Diodes, (LEDs), are provided to allow real-time debugging for user
programs. These LEDs will allow the programmer to monitor program execution without having
to stop the program during debugging; refer to
Figure 2-1
.
Table 2-2
describes the control of
each LED.
Setting GPIOA0, GPIOA1, GPIOA2, GPIOA3, GPIOA4, or GPIOA5 to a Logic One value will
turn on the associated LED.
