Front panel keys

There are 16 front panel keys on the board. If any key press is detected, STLED316S

asserts interrupt. For this evaluation board, the interrupt is sent to GUI. Once the GUI

detects an interrupt, it reads front panel key data on the STLED316S key register. Having

decoded the data, GUI then writes to the 7-segment display the key that has been pressed.

For example if the push button labeled CH6 is pressed, CH.06 will be displayed on 7-

segment display as shown below:
