' This program demonstrates POLLIN, POLLOUT, and the use of the POLLMODE
|
||||
' instruction. Connect active-low inputs to pins 0, 1, 2, and 3. Then
|
||||
' connect an LED to pin 7. The program will print "." to the Debug
|
||||
' window until one of the alarm buttons are pressed. This will cause
|
||||
' the termination of the main loop. At this point the program will
|
||||
' save the latched bits, clear them (and the polling process), then
|
||||
' report the input(s) that triggered the alarm.
