There are docs(helps) about interrupt and its handler under text mode, but what about GUI (photon)
deal with the interrupt.
I think my application(elavator indicator) consists of a driver process that talks to the I/O board
and contains an interrupt handler to deal with the board’s interrupt. and also have a GUI
process that will display an indicator window when told to do so by the driiver.
Can you give me a program template , or may be a example, the best ? Thanks.
