I need to know how to program the intern timer, or does a timer not excist in the Ras Pi?
I must learn to program the GPIO´s together with the intern timer:
Here is my task: time based programming of the GPIO4
It is a starting maskin for sailboat racing:
To start the program, i have an extern switch, that even starts the first signal (hooter)
After 60 seconds, the program must set the GPIO4 high again (for appr. 30 milliseconds).
Then, after 120 seconds, the program must set GPIO4 high again ( ” ” ” ” ) to give a third signal.
Finally, after 60 seconds, the program must set the GPIO4 high again ( ” ” ” ” ) for the final start
signal hooter for all boats.
I´m very exited, programming this little wonder maskin, and i would be very thankfull to you guy´s, if
you would be able to help me now!
(i´ve three other projects, when i finished this one!!)
