Can i use Keyboard GPIO's for Hardware Counter in Q2400


Hi All,

     I am using Q24CL001 Wavecom GSM Module. I had interfaced an external counters in place of keyboard GPIO's. Is it possible?

     can we use ARM processor internal hardware counters for my application in Q24CL001 series (for counting externel pulses? in my application )

If any one has come across such issue please reply

Thanks & Regards
Arise. Ramesh



Don’t double post your question! :stuck_out_tongue:
I think you should clarify what you want to achive, for example the speed of the signals which you want to recieve, but i think you should use a few dollar tiny controller for signal handling.

Why don’t you use the module’s keyboard interface anyway or you want to connet to a computer’s keyboard?
