pulse counter

[stephane]

Hello,

Would it be possible to use a MOD-IO or MOD-IO2 board to count pulses up to 100 Hz (input: dry contact) ?
The ATMega microcontroller seems to be able to do that (increment a counter based on an external signal), but would the hardware on the MOD-IO be enough or some additional signal conditionning HW is required ?


Thanks,

Stephane

MOD-IO will have no problem to count pulses but the current firmware have no such functionality, you have to implement it by yourself, the hardware can count even higher frequency
