Title: Relay state
Post by: pepe492 on January 28, 2014, 05:41:39 PM
Hi,

Is there any possibility to read the state of the relays from the MOD-IO extension board?

Thanks.

There is no existing hardware on the board to do this. Your only feedback would be to modify the source to send back the ON state so that if you lost communications or your main board app was restarted, you could read the current ON state of the relays (assuming the MOD-IO was not reset at the same time, in which case the relays would be OFF)
