Hi Group,

My plan is to read incoming pulses on the 8 input lines of a port, store/totalize in a long variable and transmitted when requested.
The pulses are generated by 8 electricity meters, issuing 1000 pulses per kWh. (1 meter per port input)
In order to read a maximum of 10 kWh the pulses from each meter will appear at approx 2.5 seconds interval.
The possibility do exist that pulses from 2 or 3 meters will arrive simultaneously.
To overcome the problem of simultaneous pulses I thought of using interrupts but I am not sure if interrupts can be done on 8 input pins.
Also the operation of reading/totalizing/storing of the pulse data should not be affected by the montly request for down load.

Unfortunately I do not have a try-ed program to attach as I am still trying to figure out what to do.

Has any-one perhaps got some info or a suggestion other than PicBasicPro for this type of operation.
Any support will be appreciated.

Thank you all in advance
