Hello Sir
I have a project to log the keypresses from an hall of 60m X 50m area. There are around 500 switches in this area(actually there r 500 users sitting in this hall, each table has one toggle switch,reset switch).
Tables are arranged as 10cols X 50 rows.
I was thinking for a simple matrix logic as its extremely simple and would be cost effective in terms of cabling costs as well as other hardware required.
I have a requirement of running 60 m cables with ttl signals.Is it possible with using BUS Buffers/transreceivers?
ON the computer end i will use 60 bit digital I/O board and write the software which will scan
rows and columns continuosly.
Will be feasible or there is any better alternative...
Please , can u suggest me on this.
Thanks alot
Best Regards
