Hello:
Somebody know what is the max.length of wires to connect Ports of Microchip PIC Microcontroller to switches ?
I need connect several switches in matrix configuration with about 3-4meter length wires, and do not know if this length will be excessive and will produce unstable working (by RF interferences, voltage drop, etc..).
I have think about add one ULN2803 to amplify signal, but do not know if really require it.
Regards
