hi all, recently i made a project call dart board automatic calculator that calculate the score of dart throw. I use 3 pic since i need 64 inputs. I use a oscillator for each PIC (total 3) and a 9v power supply and a 5 v power regulator. Everything fine in simulation but when i applied on real circuit, the calculation become unstable and sometimes lcd display nonsense. I tried all the solution i know but still cant solve it. Please someone help me
hmmmm
im confused...
if i use 1 PIC, how could i connect all 45 input to a single pic???
sshould i used encoder to be the medium between the switches and PIC???
