Hi everybody
I'm doing a project with PIC to check connection of wire hardness.
A wire hardness have two housing, once housing have a 32 pins, connection parallel from one pin of 1st housing to one pin of 2nd housing.
I'm building a circuit using 4 shift register IC ( 74HC595) to output and using 4 74HC165 IC to input as a schematic included below this post.
About an idea to programing, I think I shift one bit to output, and check on input pin, if data right, i'll change to next step.
Because this circuit is using in noise zone, sothat I need a recommend to check a design again.
Please show me if it not correct.
Thanks you.
