I’ve put the below circuit together, lorlin bck1001 reading from 2 eeproms, it works fine,
I’ve also made a circuit for a mc14495 decoder and 7 segment display, it works too,
But after connecting them together, most times the switch/display only operates correctly if I hover my finger above the mc14495 chip,
I’m a beginner so don’t really know what I’m doing wrong, but it did work on a breadboard, someone mentioned power filtering so I read up on that and tried a 100nf ceramic capacitor between 3.3v and ground right next to the mc14495 chip, it didn’t help, any idea what I can try next?
