Using Atmega 128 as real time logic units

Post by nanawhite107 » Fri Jun 30, 2017 10:23 am

Currently I'm designing simple digital piano model. I used tons of decoders and And's to build my project. In simulation those ANDs are connected and enables external int0. So that If any button is pressed, this triggers button play function regardless of other processes. But in PCB and soldering i find these ANDs quite annoying. So I'm trying to omit those ANDs by changing my code. Is there any software interrupts that triggers automatically if any single input reaches zero? Or FPGA like component in Atmega 128? or do I have to write button scanning code in every single lines of my main code(I scanned datasheet but didn't reached success)
Here is thedatesheet of 1n4148


74148 is 8 to 3 encoder
