I'm trying to connect this 50-pin e-ink display to an Atmel ATmega328p for a hobby project.
The biggest design challenge I'm facing is connecting all the pins from the display to the MCU in an orderly way. Originally I was using six 8-bit serial to parallel decoder / shift registers (e.g., 74HC595, chaining them together) then connecting the 2 leftover pins to the MCU directly. But this approach is a mess on the breadboard.
Is there any way to get a wider shift register (e.g., 32-bit or 64-bit) to make things better? Or is there another type of (inexpensive) chip entirely that would work? I've looked at LED drivers, but thought it has too many special features for this application.
Thanks in advance!
