I'm not planning on the LCD module making it to the final configuration of my build, but in many ways this video makes the LCD the first sub component to achieve "completed" status. I take the schematic work from Part 93 and design a PCB to drive the LCD. I also design and 3dprint a support.
0:00 Introduction
0:48 PCB Design
4:15 Soldering
9:22 Cad
13:22 Assemble
14:08 Finish and Test
I'm waiting on a delivery before I can complete the final module in the ALU but I wanted to do this anyway so we'll have a moment when the CPU is entirely PCB.
I have experienced some glitches on the enable line which I cleaned up with a low value (1nf) cap, I'll investigate this a bit more when I get some time and maybe report back.
