Putting characters on a 20x4 character LCD with nothing more than a handful of switches.

Unfortunately that write up is in assembly. I printed both Parts out hoping to use it but discovered it wasn't in C only after printing.
He said 8-Bit and is working with an LCD screen using only buttons and switches. 8-Bit Guy collaboration confirmed! It makes so much sense, David is building a computer.. Julian is building a computer… They both are working with older electronics even by using the Character LCDs
Where abouts in the UK are you? I'm in Southampton! Would be great if we can collab at some point! 😁😊
Dry connection. Logic probe
Switch bounce
i have the article as well when i tried it i used a power supply which help not having problems
Today I learned to count to 4.
1 3 2 4.
My first computer was an IMSAI 8080 and bytes were entered using switches on the front, no keyboard. The switches were better, but the idea is the same.
$08 is the standard ASCII hex character for backspace.
That mag article on talking to HD44780 displays by some bloke is the very one I used to build a radio controlled clock using a 16×2 and a 16Fxxx PIC – not until about 2012 though, in keeping with the lengthy timescale theme here :o)
Any chance of doing a quick video on your setup for filming? When you search for videos about it you always get the guys that have stupid expensive setups costing thousands, that's probably out of reach for most people. I get the feeling that your setup is much simpler and you still manage great results. I think I also heard you mention that you're using windows movie maker and not some silly expensive software, so it would be good to see your work flow for the editing process as well.
I used that article to learn how to drive LCD displays for my HNC project way back in 1997. Never realised who wrote it and have been watching this channel for a few years now.
oooof give me i2c… so much simpler to use
Wow 👍😄
When will JLCPCB offer Purple solder mask like PCBWay?
Neat. The 8-bit guy has a video on these. He also encounters key bounce and other issues you did.
