These LCD videos are fine examples of the power of "first principle thinking", which is an invaluable skill/mindset that I fear today's kids are missing out on. One problem with today's technologies is that all the science and engineering are neatly packed into sleek packages that try hard to portrait themselves as "magic"; "warranty void" if you so much as remove a sticker. I applaud the 8-bit-guy for his great works not just for their nostalgia value, but also for the "tinkerer spirit" they inspire, which shouldn't (and hopefully wouldn't) ever become obsolete in today's 64-bit world and beyond.

Abstraction is a useful concept as long as you understand what’s going on inside a bit. If you wanted to make a simple programming language in Minecraft then you probably think that you couldn’t. But if you use abstraction, that may be no problem.

I spent 2 years doing a CDT Technology GCSE, essentially learning how electronics worked and I learnt more from these 3 videos than I did in the entire 3 years. I wish my parents had talked to me about it and then pushed me to change to a different course. That said, there's a lot I didn't understand in this video but it's less "magic" and more LCD responding to electric voltage. If I was a science teacher I'd build a lesson around this.

As a programmer that has always kind of neglected the hardware side of things, your videos are absolutely invaluable to me. Keep up the good work :)

David, it's frustrating that your DIY board turned into a _"No-Can-DIY"_ board. Will you please do a video in which you interview David Hunter about the requirements of interfacing with the 6502? Perhaps his buffer logic could serve as a standard interface between the 6502 and other electronic widgets. *THANKS!*

@BrekMartin

5 жыл бұрын

There’s no requirement for any board. You could connect the LCD straight to the expansion port. Just ignore the part at 3:00 and read the LCD data sheet instead.

@AiOinc1

4 жыл бұрын

The 6502 drives it's data lines after setting the address. LCD controller is faster than the 6502. 6502 sets the address, which causes the LCD to latch the data on the bus before the 6502 has actually even attempted to write to the bus yet, causing the LCD to read in null characters each time. Friend put some buffering on to slow the signal down so that the 6502 can finish setting data before the LCD is triggered. It probably would work without this if you did the address decoding yourself instead of using the I/O lines, and/or switched to assembly instead of Basic. Look at any timing diagram for the 6502. The C64 uses a 6510 but it's the same story.

David Hunter are you the guy who had the boards made? Where do you order your PCBs, and how do you design them? I've been needing something of similar nature (not for character LCD, for actively converting internal display signals).

Nothing better than tuning into a good vid after 11 hours of sleep and way to much summer school. I'm in Comp Org 1 now and this should help make your videos more interesting.

love the "42" reference on the last video." Ford" would be impressed. couldnt leave comment on part 2. really enjoyed this series.i was in electronics school back in the "dark ages" (77-83) you bring back lots of memories.

I quite like the drawing speed on the LCD actually, it's charming and suitably retro

I've just found yourchannel and watched the three LCD videos, they're fantastic. I've always wondered how they were driven and I never realised they were so simple. The whole 8-bit thing really takes me back to my youth too.

I love your explanations! So informative. I’m glad you finally finished this series of videos!

Hey David, I'm here to just say thank you for teaching me this knowledge because i have a plan to make a device that will act like a Pip-boy® from fallout, and its going to be modular, so thanks to your understanding of lcd screens I know how to connect almost everything, I hope my project is a success. Thanks a lot again.

"About that beer I owe ya!" That's the feeling I get when I see this in my sub box.

Awwww these are the cutest series you made back in the days! Thank you for filming!

You sir have the best planned videos on KZread; most enjoyable and I feel like every video is a journey!

I love your vids David, they have had the same good quality for the 2 years i have been subbed to you. I have been waiting for this for a while too.

This is probably my favorite series of videos that you've done. Great to see another installment, and hoping for a part 4!

The thing I love the most about all this is that it has actually taught me more about IO and programming than most of my actual computer programming classes, and enough of the basics to understand exaclty what's going on in a given motherboard/connector.

It's always a joy to see your videos on my feed

I loved this little mini series, thank you for that. It so happened that I was actually searching on topics on how to decode the Nintendo DMG01 display and how one would go about programming that and replacing the screen with a better display and not having to go through the backlight saga. Anyway, as I said, really enjoyed the logic and background, plus the reminder on how easy it was to communicate with stuff on the cartridge and user ports of the C64!

So glad that we get to see the conclusion of this series! It's been a long time coming, and it was definitely worth it! Thanks for the video as always, look forward to the next one! P.S. That typo in the title definitely gave me a chuckle

Once you had the basics in place, you could then make it fancier if you wanted to. For example: 60 PRINT "LINE 1 (16 CHARACTERS MAX)" 61 A$="":INPUT A$ 62 A$=LEFT$(A$,16):REM TRUNCATE LINE 1 TO 16 CHARACTERS 63 FOR L=LEN(A$)+1 TO 40: REM PAD THE STRING TO 40 CHARACTERS BY ADDING SPACES 64 A$=A$+" ":REM THIS IS NECESSARY BECAUSE OF THE WAY THE LCD WORKS 65 NEXT L 70 PRINT "LINE 2 (16 CHARACTERS MAX)" 71 B$="":INPUT B$ 72 B$=LEFT$(B$,16):REM TRUNCATE LINE 2 TO 16 CHARACTERS 73 A$=A$+B$:REM APPEND LINE 2 ONTO THE END OF LINE 1 The rest of the program would be identical. Obviously the program to create custom characters is much more sophisticated. Maybe he'd be willing to put the source code on his website or something.

This whole series of episodes was great!

Thank you Dad for another informational electronics video. Iv watched almost all your videos since I subbed after your restoration of the factory Commodore recently. Don't be afraid to upload restorations on same models either, all your projects are pleasing to watch.

Hi 8 Bit Guy, thanks for your great videos i really enjoy them. Seeing the trouble that LCDs gave even you, it made me feel better about failing with 3 LCD's last time I tired lol! I thought it was just me but clearly they are tricky magic! 😊 keep up the good work 👍

Two uploads in one week, and the Kickstarter crushing all expectations? You’re on a roll, David!

Matrix Orbital has some great LCD screens. I had their MX6 20x2 5 1/4" drive bay USB VFD screen in my Windows XP computer back in the late 1990s and early 2000s. I used it to show the system information from that computer plus a couple custom screens I made up. It was highly programmable and customizable using a software program that came with it.

Thanks 8-bit guy! I feel I get so much info out of your videos that I wouldn't get to see unless I was doing electronics engineering or so! :)

Just AWESOME! You are a guy of my type who doesn't bother to waste time to get into the very deep to fine the real treasure of electronics! However, the difference between u and me is, I'm a fresh graduate newbie and u are a geek! Kudos !

The intro music make in so good mood

Always brilliant. I enjoy your dedication to your craft - thank you.

I remember (rather vaguely now) back around 1982, I had to interface a character display to an 8080 board running assembler. A bit fiddly because the 8080 didn't allow writing data to an address which was a variable, so it involved a bit of self-modifying code. Also I couldn't read any acknowledgement signal back from the LCD because it didn't have enough drive capability to run the 8080 and all its data bus components and wiring. I could have added a buffer but instead just wrote to the LCD slowly enough that it would always work. It was a great project, used as an in-house test system for logic boards. Alas the company I worked for then has long since been absorbed and forgotten, and the (then) brand new factory has been abandoned for decades.

The LCD enable pin is active low (not high) so an inverter is unneeded. Just like your previous video, it might work, but will only lag behind. The same reason your button worked when you released it, rather than when you pressed it.

Idea: you can try plug some graphics LCD based on the SSD1963 to the cartridge port - that chip is a full on graphics LCD controller with internal VRAM. Even better if one of the two joystick ports can be used along with some analog sample and hold circuitry to implement resistive touchscreen.

Honestly i also do not like the final solution to get it working. - the complex inverter with a chip instead of a transistor with pull-up/down - the massive pcb with multiple chips and buffers without explaining or schematics. This completely goes off track to the first video showing how "simple" an lcd can be controlled with switches and no ICs.
