What're you doing tonight?

So my friend and I just killed a 12 pack now we're off to Harvard Square in Cambridge to play big buck hunter...PRO motherfuckers. What're you guys up to tonight?
 
Crashing at my brother's then going to the Manayunk Bike Race tomorrow. I think I am going to be pretty plastered all day tomorrow.

Only a 12 pack between 2 people??? That's like Taco Bell mild weak sauce.

Seriously. Killing 12 of these between two people, on the other hand, is a different story. 😛
 
Right now I have my fingers crossed for a party to happen tonight. It doesn't sound too promising, so I'll probably just end up sitting around playing some games.
 
I had been planning to figure out how to make this display light up specific individual pixels for something I'm working on, kind of a side/free-time project at work. Unfortunately, Lumex doesn't seem to have embraced the Intarwebs revolution, and as such, they don't make full datasheets available at their website. You evidently need to call and pester a CSR to get a copy of one.
I think I've found one; a website somewhere said that there's a 64 byte chunk of RAM, CGRAM, on many LCDs, which can be used to store custom-generated characters. So that's definitely good, and it can store up to 8 characters, which is also good.

Problem though is still that without that datasheet, which may be sitting on a server at work, I can't put together any code to get it to do what I need.

Somebody buy this man a beer!
 
Hanging out in the parking lot of a local Pizza Inn, leeching some Wi-Fi action.

Later on, gonna go home and paint and clean up. SO EXCITING!

I'm going to be doing some LCD interfacing tonight too. :thumbsup: This LCD.

As far as your project goes. Be aware that that LCD already has a controller on the back. Probably the HD44780. That controller exists on most of those character displays. So you want the datsheet for that chip. HD44780 data sheet

Interesting, I've got a fair bit to read, apparently. I wouldn't have even known enough to have been looking for a "controller" sheet.😱
The two datasheets available at Digikey are only one page each, and aren't particularly useful - kind of like a GPS module I had to work with. Its entire datasheet was also two pages long. Page 1 was more like a product brochure, and page 2 had the pinouts. That was pretty much it.
Its replacement has a manual/datasheet that is 47 pages long, plus a firmware and commands guide that is 103 pages long. THAT is a datasheet. 🙂
(Or the PIC chip I've had to work with, it's got >300 pages.)

I'm getting a crash course on electronics and computer engineering while at this job. My college time was for mechanical engineering.
Not that I'm complaining. 😀


 
Just finished a script earlier today, gonna polish it up and combine it with another working one I have (why run two when I can run one?). Probably going to seriously break something during the merge, if not...then either watch some Dollhouse, work some php, or plan out how I'm going to redo my water loop.

Supposed to be going out later tonight because my friend got laid off and doesn't want to sit at home and mope about it. =|

Let me know if you need any help. I was just doing a very similar project a few weeks ago (controlling a screen pixel by pixel). Granted the screen was graphical and not a character display. I'm not sure what the limits are of the controller on that character display. I'm sure you can make custom characters, but I'm not sure if you can get pixel access.

And once you've gotten this far. There is really no course which teaches you this. Even in my computer engineering courses, they don't teach this. You just gotta figure things out on your own.
