    Who-da Thunk?

    Actually I was running a forum deciphering test. :D You all failed miserably. No CIA, MI-6 annalist jobs are waiting for you. :p OK, I'll post a schematic or sketch later. Chris

    Who-da Thunk?

    I want to preface this with a bold statement.... I have just about every configuration of RS232 cables and adapters known to man and I have them in duplicate x 10. This morning the wife says.. "Gee, this is odd. This month you didn't buy a single China - Ebay item". That got me to thinking...

    How to remove solder from plated-through holes?

    Mike, you must be a big fan of Hemingway, especially his last short story titled "I Wonder If This Gun Is Loaded"? Chris

    ED, accolades to you for deciphering Mark's sketchy schematics. That's a nice schematic drawing. What app did you create it in? Chris

    Advice on LCD display for Picaxe project.

    Constantine, what's the status of this project? Have you made any headway with your ebay GLCD? I ask because I have your PCF8574A spice model in my Picaxe-VSM library. With it I should be able to duplicate the I2C GLCD you have. Chris Chris

    Advice on LCD display for Picaxe project.

    I had no problem finding the datasheet for the MILFORD-2X16-BKP serial LCD that I used in my spice but haven't found a supplier. Even though Newark and Farnell supply the datasheet?! I think? this is Greek. If it is you'll understand it. They're discussing the MILFORD-2X16-BKP Serial LCD. Let...

    Advice on LCD display for Picaxe project.

    I was tired because it was late when I posted that last night. Not because of your project. I like working on this. OK, I think I see where the confusion is between the serial LDC you have and the one I used in my simulation. The model used in my simulation also uses a I2C buss. The main...

    Advice on LCD display for Picaxe project.

    I'm very tired over here, so I'm hitting the sack. Tomorrow morning I have to setup a new PC for my wife. I'm not looking forward to it as we don't work together well while messing with PC's. Before I shut down I wanted to post this to let you sleep on what you see. I'll explain further...

    Advice on LCD display for Picaxe project.

    Constantine, you purchased a "SERIAL" LCD so how does that make any sense? That slave code for the AXE133 is intended to feed a bare LCD not a Serial LCD. Capice?? Sit tight. I'm going to post something for you to show you exactly what I'm talking about. It's sure to blow your mind! You're...

    No, there's no SerOut command in any of the code you posted. Just try the code I posted. Chris

    Advice on LCD display for Picaxe project.

    There's a very old expression used here in the U.S. when someone doesn't understand what they heard or read. The expression is "It's all Greek to me". This isn't going to mean a thing to you because you're Greek! :p OK back to your problem. Let's try and trouble shoot this in an orderly manner...

    Constantine, your English is a hell of a lot better than my Greek. Is this the serial LCD you purchased...

    Advice on LCD display for Picaxe project.

    I went back and read through more of your posts. All good questions and I confess I've been very distracted over here. I've been deeply engrossed in getting my feet wet in the latest release of the Great Cow Basic IDE. At the same time we have elections coming up in a week and I've been...

    Advice on LCD display for Picaxe project.

    That's unlikely because it doesn't throw any errors in PE6. I haven't seen your modified schematic using the 20M2 in place of the 18M2. Did I miss it? Chris

    Advice on LCD display for Picaxe project.

    You can post the lines of code that brings C.2 high. It should be something like ... High C.2 You do realize you may have fried that port when you forgot the base resistor. Chris Oops, never mind about the code. I forgot it was serial controlled from the master chip.

    How to remove solder from plated-through holes?

    This thread makes me chuckle. For more years than most of our members have been alive I've used a hot iron and rapped the board on the bench. The plugged hole clears easily with the solder flying out and splattering on the bench. Through hole or not! I usually add more solder first so the iron...

    Advice on LCD display for Picaxe project.

    I forgot to mention that if grounding R1 doesn't turn the back light on then T1 went west or the LCD's "A" pin isn't connected to the 5V rail. On that note if you eliminate the PNP altogether and connect "A" to +5V and "K" to GND the back light should light. Does the LCD have an integral...

    Advice on LCD display for Picaxe project.

    Disconnect R1 from Pin C.2, then ground it. Does the back light turn on? If it does then leave it disconnected from Pin C.2 and scope C.2 again. Chris

    Like I said PNP's must be wired like this. Chris
