OLED

Hi every one. I was wondering if anyone had any experience with AMOLED colour graphics displays. Can anyone recommend a suitable unit to start with and where to get it from.

Is there an appropriate Swordfish driver module.

Any help would be appreciated.

Thanks Steve, All this advice has been a big help. I now have the touchscreen working correctly and I have been able to test the graphics part of my code. Hopefully a GLCD unit combining both functions should arrive from RS tomorrow. For the icing on the cake, are there any ways to reduce flickering...

I have RS 532-7350, and 627-1747. The data sheets for these displays, and the description provided by RS, are not a great deal of help. I bought the 627-1747 because it seemed to have the same connections as those you specified, however, it doesn't seem to have a touch screen despite it being shown ...

Still no luck Steve, but I think I might have a slightly different LCD unit from you. My LCD has DISPLAYTEC 240320D printed on the reverse. The datasheet I downloaded from RS has different pin connections to the ones you suggested, however RS also supply other units which look identical but on exami...

Late follow up

Got the PicKit2 programmer and it works miles better than the one I was using before.

No problems with programming now and I would thoroughly recommend this programmer to anyone starting out messing with PICs.

Thanks for all the help

Thanks Steve. Seems to be working much better with extra pull-ups. I'm happy I can now get a position from the touch screen which I'm writing to another LCD. I now need to hook up the LCD part of the unit and get some display output. I wondered if you could offer any advice in that direction. What i...

Pull downs on the touchscreen connectors.

I hadn't thought of that. I'll give it a try and let you know what happens.

Thanks David. That looks like just what I need. I've been trying to get the touch screen to work using Steve Wright's module. It seems to work very well, except that a position is returned all the time, rather than only above a certain pressure threshold. I have tried altering the threshold value wi...

GLCD teething troubles

Hi there, Any help would be very welcome.

I'm trying to get going with the 320x240 S1D13700 touch screen graphics LCD (from RS components). I wondered if anyone with some experience with this unit might be able to give a little advice.

Schematics

Hi Steven, I think you GLCD touch screen project is fantastic and I was hoping to use the libraries in a project of my own. I wondered if you might be able to provide schematics for hooking up the display unit. I have the same one from RS components. Thanks for any help and advice you can offer.

Thanks for your help every one. Finally I have a beautiful flashing LED. It would seem that fuse settings are not being correctly passed by the HEX file to my programmer software, or the software is not interpreting them correctly. Each time I load the HEX, the OSC fuse is reset to LP, rather than H...

OK. Again, thanks for all the advice and suggestions. I now have a brand new 20MHz crystal and a pair 22pF caps. I've tried all the suggestions but still no luck from the flashing LED. However, I have noticed that if I disconnect the oscillator circuit from grond then sometimes the output LED flashe...

Thanks for the advice. Tried the code you provided and still no joy although I'm now wondering if I have a faulty resonator circuit. My PORTB.0 LED occasionally flashes if I mess with the oscillator. By "decoupling" the power supply pins do you mean connecting each pin to the power supply directly, ...

Beginner problems

I wonder if anyone has any suggestions. I've plenty of experience with 16F PICs but I'm new to 18F and Swordfish. I simply can't get my 18F4520 to even flash an LED. My programme has no problems with flashing code and reading back. I'm sure it's recieving the correct voltage and wired up correctly. ...
