Hi,
My name is Thomas Jespersen.

Lets start from the beginning, or you know, from where I got my keen interest in electronics:
I started programming in Visual Basic 6 when I was 8, and then at an age of 13 my interest in electronics began. At my 13 years birthday I got my first solderiron, and some Velleman kits.

Then at my 14 years birthday I got my first PIC programmer, from Velleman. I made a code in PIC Basic Pro, programmed it, and tested it on my breadboard – it was a very exciting moment.

In the spring of 2008 I bought my first real “Development Kit” from mikroElektronika, and I have never regretted that I’ve bought it.

Later on I’ve bought many different addons, other development kits, or made my own circuits – and that’s what I’m going to show you own this blog!

 
Best Regards
Thomas Jespersen

    Hi,

    I hope you dont mind me asking, and will be able to help me!

    I notice you have had success with the PIC PAL Library from Bruno @ Micro Examples, I haven’t tried constructing this project yet, I have, however, tried constructing the PIC PAL Super Imposer project, and I have not been able to get it to work, I get a lot of “camera roll”, I was just wondering if you had managed to get it to work at all, or know how to use the PIC PAL as an overlay device?

    Regards

    Hi Wlksey.
    About the OSD (Super Imposer project), I tried that before making the other project, as I thought it would be easier, as it did only require a PIC12F (8-pin).
    But I was wrong… I connected it as descriped, but nothing happened! After alot of testing, rewiring and code-debugging, I concluded that the problem maybe had something to do with the input signal! So I started making the “larger project”, which made the signal itself…

    So no, I never got the OSD to work – so no, I’m sorry, I don’t know how to use the PIC PAL library as an overlay device, which is OSD!

    Best Regards

    Ok, thank you for replying.

    I was having a look at the library, if I dont “clear” the screen, connect the input to the output would that work as an overlay or do you think it would break the signal?

    I had to change the CLIP_LEVEL from 300-0 for the OSD to display anything, but the sync is all jittery!

    Do you have any information about using an LM1881 with a PIC as a OSD at all?

    Regards

    First, I haven’t worked with the ML1881, so I can’t help you there…
    I don’t think connecting the Input and the output would break the signal – but I don’t think there will be any overlay… The input will be the same as the output!

    Hi Thomas ,,,

    I really liked that board with 3.5″ TFT ,, Just want to know from where you got the datasheet of ILI9919 ??

    Thanks

    Hi Maan.
    After alot of late hours I finally figured out that the controller which returns 9919 when you ask it for it’s product ID, is the controller: SSD2119
    You can find the datasheet here: http://www.crystalfontz.com/controllers/SSD2119.pdf

    OKayyyyyyyyyyyyy ….

    I have bought the same display like yours from CrystakFontz and developed the GUI,s an year ago ,, see the links …

    hi thomas;
    i have a problem with my development kit(mcbstm32c) and its lcd.i want to load pictures and show it, but i couldnt find a suitable converter.Could you send the converter, you mentioned other pages written on vb.net.

    thanks…

    I dont’ know the MCBSTM32C, but if it is a 320×240 pixel color display, then you can use my converter.
    You can download it here: http://elec.tkjweb.dk/BinaryImageCreator.zip – remember, this is only a beta version, so bugs can occour.
    You also have to quit and start (restart) the program everytime you have to convert another picture – you can’t convert pictures in a row, just by selecting another!

    Thanks for reply Thomas.
    I used 5 or 6 converter including your converter but none of them bring me a conclusion.I am using keil’s library files over their sample lcd projects and changing their bitmap’s c code with my c code created by the converters,when i downloaded and started to kit , i couldnt see the true bitmap.The images arent logical.Also keil doesnt support a suitable converter to their samples,i dont know how i can find

    Hi Mehmet.
    I really don’t know, as I don’t know the screen on that Keil Development board.
    If you could give me more specifications about that, then I might able to help you.

    Dear Tomas,
    I am a student at university and I am working on a project in which I need to display icons & menus on TFT LCD. I am using the STM3210E-Eval board with an STM32F103ZE microcontrollar.
    I’m runnig the demonstration software for the STM3210E-Eval. I displayed the main menu & the icons and now I need to change these icons with some other icons according to my application to load them after that to the Internal Flash.
    Can you please help me with this ??
    Best Regards,

    Dear Mariem.
    I haven’t got a STM3210E-Eval board myself, though I have looked on the code.
    If you are going to have the icons saved in the internal flash, then it’s easy. You have to make a constant array with the color information!
    If you need to have the icons in the external flash, then you probably have to make an empty project with different vectors moved, and then make a constant array in there – but I don’t know!

    Best Regards

    Dear Thomas,
    I’m building a Daft Punk-esque Disco Table, and I’ve been running into some issues (because I’m just getting into this whole world) it’s essentially a 5×5 Dot matrix, but each pixel is made up of 4 LEDs. I thought your USB controlled board was a great start, but could you help me with the rest?

    @Will
    Take a look at this schematic: http://www.mikrocontroller.net/attachment/44489/ledmatrix5×5.png
    This is what you will have to do, except that you will have 4 LEDs connected together for every single LED on the schematic.
