    Re: Les's ILI9325 Wiki code

    Great news Charlie. By the way I spotted a reference in Silicon Chip that suggested that when running two SPI devices from the same MSSP that it was necessary to reset the MSSP when changing chip...

    Re: Proton PIC BASIC Compiler - ADS7846 TouchScreen Controller Library

    Yes Flosi, and they take up a lot of space too. So I just include the fonts I need and even then keep them to a minimum of two.
    I've got the keypad working nicely.

    Re: Les's ILI9325 Wiki code

    All noted Charlie,
    What I'll do is get touch going first with Les's code and light LEDs on the Amicus. Then I'll try switching the CS, then add the graphics.
    On phone at present. Bowls tomorrow. ...

    Re: Proton PIC BASIC Compiler - ADS7846 TouchScreen Controller Library

    Charlie, I'm beginning to wonder if your displays without the chip supplied required something other than just the chip. I will take over the experimenting again as my displays came with the chip and...

    Re: Les's ILI9325 Wiki code

    Les, thanks for the further explanation on the use of '$define cConstant" and 'Symbol'. I now fully understand.
    Re the 'hte' that is not so unusual. I do the same with 'the' and some other words....

    Re: Les's ILI9325 Wiki code

    Thanks for the explanation Les, it was really helpful as were the earlier tips on using Touch.
    I am a bit inconsistent with my naming strategy and will in future bring my code into line with your...

    Re: Les's ILI9325 Wiki code

    In Les's code he uses:
    $define ADS_SDO_Pin PORTC.5 ' SPI SDO to ADS7846 DIN (Uses the MSSP1 peripheral)
    $define ADS_SDI_Pin PORTC.4 ' SPI SDI from ADS7846...

    Re: Les's ILI9325 Wiki code

    Greetings all,
    Well this touch stuff is proving hard.
    Two problems
    1) the code on the WIKI and Forum of Les's Touch control has the leading %0 problem. I reckon I can guess my way around that.
    2)...

    Re: Les's ILI9325 Wiki code

    Thanks for the reply Flosi.
    I might not have been clear that as well as running the touch I want to run the display from SPI. I know that will have speed problems.

    Re: Les's ILI9325 Wiki code

    I'm waiting on my ILI9325 2.4" display. For a development of a project I want to use the graphic display with touch.
    Speed is not important, it will have a touch numeric keypad and a line or two of...

    Re: Les's ILI9325 Wiki code

    The Silicon Chip Backpack was a bit more sophisticated. It used a pic32 programmed with a BASIC interpreter. Programs could be loaded serially using any old serial editor.

    Re: Les's ILI9325 Wiki code

    Hi Charlie,
    Many of those with different sizes share a ILI9325. So I was hoping it was just the size of the pixels.
    I'm hoping to produce a PDS equivalent of the LCD BackPak (Silicon chip articles)...

    Re: Les's ILI9325 Wiki code

    G'day charlie,
    Do I read you correctly, you'll produce a list of tested graphic displays, their driver chips and a corresponding list of the Proton drivers that work with them?

    That would be very...

    Re: Les's ILI9325 Wiki code

    Charlie, in some code I have for controlling an audio recorder I set that pin low before sending a command and then set it high after each command. Basically a chip select function I guess.

    Re: Les's ILI9325 Wiki code

    Les, thanks for the link to the display. As soon as I get home I'll buy one and use a p24.
    The good thing is I'll be able to experiment on Charlie's coat tails.

    Thanks Charlie and Flosi,
    I looked at the link and the display connections look complicated, does it have a flexible connector?
    I think SPI would be better for my applications as I seem to always...

    Re: Les's ILI9325 Wiki code

    Charlie, just out of curiosity, what kind of display is it?
    I've successfully used the 0.96inch displays and they are very good all things considered but I've been tempted to experiment with 2.4 or...
