Now working with touch :slight_smile: when i have time ill fix up the touch part i like the way you done it

When i have time i will design a new control PCB for this 7" display just as i done with the 3.2"

You appreciate my help so much, it didn't earn a single karma point? :disappointed_relieved:

ops sorry have done :slight_smile:

Appreciate it, thanks.

Hi i have a few questions i have the W25Q64FV, which is a 64Mbit SPI Serial Flash and its working but once i put images on there i haven't got space for icons so i have ordered W25Q128FVSG 128M-bit serial flash memory so that should be lots of space.
The other is about the 8-page video memory is there any way of having more than 8 pages? or is there a bigger chip to replace MD070SD for more memory. :slight_smile: hahaha
If using an SD card dose it work as fast as the Flash or is it slower?

27

First answer, 8 pages is the most, I asked that exact question!! :stuck_out_tongue:

I wrote an AWESOME library to draw images to UTFT from SD, and did I mention it is AWESOME?? :sunglasses: But funny you should ask, I didn't yet do comparative timings between SD and SPI-Flash, but seriously, even W25Q128 is not ENORMOUS....... 16MB is not lots.....

All of my time for the past 2 months has been to improve/expand the UTFT_CTE library to add additional functionality to the library but also to ADD Font IC ability to the CPLD display which Coldtears don't even offer.

I will do some comparative benchmarking between SPI and SD.

Don't hold your breath, it probably won't be this evening.

Regards,

Graham

Sounds very interesting. ... :slight_smile: have u posted the library can it be downloaded ? Would like to have a play with it. :slight_smile:
one way to have more pages is to have it load other pages in place of ones not being used in the background so u can have more then 8 only if u load pages to different menus... I did it with my code above I changed the load screen after I loading into the main code so infact I had 9 pages :slight_smile:

There you will see the kind of speeds you can expect from my library to draw from SD.

The library is called UTFT_SdRaw, and is now available on Github at GitHub - ghlawrence2000/UTFT_SdRaw: Hi speed image loading from SD/Serial for UTFT. UTFT_tinyFAT replacement.

General useage explanation here. 3.6" TFT LCD screen from eBay :-( - #76 by ghlawrence2000 - Displays - Arduino Forum

Any problems let me know and I will try to help you, there is a function in my library specifically for CPLD displays to load an image to any of the video pages.

As always, add karma if you appreciate my efforts :slight_smile:

Graham
