Hi Ben!

I know you are busy, but dare to ask
Is it possible to get the display working?

Hi Jorgen,

I've spent time on this yesterday and again today. I have made some progress but it's still not fully working. I have been able to set pixels but only from a light grey to black and not back again.

I've changed the colour from 565 to 666 format as required by the ILI9488 in SPI mode but still no joy.

I've been copying some online libraries and what I have should be working but isn't I'm now wondering if there are different versions of the driver as I've heard mention of this on a forum. Do you still have a link to where you purchased the display from?

I'll keep trying next step might be to try and get the MISO working so I can read back from the display and this will hopefully allow me to confirm the driver IC I'm dealing with.

Hi Ben!

Well ok, tricky display, I though it was almost similar with few change to the Ili9341 If I use the ILI9341 display with Ili9488 component SPI the Ili9341 work, but not 100%

Unfortunately I can´t remember where I bougth the display, I think it was on Ebay somewhere.

Edit, found it here: https://www.ebay.de/itm/1pc-3-5-Zoll-48 ... 2411b818ed

Maybe mehmert can help, where do you buy yours?

Hi BEN
how are you today?Were you able to launch the lcd?i waiting good news from you?

Hi BEN ... is there any new information about this component?

Hello,

I did have another go on Friday and over the weekend. I went through the register initialisers from the library I was using and compared them to the datasheet and they were all over the place in terms of either not matching up the correct number of parameter bytes or calling functions that weren't there, on my version of the datasheet anyway. So I've stripped out everything that is wrong and I'll try and move forward using defaults and switching individual settings on and off to see if it makes a difference.

I also implemented the register readback so I can monitor the setup of the LCD once everything has been initialised. This should hopefully allow me to play with the settings until I stumble onto a setup that works.

Hopefully I'll get more time on it tomorrow.

Wow Ben. Thank´s for information and your work I am not home before thursday, hopefully to test, look forward.
