Interesting application panky, especially with that "Toot" button. What is it, a single engine tug?

I have made a start on doing a PCB-based adaptor......





I will try to get one of the 9-inch TFT's in the next week or so, and by then I should have finished doing the adaptor.

Hi Grogs,

By the way, this will be useable for the 8" TFT too!

So maybe change the SilkScreen on the right-hand-side to '8"/9" TFT end....'

Oh, sure, I am just playing at the moment.
The references in red are just to help me when I do the actual track routing.

BTW, was this what you were thinking of?

The red text on the right - Yes!

In case you thought this adapter was only applicable to the 9" - This 'little' PCB will be soooo useful.

Oh, I love you too, WW....

The only think that really kept me away from using the EastRising displays, is their incompatible pin-out.

But one thing that I really like about them, is that they guarantee supply - or so they say. This means you are probably better designing with these then anything else.

Not that there seems to be any lack of the cheap displays on AliExpress or eBay....

G,

I haven't done anything about it myself yet but I would like to have a universal lcd interface board. It should include mounting holes for as many of the displays as possible as well as interfacing to as many boards as possible.

Eg. Support ILI's 2.8",3.2", 4", SSD's 4.5", 5", 7", 8", 9" on Explore 100, matherp/circuit gizmos backpack 64, some of Peter's MZ boards and possibly Armmite.

Big task but we all have to dream

panky

Great work. I also placed my order between working! and glitch!, so glad to see that it got sorted.

panky--can you lay out your pin mapping? I'd like to try a version for the Explore64 board. +1 for Armmite layout as well.

@ panky - What did you do with TE on CON1 on the 9" display? They label it as 'Tearing Effect'.
This does not correspond to any pin on the E100 that I can see, so I have left it floating at the moment, but if you used it, could you please say where it goes.

Here we are then:





If anyone sees anything obviously wrong, let me know. The board still needs a little tweak here and there on it's size and the alignment of some of the text items, so ignore those for now.

@ panky - I hope you don't think I have hijacked your idea or this thread. I did see you were going to make an adaptor, and then I saw your veroboard one, and I thought that must have been what you meant, whereas I meant a PCB version. I will discontinue posting on this thread about this board, if you would prefer.

You don't seem to have data bits 8 - 15 connected.
I think that some of Peter's firmware allows for a 16 bit interface on the 8inch.
If they are not used, having them connected on the interface wouldn't matter.

The flash chip needs to be on a separate SPI interface. I think that some of the mites use a dedicated SPI for touch and SD so it could not be accessed from Basic if not separate. For the mites that do use the same SPI, it would be no problem to link them but not through the 40 pin connector. You need access to the CS pin anyway.
