G,

My error, I am using the TPPEN (pin38)) on the ER 9" display as Touch Int and it is working just fine ( I had mis-labeled my diagram).

@ palcal - Hindsight is a wonderful thing. You are right, of course. But the issue is that no-one knew of the ER displays when the first TFT compatible MM's were created. Geoff and Peter used displays from eBay or AliExpress, as you would expect. Any new MM I design that needs a TFT WILL use the ER series, for precisely the reasons you and WW point out.

@ panky - Re: Pin-38, thanks a bunch. Now I know I have that pin connection correct.

I believe that would need some consideration. For something that you will only use that would be fine but I am not sure that it would be good enforcing that rule for something sold to the public.

For a start, ER panels are not that cheap when you factor in the cost of freight. In fact BuyDisplay.com prices + freight are about equal to typical EBay prices with the normally free freight - so no advantage there. Also, the wide range of options can lead newcomers to purchase something that would not work so you would have to specify EXACTLY the ER part number that is compatible with your board.

Having said that, ER is a quality manufacturer and BuyDisplay.com is a reliable supplier so that is a definite plus.

My main concern is that the ER panels are so different that all the documentation and all the experience on the Back Shed will not help a newbie who gets into trouble. So, perhaps some caution.

My input would be to simply keep the 40-pin header as is current (and as documented in the MM User Manuals), and to optionally use the adaptor board whenever you use a 7",8", or 9" ER SSD TFT.

My only concern is the 'off-set' mounting holes!

You both have a point. I jumped the gun a little there. The original concept remains. The ER are the best choice for those wanting 8" or 9" TFT's, so I guess you then get the best of both worlds.

My 9" display has arrived - that was quick. Four days from China DHL.





Cute.

Comes in a nice cardboard box, but the actual LCD module is wrapped up in bubble-wrap packaging, with no anti-static bag - a little naughty, I feel, as this device would be static sensitive. It is definitely not anti-static bubble-wrap - that is usually pink in colour.

I could see how they had wrapped it up as there was only a few layers of bubble-wrap, so I put on my anti-static strap before I unwrapped it, but yep - no anti-static bag or protection at all. I'm not super happy about that. Otherwise, VERY well packaged, and I am just waiting for the adaptor PCB's to arrive so I can try it out!

I have hooked up an E100 to the 9" ER display via one of the adaptor PCB's, and she totally dead. No response, no light from display etc. I will have to investigate. I think I might also need to set some of the jumpers on the ER board - I forgot about them, and just tried it 'Out of the box'.

I will keep the thread updated.

EDIT: Yay! Working! I forgot to swap jumpers J3 and J4 so that the display uses 1963 backlight control. That done, it sprung to life.

Good news Grogster.
My panel arrived yesterday - I used the slow-boat-cheapskate postage.
Mine was nicely wrapped including in the anti-static bag.
It also came set for backlight control by the 1963

I just need to find the inspiration to have a play with it.

I got caught the other day with that and the new Armmite screen.

My 9" just arrived, no fragile markings but packing was pretty good and it was in an antistatic bag. I'm just waiting on a Grogster adapter to arrive, luckily I ordered one as soon as they were listed.

They certainly make the 7" LCD look little

Nothing in the mail today so I knocked up an adapter in around 30 minutes, Display worked first go - touch and all. Really nice display and magic when using it via a Keyboard and inbuilt MM.basic editor when untethered from a PC.

Big thanks again to panky for having a go and trying one first
