Is there a difference between the ILI9340 and ILI9340C in terms of compatability?

If not, there's a US-based eBay seller that has 9 screens in stock, with free shipping to the US*. If anyone's in a hurry. https://goo.gl/wij6Er


*and stupidly expensive shipping to Canada.

I believe that will work - looks exactly like mine. Honestly It's been hard to find any solid documentation as to the difference between ILI9340, ILI9340C and ILI9341. I'm pretty sure the 9340 and 9340C are interchangeable (I don't even see it referenced in the FBTFT source code). Even if there is a big difference between the 9340 and 9341, I think that would just be a different configuration in fbtft you'd have to use.

I'm pretty sure the 40 and the 41 are interchangable. I will do a bit of digging to see if i can find some data sheets on the different driver chips

Lost of questions and discussion around this (and availability), figured I'd start this to avoid gigantic threads where info gets lost.

Here is the screen I used:
http://www.ebay.com/itm/252135075697

The one you want is 320x240 pixels, and looks like this on the back:

just a couple of things to clear up...

the one your recommending is slightly different to the one you purchased on ebay (based on your ebay link)

the pin layout is the same, but the board is slightly different....

ebay


recommended



was your screen a ILI9340 or ILI9341, as the ebay screen is showing to be ILI9341


also, i've been searching for this screen for about 2 days now, and i have a niggly feeling the screen may now be obsolete (hopefully wrong)

as i've contacted dozens of suppliers/sellers over several portals/websites

Alibaba... the wholesale suppliers that have come back to me (still waiting on some) have all said its an old screen and no idea of restocking

aliexpress... no one has stock... the reason the price is so high is just to put of buyers... i've already contacted these seller none of them have stock... even the one selling it at $165

ebay/amazon seller based in china that are stating a delay in restocking, most probably may not end up getting them in, as there gonna go to the wholesalers and get a similar response to what i've got (could be wrong on this, but some of these sellers never have stock and only buy when orders are place... plus some feedback that i've seen is that buyers have been sent the 176x220 screen instead)


i have placed orders from a seller i found ( they havent come back to me to confirm shipment, this could also end up being out of stock)

i've also go a 2.4 screen on its way (which has been shipped ).... the pin layout is the same and there no bulky chips on the back... on my basic mock up it fits... but until you have it in hand you cant be certain

and the biggest chip on the board could be removed as it looks like its mainly for the touch part of the screen which we wont be wiring to (could be wrong on this)

2.4




we'll see in a couple of days if these sellers actually get stock, and if the place i've ordered from confirms shipment i'll post the link

so i have found some datasheets lurking on the adafruit site. they are both 233 pages long, that is the only comparison i have made so far

https://cdn-shop.adafruit.com/datasheets/ILI9341.pdf

looking at notro's github, both drivers are available, so it could be a case of adding in an extra line into the guide troubleshooting or something if the screen doesnt work with one, you can try the other

i cant see there being much of an issue getting the ILI9341 screen working, youtube has alot of videos (type in ILI9341) of ppl getting it to work with raspberry pi

i thought id seen a guide somewhere....

thats it, no more debating/pondering.... ILI9341 it is.... i actually think the 2.4 will work (size wise)... as the glimer of hope of buying a 2.2 is fading

the 2.4 is more likely to have an extra chip on the back for the touch controller (if the screen has touch) but they are pretty easy to de-solder

thanks...

i did bring this point up in an ealier post (the one with the pic of the back of the 2.4 board)

the chips not that big... but space being the issue, anything not needed is wasting space

aha, too many posts, i cant keep up

i would assume if the screen doesnt have the touch layer, it wouldnt have the chip. they dont want to waste the chips!!
