Is it possible to change the smiling-Cleo splash screen or make it become blank until the arduino application takes over?

Hello DSV,

Sorry but we don't have a current solution but we will investigate and get back to you.

thanks CleOSupport

Thanks, I do hope there are some solution to it. I'm evaluating the screen for a small volume industrial application and to most part Cleo is a really useful product that saves a lot of development time. However since the device will be turned on and off at every use, the cleo splash-picture is causing some user questions. Having the firmware version shown briefly is fine the cleo picture looks a bit too toy:ish in this case.

You could use the FT8xx directly, Riverdi for example has a nice variety of TFTs:

I like the RVT70UQFNWC0x, it has a nice flat glas surface, just cut a hole in the case, glue it on with the supplied sticky tape, done, looking good.

Thanks for the tip Rudolph. I've been looking for something like that but Riverdi has a relatively low resolution (320x240) compared to Cleo (480x320) on the same size of display. 3.5" is pretty much the sweet spot size but I need the higher res.
Any chance you have another suggestion? I relatively new in this and don't really know the market.

Unfortunately there is not much else that is ready-to-use - and I am looking in the oposite direction, bigger than 7". :-)
HAOYU has a few but all bigger and the smallest with FT811 is 5".
4D Systems has a single 4.3" with FT800.
Gameduino2 is 4.3" with FT800.

FTDI has the ME810A-HV35R which is 3.5" and 480x320 but only has resistive touch, well, like the CleO.

On the other hand, have you really checked 320x240 3.5" TFTs?
I started with a VM800B35A and found the 4 pixel/mm hardly to be a limitation but pretty much perfect
Combined with the better quality of the RVT3.5B320240CFWC81 for example with cap-touch I would not mind the "low" resolution.
Well, okay I would not be pleased with the FT801 anymore but it can be replaced with the FT811. :-)

Also, designing a custom board for your TFT could be an option, this could as a benefit also make the whole system smaller and more robust.
Unfortunately FTDI and now Bridgetek do not offer much support for such an endeavour.
There are no example layouts available, "only" schematics.
The design-support is limited to a FT800 schematic symbol and footprints, nothing at all after that initial effort.

https://designcontent.live.altium.com/#UnifiedComponentDetail/FTDI_Embedded_Video_Engine_(EVE)

Although the page lists everything up to FT813, the archive you receive is from 2013 and does only contain FT800.
Yes, I just download it to check.

Okay, that level of support is not to be expected but I would apreciate it.

Also there are close to no updates to the existing documentation although for example the "FT81x Series Programmers Guide" contains typos and misinformation that I reported to FTDI several months ago.
Plus no updates to for example EVE Screen Designer or to EVE Screen Editor (which I prefer).

I still wonder what Bridgetek is about, from an outside perspective, there is not much going on with them.

Hint to FTDI/Bridgetek, a FT82x with LVDS and higher resolution would be nice. :-)
Additionally nice would a new VERTEX-command that does not require to shift bits around, dynamically pushing objects around does eat up a lot of computrons now, especially on 8-bit controllers.
Just make it a co-prozessor command with the x/y coordinates supplied as arguments.

Hello DSV,

Could you tell us which version of the CleO firmware and CleO software package you are running?

Also, is the splash screen on your module showing up after programming or on every start-up before the Arduino app begins?

Regards, CleOSupport

@Rudolph
I've come to pretty much the same conclusions. Designing a new board is out of scope for this project and 320x240 should be worth a try before rejecting. However 4d system seem to have a 3.5" display with both resistive and capacitive touch at 320x480. Doesn't support SPI slave though so we'll need to switch to serial but that shouldn't´t be a major problem.
Believe resistive touch is the better choice in this case as its less prone to accidentally trigger while fiddling around with the device.

@CleOSupport
I've tried both firmware 2.1.0 and 1.1.1 (which I failed to upgrade to 2.1.0, see separate thread). Not quite sure about software package but at least the display with 2.1.0 was installed along with its corresponding package.
It shows up at every start-up. I've set the display to clear in the first part of Arduino setup but the splash is still briefly visible during power up. When performing a hard reset (reset button) while still being powered this happens so fast that I can't see the cleo-splash.

Hi DSV,

Could we ask you to email us at support.emea@brtchip.com with details of your requirements for the EVE module and we will get back to you with some suggestions.

Best Regards, CleOSupport

@DSV

Well, 4D Systems may have other options available but that would be without FT8xx and I would not recommend that. :-)
