Visual TFT - FT800 rotating screen 180 deg.

[qwepoi]

Hi

I'm trying to use VisualTFT software with ft800 chip . In project setting I have a rotate option but changing that from 0 to 180 deg doesn't change the angle ?
How to design screen in vertical orientation ?

cheers

Hello,

FT800 chip supports only 180deg display rotation.
Changing the orientation from landscape to portrait is not supported by FT800.

Best regards.

Hey Guys,

This is unfortunate that the Eve does not support portrait orientation, just right-side-up and upside-down (0 deg. and 180 deg.).
But I have yet to come up with a need for portrait orientation, the Landscape orientation offers plenty of screen area to work with, so far.

If doing something like a cell phone project, I can see there being a big issue for no portrait setting.

There should have been more information in products description to alert potential purchasers of this limitation I feel though.
(to prevent angry customers after they purchase and find out it can not do portrait orientation.)

Truthfully, I had thought the 180 deg. setting was a typo, not factual operation setting until I read this posted question and reply.
I was going to ask the same thing eventually too.

Just a thought, Robert.

Well, I will call it disaster . If any one of you thinking to buy it , please think again. I have buy this unit just to get full support from visualTFT . Touch screen works fine , but no screen rotation are supported and the quality of the LCD screen is just rubbish , I'm talking here about viewing angles .

I have just received the connect EVE and I confirm the quality of the display is terrible in term of angle view.

Can we just draw the image itself in portrait using the VTFT?

so it still can be viewed as portrait!

Hi Darmandran,

I believe you can show graphic images from a paint program oriented in portrait angle, but all built in objects and gadgets for the EVE will only have 0 and 180 degree viewing angles available.

Even additional fonts that are not original to the EVE will only be displayed as landscape unless custom made to appear like portrait
(90 degrees rotated).

Best regards, Robert.

Thanks, been testing it... currently i having issue with the static image. when i use the VTFT image in static than i can see the image in FT800, but if i choose static false , i don't get to see the image ....

Hi Darmandran,

Did you get the image static/not static problem sorted out?

The main difference I can think of between the setting of this is that a static setting places the image data as a constant array of numerical values in program memory (ROM), where you can see the data in code (in projects objects file), and if dynamic setting used - the data needs to be loaded into an array variable assigned for the image data from either code or a resource file that has been created for the application.

Just curious if you got it solved yet? Robert.

Sorry
the AN_240 FT800 From the Ground Up is clear .. see section 2.2
https://www.ftdichip.com/Support/Docume ... und_Up.pdf

"Rectangular displays may be orientated as landscape (the longer dimension is in the X direction)
or portrait (the longer dimension in the Y direction). "

Why you say it is not possible?
