andysworkshop / xmemtft Goto Github PK

First, I wanted to congratulate the author, Andy this is a tremendous work! thank you. Now, I'm having QVGA LCD panels from Samsung phones lying around and I would like to test xmemfft with them. I read the article in your blog https://andybrown.me.uk/2013/06/08/a-generic-16-bit-lcd-adaptor-for-the-arduino and I see you haven't tested them.
What do you think ? The board-to-board connector of this LCD panels seems very similar!
Does it worth the effort to reverse engineer them ?

Thank you in advance for any help....

There's a small bug in the rectangle demo of the graphics library. Click to see an example

The highlighted line should obviously read:

rc.Y=(rand() % tft->getYmax()/2);

The impact appears to be minor but some panels may hang when addressed beyond their supported range.

Upcoming support for the high resolution R61523 controller makes it desirable to support some larger fonts.

If FontConv is used to save a font with some characters missing in the middle then the Font class may not find all characters in the font successfully.

RESET and WR should be swapped in the documentation (code is correct)

The contributed Gpio16AccessMode needs typedefs adding to all 16-bit controllers to make it easier to use.

Add support for the Renesas R61523 controller. This controller is used in the Sony Ericsson Vivaz U5 cellphone and will feature in a reverse-engineering article on my website.
