UTFT_SdRaw Manual

Other Hardware Displays

Hi colleagues,

Working on Arduino project with a TFT touch screen I try to display some pictures from the SD card.

The tinyfat library does not work at all and it is quite restrictive.

For this reason I try to work with UTFT_SdRaw GitHub - ghlawrence2000/UTFT_SdRaw: Hi speed image loading from SD/Serial for UTFT. UTFT_tinyFAT replacement.

Does anyone found a manual of the functions ?

I made it work, but the picture have inversed colors...

I am still a DIY beginner informatic, so for me this library is quite unclear about its functions and its parameters.

Graham, creator of this library, happens to e on the forum sometimes, see here for example. If yu need help, you can wait until he sees you post or send him a PM

I have the same problem ..

I found these comments in one the examples of the library:

// loadS(port, x, y, xsize, ysize, buffermultiplier, invert colours)
// port can be Serial / SerialUSB
// x , y are the display coordinates
// xsize , ysize are the expected image dimensions
// buffer multiplier is used to potentially increase speed a little :-
// total buffer size = buffermultiplier * 2 * xsize
// invert colours is used to swap the MSB/LSB if colour appears wrong

When I put 1 in the (invert colours) place the colors are changed but the image is distorted !
