TFT rotation and Touch coordinates #6

Closed maitredede closed 5 years ago

maitredede commented 8 years ago

Hi,

When using the paint sample, I can see that screen rotation is not the same that touch rotation : I touch horizontaly (left to right), it draws verticaly (bottom to top). If I tft.setRotation(1), coords are good.

How can I have touch and screen rotation have matching coords ?

Thanks.

Hi,

In mine TFTs I need invert the coords. Can be in your case it not necessary.

Please modify the SPFD5408_TouchScreen, line 159:

before:

//return TSPoint(x, y, z);

// *\ SPFD5408 change -- Begin // SPFD5408 change, because Y coordinate is inverted in this controller return TSPoint(x, 1023 - y, z); // -- End

after:

return TSPoint(x, y, z);

// *\ SPFD5408 change -- Begin // SPFD5408 change, because Y coordinate is inverted in this controller //return TSPoint(x, 1023 - y, z); // -- End
