Hi there,

I got my Tinyscreen+ in the post this week, and I'm trying to put together a watchface for a prop. However this is a bit of an unusual face, and ideally the orientation of the screen could do with being portrait, rather than landscape. Is this a possbility within the tinyscreen library? I couldn't see a function that would make it easy (only flipDisplay() which is only for landscape orientation).
This would be very useful functioanlity for me and would relieve a bunch of horrible hacky behaviour I'd have to add in my actual sketch.
Thanks.

Hello,

The screen contents can be flipped as you have discovered, but it is difficult to write a portrait mode translation of the screen contents due to the pixel difference in the length and width.

I can recommend looking into the writeRemap() function of the TinyScreen library. We have rewritten this function to work with rotating a different, square screen using the following code:

Code Select Expand

uint8_t _rotateDisplay=1;

void TinyScreen::writeRemap(void){
  uint8_t remap=(1<<5)|(1<<4)|(0<<2)|(1<<1);
  if(_flipDisplay){
    remap^=((1<<4)|(1<<1));
    //Set_Display_Offset(0x00);
  }else{
    //Set_Display_Offset(0x40);
  }
  if(_rotateDisplay)
    remap^=((1<<1)|(1<<0));
  if(_mirrorDisplay)
    remap^=(1<<1);
  if(_bitDepth)
    remap|=(1<<6);
  if(_colorMode)
    remap^=(1<<2);
   
   startCommand();
   TSSPI->transfer(0xA0);//set remap
   TSSPI->transfer(remap);
   endTransfer();
}

This does not work with the TinyScreen as is, but might be a good starting point for altering the writeRemap() function.

I hope that helps!

Thanks,
Réna
