Hello Erel,

to use a ST7735s 0.96" TFT Display with rAdafruit_ST7735 i must have add a special Initialization.

I'm sorry but i did not know how to do this.
My knowledge of creating libs is very limited.
Can you pls explain me how to do this ?

thx
Michael

Arduino:
// Initialization for ST7735R screens (green or red tabs)
void Adafruit_ST7735::initR(uint8_t options) {
   
  commonInit(Rcmd1);
  if(options == INITR_GREENTAB) {
    commandList(Rcmd2green);
    colstart = 2;
    rowstart = 1;
  } else if(options == INITR_144GREENTAB) {
    _height = ST7735_TFTHEIGHT_128;
    _width = ST7735_TFTWIDTH_128;
    commandList(Rcmd2green144);
    colstart = 2;
    rowstart = 3;
  } else if(options == INITR_MINI160x80) {
    _height = ST7735_TFTHEIGHT_160;
    _width = ST7735_TFTWIDTH_80;
    commandList(Rcmd2green160x80);
    colstart = 24;
    rowstart = 0;
  } else {
    // colstart, rowstart left at default '0' values
    commandList(Rcmd2red);
  }
  commandList(Rcmd3);

  // if black, change MADCTL color filter
  if ((options == INITR_BLACKTAB) || (options == INITR_MINI160x80)) {
    writecommand(ST7735_MADCTL);
    writedata(0xC0);
  }

  tabcolor = options;

  setRotation(0);
}

this is line 385 to 422 in Adafruit_ST7735.ccp
