The display had a protective film with a green tab ?
Oh I saw. It is blue !
Mmm.. Protective film for Display ST7735 and ST7735S is normal black or green. Blue is not right !?
Good morning Rolf. Thank you very much for your help, it almost happened - the beginning is shifted and the number of pixels is inaccurate.
Hello Alex.
Here is a new Jeannie Firmware 2.21 ST7735S version. I hope your display problem is solved 
Change display code in the ST7735_t3.cpp file
// Initialization for ST7735R screens (green or red tabs) void ST7735\_t3::initR(uint8\_t options) { commonInit(Rcmd1); if (options == INITR\_GREENTAB) { commandList(Rcmd2green); \_colstart = 2; \_rowstart = 1; } else if(options == INITR\_144GREENTAB) { \_screenHeight = ST7735\_TFTHEIGHT\_144; commandList(Rcmd2green144); \_colstart = 2; \_rowstart = 3; } else if(options == INITR\_144GREENTAB\_OFFSET) { \_screenHeight = ST7735\_TFTHEIGHT\_144; commandList(Rcmd2green144); \_colstart = 0; \_rowstart = 32; } else if(options == INITR\_MINI160x80) { \_screenHeight = ST7735\_TFTHEIGHT\_160; \_screenWidth = ST7735\_TFTWIDTH\_80; commandList(Rcmd2green160x80); \_colstart = 24; \_rowstart = 0; } else { // \_colstart, \_rowstart left at default '0' values commandList(Rcmd2red); } commandList(Rcmd3); // if black or mini, change MADCTL color filter if ((options == INITR\_BLACKTAB)|| (options == INITR\_MINI160x80)){ writecommand(ST7735\_MADCTL); writedata\_last(0xC0); \_colstart = -2;// only for ST7735S \_rowstart = -1;// only for ST7735S } tabcolor = options; setRotation(0); }

Thank you very much. But I can’t compile the project - it constantly gives an error SD
I have send you an email with hex-File
Rolf, a huge thank you for your responsiveness and ability to help. If you are interested in the ppt I developed, I can download (only) gerber files for you.
I wish you a lot of fun with Jeannie. Large DIY block for the Jeannie and Updates..

There is a new case for the Jeannie..

With wooden side panel looks even better..
Nice and finished. But I have a slightly different arrangement of controls and indications. But this design is good, I’ll take it for the basics, thanks.
I’m building wooden side panels for Jeannie.
My beautiful office has been transformed into a carpentry workshop. And who cleans up afterwards.. (:
Jeannie with self-made wooden side panels..
Очень красиво и профессионально! А еще я хочу представить окончательную версию вашего гениального устройства в моей одноплатной версии.
Very nice and professional! I also want to present the final version of your ingenious device in my single board version.
