The new library supports low cost ST7735 displays connected to an UNO,Leonardo or Mega via SPI, it is based on the Adafruit GFX library with encoded fonts to save space. It is on Github . It supports the displays advertised on eBay typically shown with a "Minions" image shown and often quoted as be…

Library has been updated to correct a bug where "black tab" displays were not correctly initialised. It now should also support the ST7735R (caveat is that I don't have one of those displays so can't test it). Latest version is on Github. Performance tests indicate it runs 2 to 10 times faster tha…

In true Ebay / Chinese style, the photos and descriptions seem to be untrue. The smaller "Minions" show a pcb printed 1.44' 128128 TFT_LCD with dimensions 30x46.5 mm. The larger "Minions" show a pcb printed 1.8' 128120 RGB TFT_LCD with dimensions 34x54 mm. Some of the Ebay listings for the larger…

Manufacturer ID: 0x7C Version ID: 0x89 Module/driver ID: 0xF0 The "Minions" display has a "green tab" screen protector but has different x,y offsets compared to another green tab display I have (which works with the standard Adafruit/Arduino IDE TFT library).

You have a ST7735S. I note that you have several different ST7735R configurations. And they seem to have very unusual pixel addressing. Where did your R displays come from? Even my oldest display has the S controller. I am impressed by your throughput. David.

The init code was copied from the Adafruit library, all I did was add the GREENTAB2 option to correct the x,y offset issue. I have 3 displays all have the same controller but they each need different configurations of offset and RGB or BGR colour order. This is just down to the way the controller dr…

Yes, my displays have different Panel settings. I have never had one with 1 or 2 pixel offset. The ST7735 has only got a limited choice of GM[ ] configurations. The ILI9163 can cater for many more different geometries. The BGR, INV, SS, GS, ... can all vary for each Panel design. If the GM[ ] se…

Latest version is on Github has been updated to improve the performance of graphics functions like drawPixel and drawLine. The change forces the compiler to inline some assembler code (which was intended in the original library but was being optimised out by the compiler to save space!)

The library has been updated again to boost performance. Latest version can be downloaded from GitHub. Report any bugs on GitHub or here. There are no pans to make further performance updates, except for bug fixes. Benchmark from the PDQ variant of the Adafruit graphics test sketch gives these p…

I am currently using 1.8" TFT with SPI communication having ST7735R driver [GREENTAB] with Adafruit GFX and ST7735 library (it has two initialization functions initR and initB. In function initR, it is mentioned that use this for REDTAB or GREENTAB) . But now the dealer says that he has ST7735S typ…

A search on eBay for OLED TFT will currently show these displays.

Also note they do not have an SD card slot.
