 - back: a LED backlight used by some older devices (ST7735). It is PWM controlled for brightness
 - VFlip and HFlip are optional can be used to change display orientation
+- rotate: for non-square *drivers*, move to portrait mode. Note that *width* and *height* must be inverted then
 - Default speed is 8000000 (8MHz) but SPI can work up to 26MHz or even 40MHz
 - SH1106 is 128x64 monochrome I2C/SPI [here]((https://www.waveshare.com/wiki/1.3inch_OLED_HAT))
 - SSD1306 is 128x32 monochrome I2C/SPI [here](https://www.buydisplay.com/i2c-blue-0-91-inch-oled-display-module-128x32-arduino-raspberry-pi)

 - SSD1327 is 256x64 grayscale 16-levels SPI in multiple sizes [here](https://www.buydisplay.com/oled-display/oled-display-module?resolution=159) - it is very nice
 - SSD1675 is an e-ink paper and is experimental as e-ink is really not suitable for LMS du to its very low refresh rate
 - ST7735 is a 128x160 65k color SPI [here](https://www.waveshare.com/product/displays/lcd-oled/lcd-oled-3/1.8inch-lcd-module.htm). This needs a backlight control

+- ST7789 is a 240x320 65k (262k not enabled) color SPI [here](https://www.waveshare.com/product/displays/lcd-oled/lcd-oled-3/2inch-lcd-module.htm). It also exist with 240x240 displays. See **rotate** for use in portrait mode
 
 To use the display on LMS, add repository https://raw.githubusercontent.com/sle118/squeezelite-esp32/master/plugin/repo.xml. You will then be able to tweak how the vu-meter and spectrum analyzer are displayed, as well as size of artwork. You can also install the excellent plugin "Music Information Screen" which is super useful to tweak the layout.
