 The library supports TFT displays designed for the Raspberry Pi that are based on a ILI9486 driver chip with a 480 x 320 pixel screen. This display must be of the Waveshare design and use a 16 bit serial interface based on the 74HC04, 74HC4040 and 2 x 74HC4094 logic chips. A modification to these displays is possible (see mod image in Tools folder) to make many graphics functions much faster (e.g. 23ms to clear the screen, 1.2ms to draw a 72 pixel high numeral).
 
+Some displays permit the internal TFT screen RAM to be read. The library supports reading from ILI9341, ST7789 and ILI9488 SPI displays for the ESP32 and ESP8266. The 8 bit parallel displays used with the ESP32 can usually can be read too. The TFT_Screen_Capture example allows full screens to be captured and sent to a PC, this is handy to create program documentation.
+
 Support has been added recently for Waveshare 2 and 3 colour ePaper displays using full frame buffers. This addition is currently relatively immature and thus only one example has been provided. Further examples will be added soon.
 
 The library includes a "Sprite" class, this enables flicker free updates of complex graphics. Direct writes to the TFT with graphics functions are still available, so existing sketches do not need to be changed.
