@ -27,7 +27,7 @@ An Arduino IDE compatible graphics and fonts library for 32 bit processors. The
8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can used with the STM32 Nucleo 64/144 range or the UNO format ESP32 (see below for ESP32).
The library supports TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320 pixel screen. The ILI9486 RPi 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). The RPi ST7796 display is supported and is superior to the Waveshare design, it must be of the MHS-4.0 inch Display-B type.

The Waveshare 3.5 (C) TFT with 125mhz High Speed is also Supported and works at up to 80mhz SPI rate on the ESP32.
Some displays permit the internal TFT screen RAM to be read. The library supports reading from ILI9341, ST7789 and ILI9488 SPI and other supported 8 bit parallel displays. The TFT_Screen_Capture example allows full screens to be captured and sent to a PC, this is handy to create program documentation.
