Connecting the EXT3 to the Teensy 3
This configuration has been tested successfully against
Large screens 9.7" and 12.2" require panelCSS to be defined and connected. Please note they require large RAM only provided by the Teensy 3.5 and 3.6 boards.
If the second memory is populated on the EXT3 board, flashCSS needs to be defined and connected. The library will keep flashCSS HIGH to avoid any interferences with the other devices connected to the SPI bus.
