Connecting the EXT3 to the LaunchPad MSP432P401R
This configuration has been tested successfully against
On the main sketch, set the board to boardLaunchPad, corresponding to the pins defined in the hV_Configuration.h file of the ePaper_EXT3_Basic_Library (link 1, link 2).
Always check the LaunchPad provides enough SRAM for the frame-buffer of the screen.
Some LaunchPads are incompatible with this configuration, as GPIOs are already used by included sensors. Those LaunchPads require either adaptating the GPIOs of this configuration or using a specific option.
This is the case for the LaunchPad CC1352R and LPSTK-CC1352R: please refer to Connecting the EXT3 to the LaunchPad and LPSTK CC1352R.
Large screens 9.7" and 12.2" require panelCSS to be defined and connected.
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.
