Connecting the EXT3 to the Arduino Zero or M0 Pro
Scope
This configuration has been tested successfully against
This configuration may also suit other boards with the Arduino form-factor, with the size of the screen adapted to the available SRAM of the MCU. For a safe connection of the e-paper displays, please refer to EPD Handling and ESD Precaution. |
Software
On the main sketch, set the board to boardArduinoZero, corresponding to the pins defined in the hV_Configuration.h file of the ePaper_EXT3_Basic_Library (link 1, link 2).
Notes
There are multiple releases of the Arduino Zero, M0 and Arduino M0 Pro, with slight incompatibilities.
For example, D2 and D4 may be switched, SPI available only on the ICSP header, and the SERCOM number for SPI on pins 11-12-13 different. |

Hardware
Options
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. |
