Inkplate 6COLOR compilation errors with E_INK_WIDTH and MCP23017_EXT_ADDR

Customer:

I’ve followed the setup guide to connect my Inkplate 6 to my PC. I tried using the Inkplate UI Designer to add a single bitmap image and copy it to the board. I’m getting several compilation errors:

uint8_t pixelBuffer[E_INK_WIDTH * 4 + 5];

Soldered Support:

The documentation was out of date. You need to download and install the board definition from:
https://github.com/e-radionicacom/Dasduino-Board-Definitions-for-Arduino-IDE/raw/dev/package_Dasduino_Boards_index.json

Also download the Inkplate library from:
https://github.com/SolderedElectronics/Inkplate-Arduino-library/tree/PCAL-Support

Unzip the downloaded library and paste it to the Arduino libraries folder. Before uploading, make sure you’ve selected the “Soldered Inkplate6” board if you have the purple one.

After trying that, I’m now getting linker errors:

Soldered Support:

You have multiple old installations that need to be cleaned up. First, remove “Inkplate Boards” from Arduino’s board manager and close the Arduino IDE.

When closed, delete these files and folders:

The Dasduino-Board-Definition folder from your Arduino15 packages directory
The Inkplate_Boards folder from your Arduino15 packages directory
The Inkplate_core folder from your Arduino15 packages directory
The package_Dasduino .json file from your Arduino15 directory

Also delete the old Inkplate libraries you don’t use from your Arduino libraries folder (Inkplate-Arduino-library-master and InkplateLibrary).

Then rename “Inkplate-Arduino-library-PCAL-Support” to “Inkplate-Arduino-library”.

After that, open Arduino IDE and add this link to your preferences:
https://github.com/SolderedElectronics/Dasduino-Board-Definitions-for-Arduino-IDE/raw/master/package_Dasduino_Boards_index.json

Then download the Inkplate boards from the board manager.

After doing that, I’m still getting the same linker errors:

Soldered Support:

What example are you trying to compile? Try opening any Inkplate example and compiling that. This error typically occurs when you’re compiling an empty sketch or your sketch doesn’t have setup() and loop() functions defined.

See these related Arduino Forum discussions:

I’m trying to copy a JPG onto the board. I’ve based my code on an example. When I upload the code to the board, it just cycles through different coloured screens and doesn’t display the image.

Soldered Support:

The Inkplate 6COLOR needs time to draw an image on the screen, approximately 15 seconds. E-paper displays are slow to draw, especially the Inkplate 6COLOR, so they’re intended for data and pictures that don’t change frequently. Just wait a moment and your image should appear on the screen.
