HCDisplay Arduino library for Hobby Components Displays

[andrew]

The library for 12864B Parallel/Serial Graphic LCD Module (SKU: HCMODU0032) appears to be missing.

I get the following error when compiling...

.... libraries\HCDisplay/HCDisplay.h:63:3: error: #error "No display defined!"
63 | #error "No display defined!"
| ^~~~~

You need to tell the library which display you are using by uncommenting it in the options.h file.

To do this, locate the HCDisplay library folder. If you are using Windows this should be located in My Documents\Arduino\libraries\ folder.

Inside the HCDisplay folder you should find the Options.h file. Open this in a text editor. Note that if you're using Windows, don't use the built-in windows notepad as it gets the formatting wrong. Instead use something like notepad++.

In the Options.h file make sure that all the display options are commented out (with a //) except the one for your display. For your display the file should then look like this:

Whilst you're editing the file you can also comment out any fonts you're not using to save some program memory.

Once you have edited the file save it and then try compiling your sketch again.
