LCD Support #21

Open benpye opened 8 years ago

benpye commented 8 years ago

Looking at the aprinter code, there appears to be no way to output data to an LCD for local monitoring? This would be a useful feature to have, though given the range of LCDs avaliable, not too sure how it would best be done.

Hey, Yes, there is no support for displays now, and I'm currently working on other things. If you would like to add support, it should be in form of a new Module (see aprinter/printer/modules). You would also need to integrate the module into the configuration/build-system by adding stuff to config_system/generator/generate.py and config_system/gui/aprinter_config_editor.py. The module would need to get the status information for display from the appropriate classes, particularly PrinterMain (general and axis-related information) and AuxControlModule (heaters and fans). Some changes will be needed in these classes to expose this information, and also to be able to access the AuxControlModule itself.

I can provide furhter assistance if you're willing to work on this.

By the way, I would personally start with supporting the common character-based displays (HD44780 stuff), rather than anything more complex. So that it would work on pretty much all platforms.

That sounds like a good plan. I will try and look at it sometime as it sounds like a fun project.
