Possible to turn on/off individual points?

[hems]

Hello i would like to print some custom "dor, indtead of characters..

So i could draw some waves in "low resolution" on my LCD, is there such a funcrion that i could send X/Y for the "dit" instead of a string?

The HD44780 doesn't support turning individual points on and off.

The HD44780 does support up to 8 user defined characters but the lcd package doesn't have an API for using this functionality. The lcd package could be extended to support user defined characters but 8 characters are almost certainly not enough for drawing low resolution waves.

oh, 8 user defined caracters would actually be perfect! because the waves are actually REALLY low resolution.

so basically 1 character having just the bottom line filled, another with the bottom 2 lines filled, another with 3 lines filled would be perfect.

Would it be easy to add this to the node.js package?
