Has anybody get the Character LCD component run a 4x20 LCD display?
In the CAN example the print on row 3 but it not working, nothing prints on the display.
I have try some different models, without success.
Are there some parameters I need to set, that I overlook?
If you can print to line 1 and 2, but not line 3 and 4 then you may have an initialization problem.
4 Line Character displays are normally made as 2, 2-line displays, and each "display" requires its own initialization.
