Generic
|
|
|
|
Most LCD functions are specific for which output we work with, due to the
|
|
huge differences.

|
|
|

|
lcd_clear_display() - clear the whole display
|
|
lcd_backlight(on) - set backlight on/off
|
|
|
|
Recorder
|
|
|
|
All the functions operate on a display buffer. You make the buffer get
|
|
shown on screen by calling lcd_update().
|
|
|
|
lcd_update() update the LCD according to the internal buffer.
|
|
