Remarks

This initialization function extends the standard initialization by DOGM162 specific initialization. This function has to be called before the display can be used.

History:

V2.0.1 05.11.2014 Michael Riedel

• added functions for better lcd-usage from script (p. 1-122)

V2.0.0 Ferdinand Englberger

• comments in english
• Remove all functions, but initialization function
• uses component register interface, instead of own access function.
• uses a base parameter to identify lcd.

V1.1 25.06.2012 Johann Mayr

• Initial version

V1.0 20.12.2011 Johann Mayr
