$LCDRS

Top  Previous  Next

Action

Instruct the compiler to generate code for 8-bit LCD displays attached to the data bus.

 

 

Syntax

$LCDRS = [&H]address

 

 

Remarks

Address

The address where must be written to, to enable the LCD display and the RS of the LCD.

The db0-db7 lines of the LCD must be connected to the data lines D0-D7.

The RS line of the LCD must be connected to the address line A0 by default.

When it is connected to another address line you can specify $LCDRS

On systems with external RAM/ROM it makes more sense to attach the LCD to the data bus. With an address decoder you can select the LCD display.

$lcdrs = &H8002       'writing to this address will make the RS line of the LCD high.
