Address in the C program

JBaben over 1 year ago

Hello ,

I would like to control an LCD display with a microcontroller AT89C51RC2.

The hardware address of the LC display is: “0xF800”.

With the assembler code:

1
2
3
LCD_ADR EQU  0F800H      ; Basisadresse LCD
MOV  DPTR,#LCD_ADR
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

LCD_ADR EQU  0F800H      ; Basisadresse LCD

MOV  DPTR,#LCD_ADR

I can go to the relevant address.

But how can I implement this in the C program.

My compiler: Keil-C with C51.exe

Kind Regards

Juergen B.
