hello, i have a problem with my program. now i'm doing 8x8 led matrix display system that can display alphanumeric characters . my question is, how can i simulate my source code to display the LED. i mean how can i know either my LED is showing what i want or not. are there any special software to display led. i'm already use 8052 Simulator. but i can't find any LED display in this simulator. i hope someone can help me with my problem.. thanx...
 

Re: How to simulate 8051

I don't think there is a simulator like that, but isn't it sufficient to just monitor the state of the pins used to turn on the LED's? Their state should tell you exactly if the LEDs would be lit the way you want or not.

Labcenter Electronics have proteus(isis) software for 8051 and some cpu.And this program have led display simulator.

ROW:    MOV A,R3
        MOVC A,@A+DPTR
        MOV R2,A
        MOV P0,R2
        MOV P2,R1
        ACALL DELAY
        MOV A,R1
