Hi.
i wrote this code sample in mikroc pro.

void main() {
ADCON0 = 0;
ADCON1 = 0;
trisb=0;
EEPROM_Write(0x80, 124);
for(i = 0; i < 32; i++) {
portb=EEPROM_Read(0x80+i);
delay_ms(1000);
}


}

it's working well in realtime. But in proteus giving error code. can you help


what can i do for this
 

Hi,

Apparently, there is a bug in Proteus or MikroC EEPROM library. There are several issues similar to you own when using the EEPROM library in Proteus, but perform as expected when implemented in real hardware, posted in several forums. However, custom routines written without the MikroC EEPROM library, seem to perform without error in Proteus, very interesting.

I managed to have the simulation run successfully with your code by change the "Data EEPROM write delay" under Advanced Properties to any value in nanoseconds, however any value in milliseconds or microseconds produces similar errors.

I have attached the Proteus file so that you can see the property setting.

Thanks BigDog. What did you change in diagram..? where can i found Advanced Properties..?
 

if you double click the component in proteus you can open the edit component dialog, you will see an advance properties drop down menu where you can select the "data EEPROM write delay" and change the value or check the edit properties as text checkbox and change the value of "EPR_WRITEDATA_DELAY" property

Here is screenshot of the Edit Properties Dialog Box of a PIC:

Click on the Advanced Properties Drop Down Menu, which has the "Generate Q Clock on CLKOUT Pin?" shown in the screenshot.

And select "Data EEPROM write delay" properties, you will then see I have changed the value to 1000ns.
