Hello,

Thans for the answer.

I realize a IP, you see this in the .zip-file below.

In the NiosII I have write a simply test-code for send any data via avalon-slave bus and after read the data again. In the example I send the data= 0xF0F0F0F0, but I receive the follow:

Der gelesene Wert ist: -252645136

The code in NiosII is:

# include "NiosII_Camera_Tracking.h"

int main(void)

{

alt_u32 daten= 0xF0F0F0F0;

IOWR_IME_AVALON_XY_DETECTOR_DATA(XY_DETECTOR_BASE, daten);

printf("Der gelesene Wert ist: %i\n", IORD_IME_AVALON_XY_DETECTOR_DATA(XY_DETECTOR_BASE));

}

Could you test the IP-Block and say me what is the problem?

Thank you...
