Problem in using AT89C52

NORE NORE

Hi there,

i have problem in using AT89C52. When i used this ic, my board is not working at retrieving data and sending data to pc. Previously i have done using 8051 in demoboard and it works fine.

For this AT89C52 i have included the library file <AT89x52> but still my board is not working , why? . i have enabled the "use on chip rom" and have connected the EA pin to logic high. but i do observe that there is no oscillation signal at pin 18. Is there any setting that i have to set for this AT89C52??

Please help me on this problem. Your help is much appreciated.

Thanks.
Nore
