Mr. Andy Neil ,
i can't understand why have you given this type of reply? I have read the c51.pdf (keil uv2). i changed the memory model from the options of "Target1". the program was compiled successfully. but when i burn that hex file on p89c51rd2bn, nothing was shown on the lcd. i have also tried the #pragma large but nothing appeared on lcd. |
