Programming AT89c51 .hex

[Ivalll]

HI, I have problem with programming microcontroler AT89C51. I am trying to make lcd digital watch, alarm and thermometer. I have .C source code downloaded from this site. I converted that .C file to .Hex using KEIL and now I want to program it in chip.I have Universal programmer BEE PROG +. When I select chip and load .hex file in software, I write data without problem. When I read data in chip I see that Software Write that in mdle of chip memory and .hex characters are changed. When I compare it with hex workshop I see that there are a lot changes and my project don`t work. My pcb is ok 100% onlay what I have is backlight on my 16X2 lcd screen.

Can someone tell me what is wrong in programming and is it normal?

Best regards

some dump software cannot execute the hexfile properly so better you try this code with any other dump software

Hi,

My software for programming can load all types of . hex format and . bin but .asm and .c can not. I downloaded schematics and .c source code from this site. Title is lcd digital alarm, clock, and thermometer. Using 89c51 micro controler.

Can you generate for me . hex file? I also see on ciruit diagram is crystal oscilator connected without capatitors. Is that problem?

I tryed to compile . hex file with keil and it don` work.
Please help,
