> Any one have sample program for this...??
??? Why do you need a sample program for programming your device? Or do 
you mean something like the good old "Hello World" program?

> Is it need to install another s/w..??
No, for device programming the FLIP software (and proper wired hardware) 
should be enough.

> how can i write program (in ´C´ language)..??
As you wrote above, you're using Keil. So what's the problem? There 
should be a example folder.

hallo Ralf,

Thank u for ur answer
n sorry for my questions.

hallo Ralf,

Ya i have all Software n also Keil Example folder.
I know how to use that all softwares and no need of another Software.

when i try the example project in Keil than error is "Target not 
created"
The target is Simulator. I search simulator on net but i will not find 
that.
I don´t know abt other tagets. I just wanna see output of any one 
program.
I already try to run 3 sample programs of Keil.

ya, i want the program like "Hello World". this same program is in Keil 
example folder, but i can´t able to see the printed output like "Hello 
World".

I also try sample programs on Flip and one can see the output in 
Hyperterminal. I try but i will not able to see the output.

I am trying to do ISP(In System Programming) with RS232 in AT89C51CC03.
I have to make one program in which i give Analog Signal with Pot (in 
AT89C51CC03) as input and take PWM signal as output.

I read almost all datasheet for this softwares and for AT89C51CC03.

I connect AT89C51CC03 controller to PC and i saw that the data send or 
receive through RS232, while the RX(Red) and TX(Green) blinking when i 
run program in FLIP, but i can´t see the output.

I know 'C' Programming, but i am new in Embedded system.

If u have any sample program related to my project requirment then reply 
me.

If u have any advice then also reply me.
