hi, AT89C2051 the method of writing code with C programming is it same with the PIC16F84A ? i found very few example C programming in 8051.
is it cannot use C programming in 8051?

 

I do the bulk of my coding in C, compiled with Keil. Atmel site has lots of examples.

 

Get the evaluation copy of the Keil 8051 C compiler at https://www.keil.com/demo/eval/c51.htm. I would prefer to use 89S2051 instead of the 89C2051 coz the you can download the codes via USB.

 

Very Good tutorial On this site using the AVR Studio4 , WinAvr full instructions here on programming Atmel devices inclusive making up your own ISP programming leads

Hope this helps you

 

verification process used in AT89C2051??

 

Can you elaborate on which of several verification processes you might be talking about? If you are talking about code in the flash memory the software just reads back the bytes it wrote and compares them to the output file from the compiler

 

which other IC can i used instead of AT89C2051???

 

I like Silicon Labs (www.silabs.com) 8051-based processor. Easy to use.

 

AT89C4051 has more memory. You can use this free C Compiler to program either 2051 or 4051:

They have many examples.

 

can i use 8051 instead AT89C2051? if no den plz do tel me wats the major differernce between them??

 

The AT89C2051 is an enhanced 8051, and is quite easy to use.

 

AT89C2051 belongs to 8051 family.. read more details about 8051 here.
