Microcontroller are connected into PC by hardware called Programmer.

Programmer are burn your hex file into your microcontroller program memory.

What will b cost of d programmer if i do it by myself??? Whats d cost at market??

[Vicky]

There are many type of programmer, some programmer are compatilble for all 8051 microcontroller, and another for only special chip.

 

When you make programmer at home then you have to search about microcontroller programmer on any search engine,

 

it will approx. to Rs. 150.

 

but there is no guarantee that it will work……….

You can flash the hex file serially using a db9 conector with the help of flash magic. Refer the of ISP programming circuitary in the schematic of any development kit using 89c51. It is a simple circuit, not too many components, normally a couple of capacitors and reset switch only!
