hi.
I have just started to work with 8051 microcontroller,
and an amusing question entered my brain.
what does a programmer do in order to send our programs to a microcontroller?
looking forward to your help and ideas:

Re: 8051

You should find a basic MCS-51 book first.

There are many free E-book about 8051 in E-Book upload/download forum.

Re: 8051

Hi,

As I understand your question, you want to know how to put your code into a 8051.

There are some different kind of chip programming. You can find chip that need a programmer tool or you can find chip with ISP (In-System Programmable) functionality.

The later kind is the more flexible one. Once your chip is soldred on your PCB, you dont need extra material to reprogram it. Only a serial link is needed. The chip an amount of flash memory to store your application.

With the first kind of programing technic, you can burn your chip on a programmer, with a bootloader application. This enables you, when your chip is soldered on a PCB, to download and launch your final application as many time as you will without the need of an external programming tool. You only need a serial link to download your app. If you chip include flash memory, it is very easy. If not, you need to have an amount of RAM which can store your application.

Hope that helps.

Go to Philips Semiconductor
She has good documents for 8051

After you have ideas about the hardware and instructions, go to find
an assembler and start to write and test some codes.

Change to C compiler if desired

Re: 8051

To send programs to microcontroller u have to burn that program in the microcontroller using a microcontroller programmer.............Many commercial programmers are available for 8051 , 8052 etc.........

for more info www.8052.com is very good resource about 8051 , 8052 etc microcontrolllers...........

As I understand your question.
in a word ,the programmer send the file(.HEX) to the mcu.

Re: 8051

No...you didn't understand at all...


1. It wasn´t a question!!

2. A programmer never sends a HEX file to an MCU!!
