How do you program a AT89c51. A way to load the code. An easier programming language u can program using C. Your project can be a mixture. Download microcontroller 8051 projects, ebooks, tutorials and code examples. 8051 projects, AVR codes. I need a software to load HEX code to AT89C51.

Best Answer: The Atmel AT89C51 datasheet (2nd link below) talks about the programming method. Tia Portal V13 Sp1 Update 44. The first link below provides a schematic and software.

However, it requires you to. Have another processor and a way to load the code into that one. So it's a chicken and egg problem of sorts.

They do suggest getting an SPI programmable device as the 2nd one and programming that one more easily. Since I have lots of tools for other micros floating about, I'd use one of them and wire up my own thing and write my own code if I wanted to do this myself without buying something. Do take note that both +5V and +12V are required. Also take note that Atmel doesn't recommend that part for anything new, either. Which gets back to the main suggestion about buying a board.

But that also says 'why bother, since the chip isn't recommended anymore and may disappear -- it would be a waste of money to buy a programmer for it.' So, that gets back to why you don't just throw away the chip entirely and get a newer Atmel unit that is supported or else, if you are stuck on 8051 cores, something from Cygnal -- no, that's SiLabs now. The 3rd link provides almost all you need to do it from a PC. It is from Atmel's site. It's another option for you. • Tell us some more • Upload in Progress • Upload failed.

Even though a variety of advanced microcontrollers are available in the market, the 8051 microcontroller still is a good one and finds huge applications in simple electronic products. The wherein 4 I/O ports can be configured to use either as the input and outputs. Depending on the application, it is implemented – the program code is written in it to produce an appropriate function. Burn a Program in the Microcontroller is the process of transferring a program code to the microcontroller’s memory from a compiler software. Generally, this microcontroller program is written in assembly. And this code is converted into hex file using Kiel IDE software, which is then transferred to the microcontroller memory using burner hardware along with a dedicated software.

Once the code is stored in the microcontroller, its function remains in accordance with the program. The main intention of this infographic is to give an example based procedure of Burn a Program in the Microcontroller in an effective way. Thus, the given 10 steps are helpful for those who are trying to build their own simple in an easy and approachable way.
