Listing Program At89s51
Hi all,I am a member of these forums for quite a while and generally don't have too many hardware issues.However micro-controllers are all very new to me. I have just about managed to master the Arduino Uno and now need to go a step further.I found a very nice project online that I would like to build.The original controller was an AT89C51 but I understand that the AT89S51 is compatible and programming is even easier.The project designer posted his source code and his description is' The program is written in embedded C language and compiled through KEIL (IDE) cross compiler.' I downloaded the evaluation version of Keil uVision5 hoping it would be of use to me, but unfortunately it has a 2Kb limit, the full version is $2,600 and I don't see myself paying as much as that for a hobby project.What I would like to know is:1) Are there any alternatives to compiling the source code in an alternative compiler, what modifications would I have to make to the source code.2) What is the easiest way of programming the AT89S51 once I have compiled my file.I have attached the source code in a text file in case anyone cares to take a look.Thank You. Daisy model 25 serial numbers. After several hours reading, - always a good place to start, I eventually managed to compile the source code. And now have a very nice hex file.
The next step is to find a way of getting it on to my chip.The biggest thing I have learnt, is you don't learn C (or assembly either ) in an afternoon!I am not far short of 60 and between, automotive electronics CAN LIN etc., new emissions regulations, and Spanish, I am now studying harder than the average full-time student, and running a very busy workshop as well for 50 + hours a week.I see that some people have managed to flash the 89S51 with an Arduino and I am willing to give it a go. Any suggestions or comments on this route are welcome. I really appreciate that people here are prepared to help and share their experiences.

For FREE compiler, I think, most people end up using GCC. I have not setup it myself, but I probably will later.Using Arduino board is probably by far the easiest. You can get copy/clone of Arduino Uno for 8 USD.An interesting option with these 8051 chips is using one that has bootloader on the chip. That way you don't need a big/dedicated programmer circuit. That is what I am planning, I got Microchip's SST89E516RD chip, the circuit that I am going to use have RS232 chip between the pc serial port and the SST89E516RD. Also, recently, while discussing a Maxim 8051 chip I learned that they have one that comes with bootloader too.

I compiled your code to less than 1.5KB so the free version will work.There are numerous programmers for 8051, typically vendor specific.The ones I have used a lot is usbasp, and they go for less $5 on ebay and also work on AVRs too. You can use a customized avrdude to program it but I used a chinese programmer, progisp, to program it - it supports numerous Atmel 8051s out of the box and is much faster than avrdude / avrdudess. But you have to get a hang of it as it is in Chinese - after a few tries, I go by the icons, like reading a picture book.
