Best ASM to HEX Compiler and USB Programmer Compatible with AT89S51 Microcontroller

Good day engineers,

I have an issue that is bothering me for long. I need an asm to hex compiler of AT89S51 and USB programmer the same IC AT89S51.

I come across some compilers and programmers but the said AT89S51 is not on the list. While it is on some, but the programmer may need a kind of soft code to feed a micro controller in the circuit and the codes are not available.

I'm confidence that my issue will be solved forever in this experts forum.

Thank you all able engineers.

I remain.

Hi Mauzu.,

I found this link on the internet http://www.technoburst.net/2010/09/at89s51-programming.html
It mentions about AT29s51 compiler and program

Hope it helps =)

Going from .asm to .hex tells me you want an assembler, not a compiler. Regardless, it looks like Atmel's Developer Studio is free for the download.

The "Devices" tab says it includes the AT89LP51, but http://www.atmel.com/devices/AT89LP51.aspx says this one is 100% software and timing compatibility with AT89S51 which you're asking about.
