AVR-Chat

Hi there,

Is there any reference guide to translate 8051 asm code to AVR asm 
code? or let me know usefule infomation.

Best regards,
Kevin Shin

The architectures and instruction sets are quite a bit different.  I 
suspect that you're going to have to first understand what the 8051 
code is doing and then implement the same logic in AVR code.

8051 is enough different from AVR that a 1:1 translation
makes little sense. For example, an 8051 MOV immediate
becomes an LDI in AVR.

I used SPASM, an 8051-like assembler for PIC's, but when I looked at the 
code generated and the redundancy in some cases, I stuck with Microchip 
MPASM assembler to write programs. Mine always came out quite a bit 
shorter.

I haven't tried any program that uses 8051-like assembler for the AVR's as 
I've just gotten started with the AVR's. There may be something out there 
that will convert 8051-like code to AVR code.  

I've figured if you're going to use assembler, you might as well use the 
language the manufacturer recommends for the device.

8051 is a CISC Processor and AVR is a RISC processor.
