8051 development tools
Stu Cazzo - 2004-06-14 23:13:00
Hello,
I want to get started on an 8051 project. I already
know C. What I am looking for is an 8051 eval board
that comes with a C compiler, flash burner, code
debugger, etc...
In other words, I want to develop some basic, generic
8051 code in C, compile, link, download it into eval
board and...
AVR or 8051
Yukuan - 2005-01-19 11:01:00
If anyone can tell me when to use AVR and when to 8051.
We all have known that AVR has fine instruction set and
is much faster than 8051.
During product developing, what make you choose 8051?
Any comment is appreciated.
Thanks

Edo Reshef - 2004-04-21 11:33:00
Hi,
I have an 8051 controller that communicates over RS485 to other 8051

works great. So far so good.
Lately, I'm trying to make the 8051 device talk with a PC, since it is

Hi, I have yet to see a project written in C where the 8051 was the best choice
on either performance or price. C is to the 8051 what windows is to a pentium.
Of course is your poduct doesn't need much performance then allmost anything

Or do these guys still have to pay royalties to Intel?
