8051 development tools
Started by Stu Cazzo 9 years ago
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
Started by Yukuan 8 years ago
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

Started by Edo Reshef 9 years ago
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

I need to send short RF messages (approx: 2 bytes) between 8051

I am working on an 8051 project. The code size has grown very large. I

Started by Jean Nicolle 8 years ago
Lots of companies have 8051 compatible chips... Atmel, Dallas, Philips,

Is the 8051 CPU public domain, which could explain why so many guys chose
to use it?
Or do these guys still have to pay royalties to Intel?
Thanks.
