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

8051 serial problems
Edo Reshef - 2004-04-21 11:33:00
Hi,
I have an 8051 controller that communicates over RS485 to other 8051
controller. The communication is half-duplex at baud of 57600, and it
works great. So far so good.
Lately, I'm trying to make the 8051 device talk with a PC, since it is
57600 and I have RS232 RS485 converter this shoul...8051 development tools

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
