Re: beginner and 8051

actually, I was thinking about at89s. the only reason I asked about
silab is their development board with jtag for about 70$.
but, how usefull jtag is? can I get the same result with software
simulator?

Hi All,
I'm a beginner and I'd like to start from 8051 . as I can see-the only
cheap boards with jtag are from silabs, right? there are a few of them
for about 70$ , which one should I buy?
will I be able easily move my code to other 8051 mcu like ats89s?

thanks.


an alternative is start with an at89s52 or similar atmel parts is
available a almost-0 component programmer ( trough the PC parallel port
) so you can start with a home built proptotype board.

there are lot of hardware/software project on 8051 available on the net.

with an at98s5x an old static ram an a 74hc373 o 74hc573 a 74hc00 and a
max232 you can build a system that is able to receive code trough the
serial port write in the ram and execute from there.

BTW the controller must be preprogrammed with one of the monitor
available on the net

.
