Ethernet for spec
ZXNet echo conference «hardware.zx»
Hello, CHRV
Not a bad start!!!
I read the datasheet sideways.
1. There is no MAC address, on the one hand it’s cool, you can take any one you like, but with
On the other hand, where can I get it? Mona, of course, will pull from old ISA cards,
throw it away anyway...
2. Supports only one IP stack. In most applications more than
enough.
3. Only supports 4 ports at the same time. Maybe not enough for normal
work. Although you can try listening to different ports at different times,
switch programmatically, or put next to another processor whose functions
there will be support for expanding IP stacks and ports. Here you need to look at the timings
more carefully.
Overall the impression is positive...

Sorry, but I don’t understand what the driver is for ;). That we already have software working with
Internet :D .
This is not about writing a driver, but about writing software. For example, a mailer
HTML viewer, FTP, telnet, ICQ...
Hello, do_se
do_> By the way, I looked at the price, it’s a bit expensive for peripherals, if
do_> take into account that you need a physical layer chip...
If you looked at Kamil’s link, then this is the price of the module, not the chip.
The module is already “all inclusive”, just connect it to the spec. ;)
Hello, do_se
do_> Look here http://www.efo.ru/doc/Wiznet/Wiznet.pl?463
do_> Judging even by this page, there is no physical layer in 3150.
Of course, there is no reason why it should be included in the chip when there are a lot of cheap NICs out there.

Kamil, sorry I missed it!
But that’s not all, there are chips from ConnectOne, they are also based on a similar principle
done.
But the main thing, of course, is the software.
Hello,GriV
In my spare time I studied all sorts of Ethernet solutions for microcontrollers. Came across
interesting feature, chip from WizNet W3150A. The most interesting thing is that Efo offers them in
Russia http://www.efo.ru/doc/Wiznet/.
In short, this is a chip that implements the TCP/IP stack and some of the hardware
high-level protocols.
And it also requires a small number of ports for exchange (i.e., work is carried out according to
similar principle as with AY).
In short, food for thought!

Roman,
In my opinion, this piece of hardware is “The Best” for starting work on implementing TCP/IP
on Speck.

my dearly respected Yuri and Max will be a reason to begin work on writing the upper
levels. Since the interface for working with the 3150 is quite simple, you will probably have
they will not have any problems with the code.
And another piece of hardware can go into the “series”; a driver for it will be enough
mess up.

Also look at page 3 of the datasheet, Features section

Where is this from? On the website of Zilog itself, there is nothing like this in the DS eZ80.
Hello Eltaron
$40, by the way, is a good price for a ready-made device... In the "Programming" section I
I wrote about MOXA NPort4511, so its price is ~$200. It actually
all-wheel drive computer on i80186. On one side there is a COM port, on the other
100base-tx. There is another way - PCMCIA LAN CARD...
Hardware IP stacks are made by Wiznet, but they cost ~$30.
But there is no software support yet, it’s practically impossible to think about hardware
meaningless... And vice versa, as long as there is no hardware, there is no software :)
A vicious circle... First, IMHO, you need to try to implement SLIP before
PiSishki via com port, and the com port is on Kamil’s device. This is the direction
and you need to rack your brains.
PS: When will I reanimate my KAI... otherwise my hands are itching :)

Hmm, I found the same information from Zilog, only in the section regarding the eZ80Lxx.

Hello icebear
I was here at the exhibition "radio electronics and instrument making". there were controllers
with built-in Ethernet and USB.
As for telnet-like programs (SMTP, POP3, FTP clients) - I would
I sketched it out (in fact, this is an institute coursework, I made an FTP server and a TFTP client).
A simple HTML viewer already exists in nature, swapping and inserting pages to
attaching it to it is the tenth thing.
But... The analogue of sockets still needs to be rolled out at the beginning. If Orion had done it in time
RS-232 on spec, then on SS05 FTP it would be already...
