|
|
Having "pin selectable" software UARTs and interrupts makes the ZX-24 the perfect choice for the "host/device" processor for NetMedia's SitePlayer. I use the SitePlayer along with the ZX-24 for my home automation Web Server. Further details of the Siteplayer can be obtained at siteplayer.com. There is NOT a more inexpensive solution you can find to beat this ZX-24/SitePlayer combination.

I take it that the PCB is your design? Looks neat. Going to sell it?
---------
Unrelated, but since www.netmedia.com now redirects you to their sales page for their new product... NetMedia's going to have problems selling their SitePlayer Telnet end-item at $80 given the Lantronix XPort and other similar products are $50 (@1).

My neighbor and I made it for our home automation systems. The schematics I have released e.g. "Super Com Z" and the "Z Webserve" are for the ZBasic user community for FREE. If there is a "great demand" for these printed circuit board designs, I just could release "FOR FREE" the ExpressPCB schematics and Printed Circuit Board designs. Then all a ZBasic user could do is get two other users together to split the ACTUAL cost of ~ $20 per print circuit card. ($51 + shipping = $59 / 3 - min order of 3 protype cards).
How does that sound for the ZBasic user community?

I have to disagree rather strongly. The Lantronix XPort is $50 at Mouser. It includes the RJ45 jack and magnetics in one easy to handle module. It's based on the 86186 processor and is about a million times more powerful than the braindead SitePlayer.
You can see the XPort mounted on a similar sized board (2.5"x3.8") in the ZX-24 Development Board and ZX-40 Development Board threads in the respective forums.

Microchip's ENC28J60 is now available. While it will need a few additional components, it's low cost ($4.81 in quantities of 25 at Digikey) will likely make it the way to go for Ethernet-enabling MCUs like the ZX family. It's only 10Base-T but what do you want for under $5?

Back when SitePlayer was introduced I asked Jack Schoof about email capability and he said there were no plans to give SitePlayer those skills. I never paid much attention to it after that.
However, I have just stumbled across this thread which shows how to send email using AT commands.

I am using only the low cost "plain Jane" Siteplayer version in my ZBasic microcontroller design. The other model which is the Telenet model and costs 3 times as much. (They both contain Siteplayers but there is a different firmware load on the 8051 chips.) I think your reference is to this more expensive $99 Telenet model.(This will also not do authentication!)
Be forewarned ... most ISP's now days are requiring authentication (to prevent spam). Netburner's products e.g. Parallax Pink CANNOT do authentication along with Lantronic's Xport. I am totally amused when I talk to applications engineers and directly ask them this authentication question. So far only ConnectOne has authentication on their I-Connector email device.
(Authentication is a scheme in which shows the email service provider that you are who you are and not some hack/dweeb wanting to send out a million spam emails on a rouge embedded device)
If you know of any other "low cost" standalone (no PC) email widgets that can do authentication let me know.

on email and client authentication for using the SMTP service
I have used Lantronix WiPort and Moxa NPort wireless LAN to serial devices. These can send emails based on I/O events, power-on, etc. As below, I don't need to give these devices my password (but they can be configured with such).
I've found that there is no restricted SMTP server access (no password) for clients that are inside the ISP's firewall. That is, all cable modem customers in company X's system are inside their firewalls and so is their SMTP server. So they don't require authentication from the clients. They do, now a days, limit the volume of outgoing mail (anti-spam).
I'm not sure how this works for DSL. And, here, Time Warner Cable is required by the SEC to offer RoadRunner + AOL + Earthlink as options. I stayed withi RR. I would think that the other two have inside-the-firewall links from their SMTP servers.
For an Internet based service like Yahoo or AOL or xxx, they would of course need to authenticate the client's SMTP session.

You'd need a lean and mean (and free) IP stack for this chip. Maybe Microchip has one that actually works well. And TCP. And UDP. etc. Many M2M applications need only UDP. But SMTP and others want TCP and that can be a lot of code.
I thought I'd seen some new $5-10 chips with IP on the chip too, not just a MAC/PHY chip.

| I have DSL with the largest phone provider east of the Mississippi - SBC/ATT. They are putting the "clamp of death" on the spammers and they do require authentication. The support engineer at Parallax concerning their product web server PINK said to me "that most ISPs are going to authentication" and that each ISP have a different "non standard" means of implementing this security on SMTP. That's why they can't do email without the help of a running PC to send email. (By having a running PC defeats the purpose of having a completely standalone embedded email device)

AT&T is a totally ruined (by Wall Street) national asset.
SBC is now guilty by marriage.

You must be on the wrong web site because at the top of this page it says
"Zbasic forum - A place to discuss ZBasic and ZX series microcontrollers"

Sorry, becuase of the complete screwing I received from THAT company despite decades of customership, I just go off whenever I hear that acronym.
I'd might kick the dog, if I had one.

Microchip has a free ENC28J60 TCP/IP stack with C source. As you said, most apps will not need the full stack. The question is whether it can be adapted to the ZX. BASCOM AVR has a product called Easy TCP/IP which includes their TCP/IP library for the AT90S8515 and a similar WizNet MAC/PHY chip so I suspect it's possible.
However, SitePlayer Telnet OEM module uses the same hardware as SitePlayer Server. It costs $30 plus a $5 PulseJack and can do email. The thread I cited earlier from their forum has a message listing the differences between the two SitePlayer versions. It does require more board space than Lantronix XPort or a Digi Connect ME but appears to be about as Plug'n'Play as they are and doesn't need a separate 3.3V power supply.
As for email authentication, everything I have found on the topic indicates that this takes place between the ISP and the Internet not between users and their ISP. It does not appear to be an issue.
