SBL2e Board

[Ridgeglider]

I notice a new module is emerging on store, the SBL2e Board. Could you provide add'l details? I like the small size, low cost and AD ports. The brief description suggests that it's only configurable via an http interface, not programmable.... I'm pressuming the serial data appears on a telnet port, like many of the serial to ethernet examples for the other modules? Is it a one way transfer, or bidirectional?

No chance that instead of simply forwarding, the module could parse a serial stream and put up derived data as a UDP table instead? I figured that you guys must program it to forward the serial stream to ethernet, so I wondered what it would take if a standard and known stream could get parsed first? Sorry, but I had to ask... I know this is basic for the other modules.

The part as programmed does Serial to Ethernet useing TCP or UDP, web configured.
It also does GPIO and A/D over a TCP port.

For any high volume applications we could do custom software builds.

We MAY eventually release a development kit for this hardware.
The device has very little RAM, 32K, and the OS tcp stack and environment use about 14K of that.
The network programming environment is non-standard, its all based on callbacks for various network events.
The development tools are solid and seem to work well, but our first beta trial of this product was a nightmare
as the customer had an extreme case of feature creep cycling through engineers.

I'm personally afraid of what support will look like. I answer multiple support questions a week where someone
allocates a 20K local variable and steps on the 8K stack, whats going to happen when the stack is 512 bytes?

If we do release the development environment it will probably include a hardware debugging component and will
be priced accordingly, $399 $499?

Any thoughts from the group on how to control expectations?

My personal thoughts are:
Require anyone buying a development kit to attend a free 2 hour on-line class.
Provide a very clear set of performance limits that shall not be violated.
Require developers use a limited set of predefined application templates.

Things it presently supports:
RTOS
TCP (4 connections)
UDP,DHCP,ARP,ICMP,HTTP get and post, web-server callback/variables.
IPSETUP, Autoupdate, Taskscan.

Things it may support in the future:
Send Mail.
Limited FTP client.
Limited FTP Server.

Things it will never support:
SSL,SSH,SNMP, File system.

The SBL2e board / Motherboard is fairly slick
It has a future-feature of I2c
Is that for the near future, or farther out?
thanks

The SBL2e was released last week. It's available at the www.netburnerstore.com website. $19.95 in 1000s
