Re: NB is it time to expand out to other platforms ?

The basic message is a lower cost smaller MOD5270.

What features would you be willing to give up?
Smaller is hard as the connectors pretty much set the size limit,
what pins would you vote off the island?

Re: NB is it time to expand out to other platforms ?

When you say low cost what are you really expecting? So how low is low enough? The SBL2E is 19.99 in quantity. Is that low enough? We were thinking about selling bare pre programed chips for about a $5.00 adder for the software? Is that low enough? Eventually hardware will be free (IE sub $1 for 32 ...

Re: NB is it time to expand out to other platforms ?

We are now releasing a dev kit for the SBl2E, it currently does not have a debugging solution, but its a low cost part. Sales is also discussing selling the SBL2E chips as pre programmed parts to customers that are interested. I've ported the core RTOS and some of the loader code from the SBl2E plat...

Re: TCP connections recycle used port numbers

Retranmission and Dup Ack are a normal part of the way TCP operates. I'd be interestied in TCP ports reused, that is different. One way you can see this is if you initiate connections from the netburner on power up, the ports get reused between resets of the board as the system uses the timer to gen...

Re: FPGA Blade for PK70

The problem with a stackable module is that there are processor pins that would be useful to the FPGA that are not brought out on the existing 100 pins. My thought was to add the FPGA to the core board and attach ALL the processor pins to it then bring the 100 pin headers out through the FPGA. That ...

FPGA Blade for PK70

I've just finished a prototype FPGA blade board for the PK70. It has a Xilinx XC3S500E Spartan 3E FPGA on it and a DB-62 pin HD connector (The same size as a DB37) I have simple verilog code running on it that turns it into 48 bits of bit by bit programmable direction GPIO with full register read ba...

Re: TCP_ERR_NONE_AVAIL (-5)

It means the system is out of TCP sockets.
Are you closing the sockets when you are done with them?

Even if you get an error you still need to close the socket.

It is "part" of a solution. //Find out how long ago we heard from the other side of the connection.

Re: SBL2e Board

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 th...

Re: Best way to count pulses...

Why zero the counter?
When you zero you could loose a pulse, the counter is 32 bits, so just remember the last value and calculate the difference.

That way you can't loose any pulses.
