Just upgraded to the 1.58 FW and this problem still persists...

Any plans to fix?

Thx.

Bill:

Interesting device. I'll keep it in mind.

I can probably program the SBL2e, but I can't afford to buy the Dev. Kit just to find out how. It appears that some C functions exist to read the A/D's - those are what I need. But I guess you can't get that info unless you fork over $299.

Looks ...

I bought a SBL2e with the intent of using the 4 A/D inputs to remotely monitor important solar electric system values (voltage, current, temp.) on remote systems that have Internet connectivity.

I've had the device now for a couple weeks, been putting it through its paces.

Hardware-wise, I think ...

There's gotta be a way to get the A/D values out and into a web page.

Help an old hardware guy out here.

I am not looking to buy 1000's of SBL's for a mass produced product. I am one of several who live in an off-grid situation and want to "check in" with our solar electric systems when we are not ...

Hokay, went to Freescale site and downloaded the 52235 manual. Read up on the ADC in chap. 28 and things are much clearer now.

The good stuff is on pg. 28-26. Those formulas summarized nicely what you all were trying to tell me.

I see a lot of "jitter" in the results - they rarely come back the ...

rnixon, Rangeglider:

I am getting the values via a Telnet session.

Here's what I am doing as a real-world test of the A/D's:

Using a LM335Z temp sensor (10 mV / deg. K), taking the output of that, dividing it in half so as to not exceed the 3.3 VDC max input of the device.

The output of the 335 ...

Had some time to experiment with the 2e's A/D's today.

the manual says:

"the value read is a number from 0 - 4095 representing the number of counts"

when using a Pxx? command when the pin is an A/D input.

I am not seeing that. What I'm getting is a 5 digit number that is very, very close to ...

Thanks for the prompt response.

One of the uses we're interested in using the SBL for is to remotely power-cycle a locked-up WISP radio in a cluster configuration such that we don't have to roll a truck. If even one of the radios still has connectivity, we can TELNET in and toggle one of the SBL's ...

Been tinkering with the GPIO lines of the SBL. Turned the "High Current Drive" option ON and am running LED's via some resistors for testing.

After setting 3 - 4 and 12 - 15 OFF (with the Web interface, a Pxx=0, or using a Machine Command), then making that the default with Machine Command MP, line ...

Not even the eval. kit, just the bare device - SBL2e-100IR. I don't need the breakout board, I can make my own cables, etc.

On closer inspection, the SBL2e User's Manual has all the pin assignment stuff on pgs. 14 - 18. It wasn't clear until I looked at the datasheet again that the "pins" they ...
