Open Bench Logic Sniffer / Re: New Logic sniffer is broken???
alright so here's my test setup:


I was getting readings like this:


I did the firmware upgrade here: http://gadgetfactory.net/logicsniffer/i ... r.Download

Now I'm getting readings like this:


And now I am very happy!  Thank you.


will a mod make those links valid please?  Someone might benefeit from this.  I had to remove the img tags, remove http from the front and put a space between com and net so the board did not see it as a URL.

Open Bench Logic Sniffer / Re: New Logic sniffer is broken???
In order to get a package which I think will do the job, it required 15 tabs in firefox, 4 downloads and a windows virtual machine....  I can't seem to find the "logic_sniffer_3.070-Demon-Core.bit"...  The page I found had 3.06 in untested status, and I've got 3.02 of some flashing utility.

Can someone zip up a package with a date, or revision or something?  I don't have a problem with using Windows, but I've now got to reboot my system, refire up my virtual machine, and then attempt to flash, and I don't even know if I've actually got newer firmware then what's on my logic sniffer...

[quote author="ian"]Hi adamoulter,

Thanks for the report, I'm sorry about the problems with the OLS. It is certainly possible the hardware is damaged, it should work fine in all configurations, including 8channels.

Please return your Logic Sniffer for a refund. It is an open source project we all work on, we'd never want someone to be unhappy with it. I'm so sorry for your frustrations.

I am happy to admit that everything we work on here is a POS and not a commercial quality design, however Seeed's (or Gadget Factory, if from there) quality control is top notch. Each OLS receives a complete self-test at the factory before it ships. The test connects the 16 unbuffered channels to the 16 buffered channels, and a test pattern is generated internally by the Logic Sniffer. Something can always happen during shipping, though it is very rare.

As for the firmware quality control - we're just a bunch of amateurs having fun. There is no quality control on the firmware at all. The closest we come is a release candidate, but usually we just wait for bug reports to roll in. We try to make sure everyone is aware of how the project works, and why the hardware is so cheap, and we don't want you to be stuck with the hardware if you didn't know what you were getting.[/quote]

I see what you did there...  Please don't play the rally open source card on this issue.

I noticed some dull pins on the XLINK chip.  I reflowed the solder on the XILINK chip and now it seems to work in non-RLE mode at all frequencies.

RLE is still giving VERY erratic readings.

Bus Pirate Support / Re: UART non-standard bitrate?
Thanks.  I don't think I understand how to use that tool.. My processor runs at like 1ghz and the baud rate is 9700bps.    Also, i run Linux.  Is there a java program I can play around with?  Java is awesome because it's cross-platform.

I had no unused pins.  I will upgrade the software and try again in the morning.

It seems rediculous that a 32 channel logic analyzer would be glitchy on just 8 channels and require a firmware upgrade to operate properly out-of-box.


So....  I will spend another couple of hours on it tomorrow.... for what reason???  Because some guy on the forums said his was running a speciffic version of firmware and he could use one line properly....


Does yours work properly with 8 channels?  My Arduino is set up to sequentially turn a group of pins on, then back off..  if this thing can't read that, then its either a POS with lack of quality control on the firmware or there was lack of quality control at seeedstudios.

Open Bench Logic Sniffer / Re: New Logic sniffer is broken???
What?  I can't just leave it at 200mhz and expect it to not give me a glitchy signal?   

Im sampling something less then 16 mhz.  Id expect it to be around 4 mhz.    100 should sample it just fine right?  IIve tried all different rates.  Nothing is working with a clean sig.al. 

The problem is noise...  200mhz looks about right, but glitches.  100mhz shows me static.  It would appear to be broken with a bad ground on the chip somewhere....  look at the 200 mhz signal...  it should not be dropping out on all channels at the same time should it?

Bus Pirate Support / UART non-standard bitrate?
I am trying to communicate with the SIM card port on my phone.  Apparently it uses 9700bps.  I would like to try to talk to it.  How would i specify this non-standard bit-rate?

Dangit.... 

I am an electronics technician..  I've been working with this unit for about 16 hour straight now and it's acting like channel0 ground is broken and it is giving eratic readings from channel 1.

Open Bench Logic Sniffer / New Logic sniffer is broken???
Hello, I am receiving eratic readings from my logic sniffer.

I hooked up my logic sniffer to my Arduino Mega.  Then I set it up to read the pins.  The unit showed very unexpected results.
