Your video helped me a lot on setting up a Hantek 6022BL Logic Analyzer with PulseView software from Sigrok project. Thank you.

Great video. I know this was 4 years ago but I have a $650 4 channel oscilloscope that, for what I do with it, is no better then this. I ordered one. Also, they have fixed the Android app I guess, it runs on my phone. Must wait for Banggood to test it. Thank you.

It''s funny, I was thinking about buying a logic analyser yesterday but didn't know what one to get. Then you go and release this video! So I've bought this one as it looks like it'll be great for my purposes. Cheers!

After nearly a decade this is still the best to explain … timing … freq change (mine at least 250k for Apple m2 with stm ) … 1g sample … pull resistor ground -sda … usb host android … so much info. New version of i2c still confused me as there are three now. And the device is now thumb size!

The small pulse at the start of the serial transmission is the time it needs to put the message in the transmit buffer of the arduino serial driver. . .

When I looked into Sigrok, I thought I read that it needed to replace the firmware on the analyzer and that had turned me off - assuming it would have disabled the original crippled/cloned functionality. Thanks for this!

The firmware is loaded into device RAM at runtime. No permanent changes are made.

By now, PulseView seems to support analog channels.... Is it possible to see the live / streaming data of the digital and analog lines?
@ianknight4013
@ianknight4013 3 года назад
Big thanks for the video i'll be getting an analyzer ASAP as going to be really useful for debugging the serial protocols. BTW I guess one of the other posts picked this up but the little i2c device you had looks like a tri axial accelerometer and not a magnetometer (compass)
@iforce2d
@iforce2d 3 года назад
If you mean the GY-273 it has a HMC5883L compass on it.
@ianknight4013
@ianknight4013 3 года назад
@@iforce2d yes your right is a compass, when you held it up i just saw the x,y,z and as i have been upto eye in accelerometers for couple of years i clicked into accelerometers mode... I'll be ordering a GY-273 soon.. BTW have you done much testing with the GY-273, just wondering what it reports, North?
@iforce2d
@iforce2d 3 года назад
lol not that simple I'm afraid. There are 3 sensors, one for each axis, which measure the strength of magnetic field. The strength will be highest when aligned with the magnetic field of earth, and lowest (a negative number) when opposite to the magnetic field of earth. By looking at the minimum and maximum values reported by each axis, you can figure out how the sensor is oriented relative to magnetic north. Then you have to use the magnetic declination of your location to get geographic north. This video covers some of these points: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lEY-gmt6ijg.html If you're using arduino there are some libraries around that will help.

Nice Video. For I2C to work both clock and data lines need to be tied to VCC. When a device on the I2C bus wants to communicate it pulls the lines low, this is the way they "talk". So if you don't pull the data line (SDA) and Clock (SCL) High, they can't communicate. That's why you needed the pull-up resistor. Tried the Android version today, unfortunately its still not working :-(

The serial is asynchronous, I noticed that too :p I'm not sure if it's hardware or software-based, but obviously Serial.print only puts the data in a buffer. It's sent later, in a serial interrupt probably.
@byronwatkins2565
@byronwatkins2565 5 лет назад
Arduino buffers the Serial messages and utilizes the UART's interrupts to sequence the transport byte by byte.

Hi iforce2d. I have a LHT00SU1 but can't get Sigrok pulseview to connect to the device. The USBee AX does work on the device. Do you know what to do to make it connect? Different driver?

This is called "hardware buffering" ! That's why the output goes down quite rapidly and not at the end of the transmission.

I can't find information about sampling frequency for digital (logic) inputs. What is maximum sampling frequency for logic inputs? 24 MHz?
@iforce2d
@iforce2d 7 лет назад
According to the product page, it says 16MHz. Using this Pulseview software on Linux though, 4MHz is the most I can get it to do. Anything higher than that and it stops responding and I need to unplug it and plug in again.

@JamesSleeman
@JamesSleeman 8 лет назад
At 23:40 (and subsequent) you say you had a resistor between GND and SDA (pulldown), I think you mean between Vcc (or it looks like 3v3 in your case actually) and SDA (pullup), which is what I would have expected. Otherwise, great video I didn't know that Sigrok and Pulseview had gotten so good, I have been resisting buying one of those cheap analyzers because I didn't like the idea of ripping of Salae's software, with Pulseview working so well that makes it nicely legit.
@iforce2d
@iforce2d 8 лет назад
+James Sleeman yes, that's what I meant to say, sorry. It's between 3v3 and SDA. I also forgot to mention basically what your second paragraph says too - it's nicer to have everything open source instead of a sneaky side-stepping of something else.

I don't think the USBee AX has analogue inputs which may be why you can't read anything on ACH1 and ACH2.
@paulk9532
@paulk9532 7 лет назад
The product listing on BangGood claims 2 analog channels at -10 - 10v. This matches the specs of the legit USBee AX (www.ee101.com/axmanual.pdf). USBee went out of business and was acquired, so all that's available now are clones.
@martinlorenrd4073

The ARMFLY AX-Pro has it (1 ADC, and a pin to select between channel 1 and 2). See my video above...

Is your particular clone hardware compatible with the "new" Saleae software - it seems to be fully cross platform: support.saleae.com/hc/en-us/articles/201589175. Though it still seems to be missing the ability to trigger on decoded values, which is a bit of a shame (their workaround suggests grabbing a pile of data and using excel to search... /sigh).

Have you tried to use it with Salea? This device seems to be a clone of USBee (or some similar brand), but reportedly could also work with Salea, you only need to reprogram the eeprom. The reason I'm asking because I'm using salea with a dummer device and the software is pretty awesome (in terms of features, reliability and performance), far by the best among the softwares you can find on the internet. how to modify it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nLgGfRGcNSk.html www.jwandrews.co.uk/2011/12/saleae-logic-analyser-clone-teardown-and-reprogramming/ (at the bottom "Cloning Other Devices")
@iforce2d
@iforce2d 7 лет назад
Yes I tried Saleae but iirc it was Windows only, which for me takes it out of consideration for any application where a good alternative exists on Linux.
@nyeleskettes
@nyeleskettes 7 лет назад
Thanks. I meant if you tried this specific device with the salea interface (afaik they ship it as a usbee clone that has a different id, just like described in the urls above).
@iforce2d

Yes, I used it with this device. iirc I had to open it and move a jumper inside.
