Cheap logic analyzer SPI i2c UART 

You forgot a couple of words in that description, "....incredibly stupidly priced ripoff Saleae device"

As the guy said "its a product from China, so its OK" ! Crikey, that's some faith, I work more on the basis "its a product from China, so will it electrocute me".

@@poruatokin A completely reasonable price for an excellent product, which saves lots of time as it is so easy to use! You pay for the software which is a dream :)

@@louisdavies5367 I use sigrok, which is open source, does the same thing with 10$ clones (or anything else, they support anything you can think of) I didn't had any problems with it yet. If you have time give it a go.

@@umutnumanoglu1056 I have tried a cheap one with pulseview which is actually quite good!

I am going to state the obvious. *Click on OTL's channel logo above* go to uploads, and watch *"001 Sigrok and Logic Analysers"* You probably need to go get a snack and get comfortable first. The video is over 1 hour long. It's detailed, goes through all kinds of cheap hardware options you don't know about, how they work, how to use the software, the nitty gritty details about interfacing and hardware limitations. The dude knows his stuff but is practical, down to Earth, and is good at explaining things. I guarantee, because your here, we have a common interest, and OpenTechLab is the kind of channel you seriously want to know about. I have no affiliation, and have never met the guy. The aforementioned video is not monotized. I'm just a simple hobbyist with a nonmonotized channel making a simple suggestion as a viewer like yourself. No one is trying to make $0.002 AdSense by telling you this. The Google AI had to suggest the OTL video at the end of the next one I watched after this one.. because I wasn't smart enough to connect this comment was a gentleman's hint. Well...this message is the rude American version telling you the obvious... *Go watch OpenTechLab now*

Sigrok and Pulseview are open source and I find it easier to view as it is white background as opposed to black. Great little analizers!

I'm a sub of OTL with all due respect you use clones on your channel too. The only difference is that you use open source software. You are still using cloned pirated hardware anyways. Wouldn't you agree?

Constructive Bytes, The "pirated" hardware as you say is pretty much a datasheet implementation of cypress chip. It is open to anyone. The whole value is in the software so if you want to keep your pirate tendencies at bay, using open source is enough.

as soon as they forget to brick third party hardware. dickheads.

Saleae actually is based in San Francisco, California. The product in this video is indeed from China but it is a cheap knockoff using their name without authorisation.

This software doesn't have K line bus. I never used that kind of bus comunication. I don't know what to recommend.

Yes all electronic devices must have the same ground in order to make a comunication. GND pin is the "0" volt rail, is the reference voltage for a device. That means arduino 5 volt level is 5 volts respect to his ground pin (Arduino GND) and the same for the logic analyser. If you don't connect arduino GND pin and Logic analyser GND pin together, arduino 5 volt level might be 2,5 volt level to the logic analyser (or other voltage) because the voltage level for every device is relative to his ground pin. If you conect arduino and logic analyser GND pins together they have the same reference so 5 volt level of arduino equals to 5 volt level of logic analyser. I hope you understand the explanation when I was a beginer few years ago I didn't understand the concept of ground now after 12 years I fully understand. If you have any question i will answer to you :). PS: I'm from Spain so i'm sorry if i did any orthographic mistakes, I hope you fully understand the concept and why you have to connect GND pins together. PPS: As a bonus! Some devices have one or more ground pins for analog circuitry and other ground pin for digital circuitry (They are separated). Sometimes you want to measure an analog signal and you need another voltage reference diferent from the digital voltage reference. But this is more advanced stuff... :P

Hi, Which of the links doesn't work? I've double checked each one and they all work. Keep up and thank you!¡!

it was the youtube sub download links but i checked them now and they work well. thanks man. also what is the use of such tool? also can u do ethernet shield well detailed tutorial and how to connect our projects to the world wide web?

this will only work as digital debugger

No, it is just test example.

@@guest7329thanks for the reply. even if I connect the analyser, software is in simulator mode and in the title bar it shows disconnected. Logic analyser is not being detected by salae software.

@@vijaynagaraju9701 which os you use?

@@guest7329 I am using Windows 8

@@vijaynagaraju9701do you connect analizer directly or via USB hub?

Have you found the issue?

well... because it's cheaper. ok?

...and because the original creators do not seem to understand basic retail business. They are still trying to sell this product at 30 times the price of the clones. They should have acknowledged their mistakes, and created a competitively priced option that is no more than double the price. They could have used the marketing momentum/exposure to create something new that they could build a business on. Instead they tried to appeal to emotions and did nothing to salvage the market. The moment the clones appeared the damage was done. Their investment was compromised. The only positive response was to cut the losses and try to use them as an advantage. Appealing to the consumer's emotions, trying to stop/disable the clones, and or whining about the problem is the response that will keep them marginalized or put them out of business. The failure to protect their product is on them. Blaming the consumer or the cloners is a guaranteed path to nowhere. Don't get me wrong, it sucks. I feel for them, but there is no room for emotions in running a business.

Quote from www.saleae.com/about "It's more fun to be a pirate than to join the navy.”

@@UpcycleElectronics well, the original creators made their analyzer for professionals. A professional engineer who's monthly wage is 4000 USD can easily make the company purchase a tool that costs "only" 500-1000 USD if it's needed for the job. However, the average Joe home user of course will not be able to buy it. Microsoft solved this with "home edition" and "pro edition" of windows, but you cannot do that with a logic analyzer, because it needs to function the same way (mostly). Well, at least the chinese have now solved this.

because of historical imperialist interventions in 3rd world countries makes it so it's these "official" (and overpriced) products are prohibitively expensive to buy. so we go with the cheap "copies" that work. USA stole our democracy and resources, so now "piracy goes brrrrr" ;)

What was the problem because i am planning to buy one

You should be able to if you pick one leg of the differential pair and ground. The decoding is the same as rs232, with the uart decoder selection.
