Hi, would you mind sharing details of the hardware and software you used? That's very interesting.

Can you share the driver to make it work with USBee AX? For me it only worked with Pulseview, under USB device (installin WinUSB with Zadig), it never appeared under usb controller

I managed to download USBee AX Pro software from another source, but cant make it find the device. Installed the WinUSB driver, but still it does not recognize. When I tried with sigrok PulseView it worked perfectly though, wonder how you managed to get it working with USBee software

I cant reach the website you mention to download usbee

💌🤟

It looked like you are using esp32, that has an inbuilt CAN controller and only needs a 3.3v transceiver SN65HVD230. More info on my other GitHub repositories. Feel free to message me as I have numerous PCBs for CAN on different MCUs, ranging from attiny1514, atmega328p (nano), esp32

Hello. What kind of batteries they are? Li ion?

10:10 I suspect you got the sporadic errors due to the high bandwidth, and switching to x1 reduced the bw considerably. Almost every modern scope has a 'limit BW' feature which would help as well. Regardless, great video.

Autel Ticket Number: 2794689 (6th Nov 2024) - Subject "TPMS Hot Function Faults" After working with Autel and testing several different scenarios it appears to be something Autel Software Engineers need to fix I emailed them again on the 10th November 2024 to see if they would confirm if a fix would be possible for them to do I will keep you guys updated...

Hi. I'm interested to calculate RPM from the sensor. But should we need "IRAM_ATTR" for interrupt? just found it, IRAM_ATTR is only for ESP family. Thank you sir.

I just reinstalled Oct 2024. I found the following differences which you need to take account of: 1) SDR Sharp is now revision 1920 2) When inside the Plugin-Rtl433 install folder you now have to Unzip 1.5.7.0 to get the 3 files you need 3) Other than that it worked as per this video

Thanks, this kinda cool to see. The other video where you show to download it, is a little different now. The install folder has text document where to download the master, but figured it out finally. Now I just need to find out where my temp sensor is, still transmitting after losing it a few years back.

fabulous vid ! Can this rpm sensor output to iBus sensor port, say iA6B ?

usefull video thank you

I've managed to get all warking as you do. Except the protocol windows poping out. Is this another plugin?

So far you gave the best explanation. Thank you

Really helpful! thank you

Are the decoded CAN/Serial messages able to be saved to internal or external memory? When I logged a CAN bus to CSV on mine, it just seemed to record the raw values 🤔

Hello to you I would like to do the same thing with my sds802x hd oscilloscope if possible. THANKS

Any reason why I have no plugins folder?

This was useful, thanks. I hope you get a few more views.

is it possible to continuously monitor/stream/see live the LHT00SU1's analog and digital signals?

I have been looking at these units, wondering if they would pick up engine pulses from an ignition coil on a motorcycle and give a clean square wave. They are cheap and small. Do you know whats inside them and how they work?

Good Job As always, I didnt want to read the manual Subscribed

You are great, thank you so much for making this video, I was too scared to do this and got lost on the eevblog didnt know how to start. But after seeing your video with great and simple instructions, I will follow this tutorial :) One question, instead of the SD card do you think we can use 64 gb USB?

Thanks a lot, sir. Great and easy fix which helped me. 😊

Many thanks for posting the video, it's been about 9 months since I've used my AP200 to reset my oil and service intervals, but I seem to remember I used the prompt ignition 2 has engine running also for live data . Once again thanks for the video

At 20:55, after you press "Date/Time", you got the "NTP" selection. However, I don't have this "NTP" option, and the screen just have "Date/Time" and "Display off" selection. The middle 2 selections, "NTP" and "Time Zone", are misssing. Do you know how to add them? I am using a SDS1104X-E, with Software Version=6.1.37R10, Uboot-OS Version=8.1, FPGA Version=2021-11-08, Hardware Version=01-05. Thx !

How

Informative video. I know a little more about my analyser than I did 30 minutes ago, but bro, you gotta work on that teeth sucking tick.

Thank you for the experiment. I have the same device. I use it with sigrok. I tried to download the usbee software, but it is not available anymore. Have you tried using a 10x oscilloscope probe to be able to test voltages higher than the 10 volt max this device can handle?

Very useful thx - I'm just starting to play with some CANbus home automation gear.

Is it possible too just make a single esp -32 rolling code module

Cheers, it worked perfect just as you laid it out. my SDS1204X-E is updated for MSO,WIFI, AWG.... 😀 thank you

How can i get a copy to test?

It will be a software emulated ev1527 or a Princeton Technology chip; viewing the waveform will tell you which one. Usually available between a receiver chip and decoder IC on the receiver pcb. Reminds me of my decoding sessions as a young teen, using a receiver (from a junked car alarm), tape recorder, and data slicer into an 8 bit home computer. Really bodgy, but it worked. For ASK now, I'd simply interface a bare receiver to the input of a sound card and record the result in Audacity for analysis. I'd be using a bare 433MHz transmitter module connected to an arduino to generate the signal rather than the sledgehammer esp and cc1101 combination. Soundcard is fine on the demodulated signal from a receiver for these things as the data rate is so low.

This is how i'd try, just from your description (not looked at the code). Capture 1, then send random guess to move along, send captured and repeat. If the random guess is right, door opens otherwise you'll only need to send as many attempts as you have in the numbers list. Trying to roll your own rolling code without knowledge of cryptography is usually a disaster. You should see how complex the original keeloq was, but it still was broken after the method used was leaked.

Thank you so much for this video i bought the V4 myself and its been difficult to find videos for the new version of this dongle

I was playing with this.. (I set a wide bandwidth) of 200,000 to grab a wack of devices.. (BaseBand Noise Blanker) not used.. RF Gain 32.8 (But.. I say This Plugin Needs work also 😊) Fidle Fidle

This didn’t make sense the first time I viewed it. When I realized you were working with an ARM Teensy, I started to understand. You’re not saying anything untrue, but it would be more accurate if you replaced most of the places you say “Arduino” with “Teensy 3”. The original Arduinos and original Teensys were AVR MCUs. AVRs use DDRX, PINX and PORTX registers at a low level for port manipulation. Starting with v3, the Teensys became ARM MCUs. ARMs use a completely different register system to control IO bits in a completely different process than AVRs. When the Teensy 3s came out, Paul Stoffregen (the Teensy creator) extended the digitalWrite function to work for his ARM setup. He also extended the Arduino direct port calls (DDRA = 0x0F) to generate ARM register code when the board is set to Teensy 3 (and now 4). So when you write direct port register code in Arduino, for an ARM Teensy, it’s not really direct code anymore. This and the fact that ARM register bit manipulation works very differently, gives you the non-predicted results for your tests. Compile and run your test code on an AVR Arduino (UNO, Nano, Leonardo, etc), or a Teensy 2.0, and you should get very different results.

Should be possible to get same result by telling the compiler to unroll loops, however im not comfortable enough with compiler optimization to trust the compiler to actually unroll the loops i want to unroll, so either code it ugly or look at the dissasembly to make sure. :)

Hi again. I did finally get the code to compile, but the serial monitor did not show the text, only a bunch of questions marks.

Thanks for the great video. I tried your Code and I can’t get it to compile. What am I missing?

"dumps the flash and cackles* ez hack

You could add an RTC to the electronics and have the code be dependent on the time it receives the message. It solves the problem of desync.

"unrolling the loop" :)

The waveform of the last one looks extremely distorted, so it still seems like the bitwise is faster without sacrificing the waveform?

So you jam one of the signals and you store the rolling code which remains valid cuz it hasn't been used and then you're in....

If an incorrect code is repeated, Rx wont progress.. Hacker records 2 valid sequences and plays them back alternately. Rx progresses and looks ahead so it only takes once round the sequence and I'm in.

Maybe I misunderstood, the entire project only offers one function for a fully 4 button sender. If this is the case, I would suggest that instead of binary, we use fibonacci number base, 1 2 3 6, if you use this base 1 = 0001, 2 = 0010, 3 = 0100, 4 = 0101, 5 = 0110, 6 = 1000, 7 = 1001, 8= 1010, 9 = 1100, 10 = 1101, 11 = 1110, 12 = 1111 and the last button could be encoded into the last code sent, so you have 12,13,14,15 based on binary coding. If any transmitter sends any numbers above 12 in a sequence, you can lock it up.
