Getting started with SocketCAN (can-utils) | ESP32 | Kali Linux Vmware Installation

[@romcm7duong853]

Thanks, it is very helpful and easy to understand. 🥰

[@kme8134]

You are pure gangsta. Thank you, very helpful.

Inspiring content. One day I will be an EV engineer!

[@yvanpearson7024]

This video was huge for me

[@bArda26]

Great video thank you!

[@Roottech25]

can you write code that tells the device on a can network to do something? that what is called bidirectionall communication in can bus. . a practical use is to send a message to a ECU in a car to actuate a selenoidse or turn on a fan.... it can' be that difficult

[@madusankaduwage8917]

Hi . Is any usb to can device support socketCan ?? Thanks

[@robfei-u6b]

the best can video in the earth. could you help create deeper tech video about how to parse can _info in different can node. thanks!!!

[@EV_engineer]

Thanks! I’ll consider the video idea

[@robfei-u6b]

Hi, in your Arduino code, I found you mention RTR packet (can.beginpacket(0x12,3,True), is it the bool True to active RTR, also could you explain why use RTR, and why in linux, i will get remote request?? thanks!!

[@EV_engineer]

Hi, I got this example sketch from this article: www.circuitstate.com/tutorials/what-is-can-bus-how-to-use-can-interface-with-esp32-and-arduino/#Remote_Transmission_Request_RTR This part addresses your question: "Just after sending a normal data frame, we will send an RTR packet requesting 3 bytes of data. beginPacket() function has a few overloads and we can send additional parameters as we need. For an RTR message, the third parameter should be true." As for why use an RTR, well, to request data from other nodes. Every node on the CAN bus that is not explicitly filtering messages from the source node will see this RTR request and can respond accordingly.

Any thoughts on CanOpen? I bought a couple USB-Peak-Can controller, which I understand is supported by SocketCAN.. but now I'm looking to see how to display data from a CanOpen device. I've seen some devices that use the CanOpen protocol (Guangcheng Technology thermocouple 8-way input KJST, GCAN-4128 , SM1810C CAN, CANOpen Stepper Controller PMC007, CANOPEN core board USBCANIO), but I'd like to first see if I can test using have one PCan device acting as the client (running for example CanOpen Magic), and another PCAN device running a CanOpen simulator (ex. canslave_sim or CANopen for Python). Assuming of course, I download/make a Device configuration files (DSF) or EDS file.

[@EV_engineer]

I haven’t used CanOpen before, but seems like an interesting video ;). I‘ve worked with ISO-TP, which provides network layer support over CAN.

[@bennguyen1313]

@@EV_engineer I'd like to try SocketCan but don't have a OpenMoko USB2CAN V3.3... I have a PEAK PCAN usb adapter. Do you think the VM/socketcan will work the Peak hardware? BTW, I tried booting a Kali Linux *LIVE* dvd I couldn't get can can-utils installed: apt-get install can-utils (unable to locate package error despite having internet connection) git clone htt...//gh.../can-utils (.git) cd can-utils make sudo make install Not sure why Kali doesn't automatically come with it.. perhaps there's a distro that comes with SocketCan already installed?

[@ingenuus2]

I think you know a lot about the Canbus. When will there be a working library for the Canbus for the ESP32S2, or does it already exist for Arduino?

[@EV_engineer]

Hi, there is a library! Checkout my video here: kzbin.info/www/bejne/kHnCdHapZpejqsk

[@jamgood96]

Any ideas on why, when I plug the device in and verify it shows up using `lsusb`, that it does not show up under `ip link ls`?

[@EV_engineer]

Are CAN HI/LO connected properly to the converter?

[@gobrbrr3558]

Can I use this type of connection to communicate with a Linux virtual machine running QML interface?

[@EV_engineer]

I'm not familiar with QML, but the interface here is just CAN over USB.

[@eriklethdanielsen3968]

why do you still run windows, windows is dead i have run Debian KDE sinse 2019, it works fine for ewrything also pcb design and writing software

[@mathewsjacob]

Great video, Thank you.
