CANFD / CAN USB Converter

Linux Support

Ensure the gs_usb kernel module is enabled:

sudo modprobe gs_usb 
sudo modprobe can_dev

Connect the device to the USB, and check if it has initialized properly

ip link list

There should be sth like this

10: can0: NOARP,ECHO mtu 16 qdisc noop state DOWN mode DEFAULT group default qlen 10 link/can

Connect UCCB device to CAN network.
Configure the device:

sudo ip link set can1 type can bitrate 1000000 dbitrate 4000000 fd on

Replace can0 with the name of your device and 500000 with the desired bitrate.
Bring the device up:

sudo ifconfig can0 up

Use the device with SocketCAN. For example,

 candump can0

For more tools, see can-utils.

Windows 10/11 support

CAN is supported out of the box with uCANViewer.2.0

For FD support on Windows CANFD converter on windows, you need:

1. Install WSL as described here
2. If you are on Windows 10, compile the latest kernel with CAN support. There is no full tutorial on this, but take a look at this page
3. To connect USB devices, follow this tutorial, but in short. Install USBIPD. Ensure that the device is visible in Windows in Powershell

usbipd wsl list

You should see a device like the one below.

 5-1    1d50:606f  cfuc, cfuc DFU interface                                      Not attached

Attach the device using the (pick your number from the list command, in my example, 5-1 )

usbipd wsl attach --busid 5-1

Now devices should be visible in WSL; check with lsusb

All stuff tools/sources/examples, etc, can be found here

Bootloader: The device supports a USB DFU bootloader for new firmware upload see dfu-utils tutorial.

Drivers: Device support gs_usb driver. The device is powered directly by USB

Embedded software: Embedded software is open source, and details can be found here

Hardware: Hardware is an open-source schematic, and PCB is done in KiCAD schematics here.

The total amount for your order does not include a customs fee/tariff. A tariff belongs to the buyer when applicable. Why don't we add tariffs to the product's retail price? - If all countries deducted the same tariff amount, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount, while some do not even charge. Therefore, we can't add any tariff to the product's retail pricing. Oz Robotics, manufacturing partners, or Suppliers are not responsible for tariffs. Please check the "Made In:" and "Brand:" labels on the product page to see the product's origin. The total amount for your order does not include any duties, import taxes, customs fees, and GST/VAT. The buyer must pay all import duties. If you choose not to pay the tariff and parcel returns, there will not be any refund. Please click here to see more on Tariffs.
