USB-CAN converter software manual

The USB-to-CAN converter is a software developed by Damiao Technology that allows for visual transmission of CAN protocol data packets via a connected debugging module. Using this software and the debugging module, CAN protocol devices (motors, gyroscopes, etc.) can be debugged very easily.

1. Download software​

https://gitee.com/kit-miao/dm-tools/blob/master/USB%E8%BD%ACCAN/%E4%B8%8A%E4%BD%8D%E6%9C%BA/USB2CAN_2.0.0.3.exe

Download USB2CAN_2.0.0.3.exe from here.

Click [Download] and wait till the download ends.

Open the software and enter the software interface.

2. (Debug module) (Hardware)​

Sending CAN protocol data packets via USB to CAN requires the use of the official USB to CAN module from Damiao Technology.

Purchase link: https://www.switch-science.com/products/10933

The debugging module requires a Type-C to USB-A cable with data transfer capability to connect to the computer. The USB to CAN software requires a USB serial port.
Please ensure that the CH340/CH341 driver is installed on your computer.

The debugging module's CAN interface is model GH1.25-2pin. You can modify the wiring or add an adapter board according to the receiving device's interface.

Note:
The correct CAN pinout: CAN_L connects to CAN_L, and CAN_H connects to CAN_H.

After connecting the debugging module to the device, open the USB to CAN software.

3. Using USB to CAN software​

3.1. Basic function usage​

  1. Open File
  2. Save Current Sending/Receiving Data
  3. Clear All Current Sending/Receiving Data
  4. Counter
  5. Firmware Upgrade
  6. Version Information and Discussion Group

3.2. Serial port settings​

Please select the COM port connected to the debugging module. If not found, click refresh in the lower left corner or check if the driver is installed.

  • Baud rate: 921600
  • Data bits: 8
  • Parity: None
  • Stop bits: One

Keep these parameters at their default settings. After setting, click the link in the red box in the lower left corner to open the serial port.

Connection succeeded, the Disconnect icon in the lower left corner will flash red and green.

3.3. CAN communication settings​

1​

  1. The baud rate for communication with the device is 1000kbps by default. Please set it according to the device's baud rate settings. Currently, the following baud rates are supported.

After selecting the corresponding baud rate, please click [设置 (Set)] to complete the update.

2​

Frame ID: Specifies the ID to be sent to the device. Users can modify this; the unit is hexadecimal.

3​

Send Data: 8 bytes of data sent to the device. Users can modify this; the unit is hexadecimal.

4​

DATA递增 (DATA increment): When checked, if the number of sends is greater than 1, the data sent will automatically increment by 1 each time.

(e.g.) if the data sent is

01 00 00 00 00 00 00 00

and the number of sends is 2, the data sent will be as shown

01 00 00 00 00 00 00 00
02 00 00 00 00 00 00 00

When the data reaches FF, it carries over to the next bit.

(e.g.) If the sent data is

FF 00 00 00 00 00 00 00

the next sent data will be

00 01 00 00 00 00 00 00

and the next sent data will be

01 01 00 00 00 00 00 00

ID递增 (ID increment): When checked, if the number of transmissions exceeds 1, the frame ID will be automatically incremented by 1 for each transmission.

5​

发送次数(Number of transmissions): You can select how many times to send data to the device after clicking send. 定时发送(Send interval): When the number of transmissions is greater than 1, the interval between each transmission.

6​

帧格式 (Frame format): Frame format: You can choose between standard and extended. Depending on the device's frame ID.

帧类型 (Frame type): Data frames and remote frames can be selected, depending on the device's CAN protocol.

7​

发送 (Send): Click to send CAN data.
停止 (Stop): Pause sending.

3.4. CAN send and receive interface​

After clicking "Send," if the CAN data is successfully sent, the status will display "Send Successful." If it displays "Send Failed," please check the serial communication, CAN wiring interface, and receiving device for proper functioning.

If the device returns CAN data, the received data and parameters will be displayed on the interface.

3.5. Serial port​

USB to CAN converters can also transmit via serial port. Connect the device through the GH-1.25-3pin interface on the debugging module. Note the pinout: GND to GND, RXD to TXD, and TXD to RXD.

3.6. CAN load​

USB to CAN converter allows for real-time monitoring of the CAN bus load.
