Cannot communicate with USB-CAN Analyser

[Aahlad_Adiraju]

Hello,

This is Adiraju, I am currently working as an intern at LANG AG Germany in the R&D department, where I am a part of the project which tries to extract CAN BUS data from a battery pack.

We have bought the product USB-CAN analyser and were working on it, but unfortunately we are not able to see the CAN BUS data. I have followed all the instructions like setting up the baud rate and rechecking it with the COM port in the device manager. I can see the red LED light up whenever I try to send a fame but cannot see any received frames (Loopback and silent mode). I even checked with Normal mode but whenever I set and start I can see the Red LED blink once but there is no output visible even though the green LED is blinking (bit rate of the CAN BUS is in accordance with the battery pack i.e. 500kbps).

Could you please help me with this issue, since we want to make use of this module for analysing the data for Quality Assurance (using a windows PC and a Python-can module).

PS: Can I use Python-can module to extract the data (if so what should be the bus type)?

Thanks and regards
Aahlad Adiraju

Hi there, have you tried ?

@salman

for the USB transfer CAN follow these steps

1. Insert the USB transfer CAN, install the driver

2. Open the USB transfer CAN epistatically machine application, choose COM port (port from the device manager inside port saw that is CH340 USB transfer CAN port),

Click on the open, according to the practical demands setting CAN baud rate, frame type, filter ID, mask ID etc, click CAN set CAN be used

It’s weird but once connected you can change the ID… afaik.

I have yep followed it and all works but can’t set device id

Is it in hex or decimal?

Also don’t understand the two option in the software which are

Receive id not uploaded
Only upload configured id

There is then disable and enable option at bottom of it

Hi there,

I don’t have one to test atm but it should be Hex if memory serves me, Hopefully seeed ENG will comment. I have seen this question before.

If you choose only configured , then It’s set by software. YYMV
