5.1. Work Mode (Default)

In Work Mode, the Boot Switch should be in the OFF position. The adapter will operate with its currently installed firmware. By default, the SH-C31A comes with candlelight firmware, which supports standard CAN frames but not CAN FD frames.

To use the adapter in Work Mode with software like Cangroo or BUSMASTER:

  1. Ensure the Boot Switch is in the OFF position.
  2. Connect the adapter to your computer and CAN bus as described in Section 4.
  3. Open your preferred CAN analysis software (e.g., Cangroo, BUSMASTER).
  4. Configure the software to recognize the "candleLight USB to CAN adapter" or similar device under Universal Serial Bus devices.
  5. Initiate measurement or communication within the software.

5.2. Firmware Update (DFU Mode)

If you require CAN FD functionality, you must flash the firmware to slcan firmware. This process involves putting the device into DFU Mode.

  1. Enter DFU Mode: Move the Boot Switch to the ON position.
  2. కంప్యూటర్‌కు కనెక్ట్ చేయండి: Plug the SH-C31A adapter into your computer's USB port. The device should appear as "STM Device in DFU Mode" in your device manager.
  3. Access Firmware Updater: Navigate to the official CANable 2.0 firmware updater webసైట్: https://www.canable.io/updater/canable2.html
  4. ఫర్మ్‌వేర్‌ను ఎంచుకోండి: న website, select the desired firmware (e.g., "slcan with FD support") from the dropdown menu.
  5. ఫ్లాష్ ఫర్మ్‌వేర్: Click "Connect and Update" and follow the on-screen prompts to flash the new firmware.
  6. Exit DFU Mode: After successful flashing, return the Boot Switch to the OFF position. Unplug and replug the device to start with the new firmware.
