DSD TECH SH-C31A USB to CAN Adapter with FD Support Based on Canable 2.0

Able to easily use the can-utils package and verify operation using a scope with built in CAN decoding.

I purchased this to work with Windows and a Jetson Nano to work with CAN Bus data. for both windows and Nano/Linux the device did not install or there where no drivers. Tried to flash the Candlelight firmware, still was not able to use device.

As delivered, this product is a 3 out of 5. It is not a plug and play experience on Windows (I did not test under Linux). You must re-flash the device with the official slcan firmware on the device before you can use it in a Windows environment. I would give five stars if I didn't have to an hour or so figuring out why the device was not working. Splitting the difference, I give the device four stars.The unit I received had a version of candlelight firmware that I couldn't get working. The red LED, and a single green LED would light. The device would have a yellow triangle next to it in the Device Manager. It would not be recognized by Cangaroo. I tried the gs_can drivers, various drivers from the canable.io documentation, and nothing seemed to work. There always seemed to be some fault in the USB connection.The "web" updater other reviewers are referring to did not seem to work for me.Here is how I resolved the problems and got the device working:-Download the most recent slcan build for Canable 2. The file will be called "canable2-b158aa7.bin" and can be found at canable.io/builds/canable2/slcan/. (This is accurate as of January 19, 2024. Newer builds may be available when you are reading this with different file names.)-Download and install STM32CubeProg from ST's website. It is free.-Set the "BOOT" switch on the SH-C31A to the "ON" (down) position and plug it in to the PC.-STM32CubeProg will detect the adapter connected in DFU mode.-"Connect" to the device using the green Connect button in STM32CubeProg.-Load the .bin firmware file into STM32CubeProg and download the file to the SH-C31A using the default settings.-When complete, "Disconnect" from the device in STM32CubeProg by pressing Disconnect.-Remove the device from your USB port, set the "BOOT" switch back to the "OFF" (up) position.-Plug the device back into USB and it will be recognized as a COM port.No driver installation is required. It will be instantly recognized in Windows, and visible in Cangaroo's adapter selection. The red LED and both green LEDs should light immediately when the device is plugged in.In terms of performance with the correct firmware, the unit is excellent and I'm very pleased with it. It's an easy 5 stars. The form factor is decent enough for occasional use, but I would have preferred a female connector for a USB cable, instead of having the whole device plug into a USB port, making it awkward to use with a laptop in a vehicle. The removable terminal block connector for the CAN connection itself is great.

同封されていた説明書通りにソフトをアップデートしました。ArduinoのCAN busシールドでsend_ramdomから、cangarooで通常のCANの動作確認できた。CAN FDは未確認。適当な基板がなく思案中。CAＮトランシーバーをVIOのあるものに変更して、VIO＝3.3Vとして欲しかった。
