EDIT - after half a day more, I'll have to ask the stupid questions.
1: Can a STM32F33 Nucleo F334R8 be used to set up a CAN analyser?
If yes, HOW?
I have installed STMCubeIDE, ArduinoIDE, SavvyCAN, jonvolks GVRET files and I don't know what else.
I have attempted Damiens simple Command update via his vimeo video, but the device is not detected at the end (all the rest is as per his explanations)....
I tried to install the GVRET files into ArduinoIDE as per another website I fell onto in the early hours of the morning, but get message error at the end

Should I buy an Arduino Due and get on with it? There are examples of STM CAN programmes, but I assume they will not work without the magic GVRET files....

RetroZero wrote: ↑Mon Jul 31, 2023 8:45 pm OK, looks like it will be that way then. I felt like I was so close. I got the Nucleo board to communicate with my pc and I learnt how to upload examples like making an LED blink (need to find a LED to confirm it worked) but the comms LED was flashing during the download, and a positive confirmation was received at the end. That's a giant step for me!
I'll play with ArduinIDE to see if I can do the same, even if only for practising, but my aim is to get CANning asap. Would like to implement an onboard OEM charger....amongst other things. There's a certain ID4 battery that requires data packs from a host, would have liked to help out ,but my setup and (lack of) knowledge has set me back.

Here I found the data sheets:

I saw this before going and getting into Mooc's on how to make a CAN logger etc. As I don't see it on Damiens webshop, and I am too stupid to get onto Discord, I assume it's not yet up to a plug-in and play status. I have made HUGE steps for mankind - I made the internal LED on my Nucleo board blink, and then coded and external LED to switch on. This is big stuff for me, so next will probably be reading CAN or something. And yes, I could just buy EVTV one, but that's too easy.

Over at savvycan.com there is a binary "updater" which actually just flashes precompiled firmware to the board -> https://www.savvycan.com/GVRETupdate.zip you can use that on basically any Arduino Due based board but as has already been mentioned, the compiled version does expect EEPROM which the Due did not have unless you got the EVTVDue that they sell which does have EEPROM on it.

And, I am aware that perhaps getting all the tools working and getting SavvyCAN connected might not all be the simplest thing ever. Compiling it all yourself is probably quite the adventure. It's tough for me to get a good baseline of where all the pinch points are because I can compile it all in my sleep at this point. But, even I get frustrated sometimes when trying to get various devices hooked up and working. I obviously have a lot of EVTV boards but I also use PeakCAN and Kvaser tools, I have the Microchip black box thing too. I have lots of CAN adapters, the PeakCAN and Kvaser are the easiest to use but the most expensive too. Really, for me the coolest one is either an EVTV ESP32 or the related Macchina A0 - both of which can connect to SavvyCAN over wifi. The A0 is especially cool in a car where you can slap it onto an OBDII port and away you go.

And, SavvyCAN is probably quite the mountain to climb because it started out as a tool for me (and a way to learn QT programming) and just kind of evolved over the course of years into having everything including the kitchen sink. There's probably like 4 ways to send CAN traffic for instance. You can use the fuzzing window, the frame sending window, you can write scripts in the script window, you can replay captured traffic. Some of them overlap but everything exists because me or someone else wanted to do something it didn't do yet. I wish I had more time to work on all the CAN tools but recently I just haven't been able to. Still, there is some progress. Be sure to check the "continuous" build if you want all the newest toys. It's automatically compiled for all three operating systems supported. Technically people compile SavvyCAN for Raspberry Pi too. But, I don't have compiled binaries for that.

EVTVDue Microcontroller for $100 bucks, think of it as thanking them for SavvyCAN

OR, get their dual channel board

cause you will spend that much to roll your own as this is the only decent shield like CAN adapter for the Due board COPPERHILL TECHNOLOGIES Dual CAN Bus Interface For Arduino Due With Extended Power Range and runs $50 bucks alone
