Absolutely!! That is what I LOVE to do... Learn and share
I designed, built and programmed a CAN bus to SD card recorder. It uses an $8 ESP32, a $2 CAN bus transceiver and a $2 SD card module.
I simply plug it into my car and go for a drive. It records all the CAN bus data to the SD card.
On a manual transmission G37, it records close to 1200 CAN bus messages per second and on an automatic G37 with AWD, that jumps up to 2200 CAN bus messages per second. (Thanks again Kevin & Andy!!)
Then I use SavvyCAN to visualize the data, reverse engineer it and build a "DBC" file that defines everything. (well not everything... some items are very difficult to figure out!)
The CAN bus data is saved in a "SavvyCan" format, so it makes it easy to open it in the FREE and EXCELLENT SavvyCAN program.
I am 90% done designing an easy to assemble kit that allow you to do this without any electronic or programming skills. I think everyone should be able to do this for under $50 an not spend $300+ for the commercial CAN to USB/SD kits.
