Initial project using STM32H745BIT3 supporting FDCAN

Hi: I'm a "newbie" to STM processors. I have a board with the STM32H745BIT3 processor on it. I'd like to get the board to initially communicate via FDCAN to my laptop. My laptop has a PEAK FDCAN device on it. Is there a base CubeIDE project or .ioc file out there that I could use to initially get a prototype project running to communicate with the laptop. Once I get initial communication working, I plan on trying to use the emotas CANOpen stack. Any comments regarding FDCAN communication on a H745 processor is much appreciated.

STM32H7 series

FDCAN examples for STM32H745 are here: https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/STM32H745I-DISCO/Examples/FDCAN

If you've installed CubeIDE or CubeMX, these examples likely are in the "Cube repository", already downloaded to your PC.

You'll have to adapt them for your board.
