Arduino for STM32

I would think using CubeMX for setting everything up and looking at registers would expose the problem.
Are you sure the led your trying to blink is working?

Sorry can't help since I have not used can.
I can answer the LL vs HAL. The LL drivers are a self documenting interface to the register manipulation.
Unless you know the details of can the hal drivers will probably be more useful.
The hal is higher level and take care of some of the details for us.

Here is a link to a video regarding the 180 sensor. If it is similar to the 280 then it could be useful.

Welcome, yes the stm32 family can be scary coming from the 8 bit micros. You'll get used to it, mainly they have the same peripherals but more bits and more functionality and especially awesome more memory . ST writes excellent documentation which helps get up to speed faster.

Welcome, my first mico was the motorolla 6809 and I programmed it in assembly language while going to college way back in the day.
Your projects sound interesting.
Have fun.

Interesting history. I am glad ST decided to write their own core as I am familiar with there SDK. I have not used Rogers or any other core so I would use the "official" core. Thanks for your insight into this kind of confusing topic.

Thanks Ray, that is good news. I am assuming I will still have access to the HAL and the low level libraries using the stm32 core correct ?

Does using the arduino core also give me access to arduino libraries written for other devices like tft displays, etc...?
I am currently using MxCubeIDE and I am comfortable with it but I am wondering if by using the arduino core I
also get the benefit of not having to write code from scratch ...
