Cannot compile a plain simple union under AS6.2.1153
What does it matter that a non-standard header like avr/io.h includes a standard header like stdint.h? As far as I know, it's not disallowed by any relevant standard. Including...

Compiler bug!
Nobody said you are stupid.   Again, what value does k have on the STM32, and what value do you expect k to have?

What value did you expect k to have? What value does k have on the STM32? I would expect k to be 119 after that assignment.

Correct spelling? Diode ORed or OR'd or what?
I would argue that OR, as a function/operator, can be used a verb. In human language terms (or at least English terms), an operator (like OR, AND, ADD, MULTIPLY, etc) is the verb...
