Hello,
I wondered it writing / reading 32 bit values on a stm32 controller is atomic. The actual question is:
If I have an interrupt handler which writes a uint32_t value and an application which reads the same value, do I need to lock interrupt or mutex? If reading and writing 32 bit values is atomic there would be no reason to lock.
Thank you for answers.
