Does Registers work in STM32Cube Programmer?

KMoel.1 · ‎2022-07-25

I am trying to use Registers in STM32CubeProgrammer to change the setting of GPIOB, but whenever I change a value. it just gets changes back to the value it had before! Is this because Registers is still in BETA or am I doing something wrong?

I changed to an other target HW and now it works, so it must have been an issue with the HW. Thank for the help

Works for me. Did you press Aplly between Write and Read?

It is when I press Apply that the value changes back to the original value

What chip?

Which register(s) have you tried?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

STM32L476

GPIO8 MODER8, OT8, ODR8

Present details of the chip you're using.

Go over the exact sequence you're using.

Make sure clocks are suitably enabled, otherwise peripheral registers will stick at zero
