Hi marco, this morning I cleaned the project, at the instruction: palSetPadMode(GPIOB, 0, PAL_MODE_INPUT_PULLUP) was accepted by the compiler.
Now the code and the pull-up function are working like they are supposed to do! I have no idea why yesterday were not!
Thank you very much for your valuable help!
PULL-UP Input Topic is solved
