  1. What are the hardware registers that cause the LED to turn on and off? (From the processor manual, don’t worry about initialization.) -> copy paste the hell out of it • User LD3: The orange LED is a user LED connected to the I/O PD13 of the STM32F411VET6.

    • so its GPIO port output data register (GPIOD_ODR) -> question to self !!! wtf is 8.4.7 GPIO port bit set/reset register (GPIOx_BSRR) (x = A..E and H)

  2. What are the registers that you read in order to find out the state of the button? -> coppy pasteee

    • B1 USER: User and Wake-Up button connected to the I/O PA0 of the STM32F411VE
    • GPIOA_IDR ?

3.Can you read the register directly and see the button change in a debugger or by printing out thes value of the memory at the register’s address? * yes i check through the register watch part
