Hi team thanks for your coperation with me. I have been trying to enable MDIO peripheral At one of the STM32 EVK kit(NUCLEO-H7A3ZI). What i could see, when i have gone through the MDIO's official block diagram. The MDC pin drew as input and MDIO as b...

Thanks all of you. Spent some more time for my question.First of all i will check it once with your instructions.I have only one option to view output.first of all create the clock frequency and run a timer then toggle a gpio pin. The toggling de...

Any other difference did you get.When i use or operation it will not over write previous state. I thought this like.

Sir I have another doubt?I will give you two different situations?1st.i uploaded my cobe on stm32 through system Boot loader method.2nd .I uploaded my code on stm32 through flash memory boot mode.My doubt is both methods store the main code in same ...

How to generate MDC clock?

Hi all, i would like to make a my own bare metal code for stm32f401ccu. Here i have given my code. But it's not showing correct clock frequency. Anyone could you pls check it for anything missed or etc...

hi guys, I have created a simple led+tim2's program.when debugging that code i get fine delay but unfortunately won't get correct delay after reset or power on.

when boot0 pin low mode my timer program works fine and get correct delay but after the reset the timer not working and no blink led what are the reasons?

i have written a led blinking program with as per my knowledge but i couldn't reach output so guys who can clear that? MCU- STM32f401 clock input -25MHz External clock output -80 MHz with pll configuration
