I was looking through internet for exactly something like this. Everywhere are just tutorials which are based on "HAL library magic". I have enough magic in high level software programming. I started programming MCUs for sake of reducing number of black boxes. Your videos are awesome!
I have a question about STM32L1 Discovery Kit Lab 9 (ADC) on your website is that: i want to do some thing cool: b) Use the potentiometer to control the brightness of a LED. I used TIM4 for this task, but it did not work. Can you show me where is the problem? Thank you very much!

You don't need to change the GPIO modes. They should be fixed to the output mode. To switch to a different output pattern, you only need to update the GPIO Output Data Register (ODR).
@@embeddedsystemswitharmcort9051 I wonder why only the logic 1 make the output floating, it there a reason ? It looks easier to make the output floating in both logic 0 and 1

Those figures along side the explanation is making things much easier to grasp. thank you so much for your effort, keep up the good work
Thanks, will do!
Your videos are very good to learn basic concepts of microcontroller, thank you
In slide describing GPIO output: push-pull, the controller in the picture is inverter, right?
Sir, Thank you for making this video.
Where can I learn such command like GPIOB -> MODER &= ~(3UL

I have questions suppose we can generate led pattern which gpio mode use automatically next pattern generated.
Sorry. I cannot understand your question. Can you rephrase it?

How to get the book in China?
Short and clear thank you
in opendrain configuration for logic zero , output is floating and for logic one output is grounded.. isn't it?
No. logic 1 makes the output floating.
