The biggest problem for many of us is reading/understanding the data sheet (RM0008) which is not bad but then how to write a line of C code that reads or writes those configuration registers. Often it requires sifting through many abstraction layers/header files, finding naming conventions, trying to decypher unions & struct & pointers, etc. Also, knowing the necessary sequence of things like a peripheral clock must be enabled in some far-off register before the IO will work. This is great stuff!
Ken Wallace I agree the manuals can be cryptic at times and procedures for proper setup are often not well documented. For this type of programming the only header file you need is the one with all the bit and register definitions. It just takes practice and patience , lots of hair pulling too to get things working. I have taken several courses most on Stm32 so I completely understand where you’re coming from. I would definitely like to do an updated series of these tutorials
Ken Wallace I will admit I do find my self using Stm32 CubeMx a lot for routine tasks like setting up the clock and advanced peripherals where the “proper steps” are unclear to me. And then the rest of my code does not use the abstraction layer
Eddie, thanks a lot for these videos. They are really good and I'm telling my friends to watch then. It would be really nice if you could do other videos about timers (with PWM), counter, interrupts and ADC too
i was in the hospital 2 times in one day with an asthma attack , it definitely was the place i was living in at the time. Now m,y breathing is a lot better albeit not perfect.
16:30 After you coded the microcontroller some magnetic area or something like this can influes your microcontroller and it can make your IO 1 or 0. If you use lock register for your important pins then it will be better for your circuit.
Hey Eddie, finally a tutorial with a good accent, fast and clear enough to understand. Please make videos longer and don't talk slower, I like it when you speak fast.👍. Also, use the pen more. Thank you.
If you are controlling a CNC machine (or other large and dangerous device), you need to be sure that it does not misbehave and kill people even if the software becomes unhinged. The ability to lock output bits is just one more layer of security to prevent these disasters. It is true that running random code is unlikely to write deadly values to a port pin, but it is unlikely times unlikely to unlock the pin and then to write a deadly value to it.
@@EdwinFairchild The STM32 port lock bits. You said you "couldn't think of a reason to lock port bits; if you don't want the bits to change, simply don't write to them." (or something close.)
@@byronwatkins2591 ahhh true. And you are absolutely right there a scenarios where you would want to know the exact state of the bits and not have them change. !!!
@@EdwinFairchild ok Can you share video link or pdf in which d smt32 discribed from very basic Like what is HAL Option for coading , which is better How used it easy way Best and easy method to use it
@@Shubham-9996 I do not use much HAL , and you can watch these videos to learn how I do it , why make a pdf or another video if this series already describes everything
Hi man, thanks for awesome explanation. Can you please make one vedio on clock tree. As i was going through that...but faced a little difficulty in understanding clock tree.
Eddie, first of all let me thank you for all the time and effort you are putting on these videos. I've been wanting to learn hot to program microcontrollers at a register level for quite a while now and if it had not been for your videos I'd still be lost wondering where to begin. I was just wondering if I could ask you a couple questions which might be kinda dumb :s I understand the world Lenght one can transmit can go from 8 to 9 bits, but. What happens if we want to send a string out? Something like the AT commands for a WiFi module.
At commands are just multiple characters , you just send the "A" then the "T" and so on... The receiving device will now that the commands come in one letter at a time. As far as the transmitting device you just loop through your strong array start from index 0 till the end . That's it
As long as any communication protocol is serial ( i2c, SPI , UART etcc) it happens 1 character at a time. The first hint should be only 1 data line. Now if you have 10 data lines then you can send 10 characters at a time that is parallel communication
I think this code doesn't work anymore, maybe due to changes in new Keil version or due to some step missing. Mine doesn't blink at all, however LED is always litup and only blinks when reset button is pressed. Wonder what is the fix to this..
what does your code look like? are you trying to blink using a foor loop delay? is the for loop variable a volatile type otherwise its getting optimized out for being an empty loop..
There no gpio library, this is about learning to write your own library so you can really learn how to use the microcontroller, instead of calling a function that someone else wrote
Mr.Sandman lmfaooo true, allergies man!!! But I’ll keep that in mind, I’m hoping to make a video tomorrow but right now I’m in bed with allergies yet again
The purpose of telling someone in a long ago recorded video to stop sniffing is a fools errand at best. Maybe if you replay the video after your comment he stopped

Never has there been more snot involved in a really useful tutorial. Hope that cold got better :-)

Hey, one question... On the input, how do you select between pul-up and pull-down? I see no register for that...
When it is configured as input, to select pull up or down you simply set the pin high or low.
When we want to make a pin output, is it needed to settings registers ODR after CRH (suppose pin 10) ? By the way Thank you :)
Do you used HAL in this series
No Hal
@@EdwinFairchild ok
Can you share video link or pdf in which d smt32 discribed from very basic
Like what is HAL
Option for coading , which is better
How used it easy way
Best and easy method to use it
@@Shubham-9996 I do not use much HAL , and you can watch these videos to learn how I do it , why make a pdf or another video if this series already describes everything

Oooo
Sorry sorry
I haven't watched yet, I am thinking that this series is high level
I am too much freshers
@@Shubham-9996 my videos are all very low level programming st the register level
Where can I find this kind of datasheet? My datasheet does not include some parts in your video! Thank you
Its a reference manual...
Hi man, thanks for awesome explanation.
Can you please make one vedio on clock tree.
As i was going through that...but faced a little difficulty in understanding clock tree.
Hey check my blog I did a post on that, I know its late my bad haha

how do you make this files in use libraries folder
How can we do this by using proteus?I couldnt find to upload the code to the Stm32f103c8 in the proteus.
ilker aykut I do not know what proteus is, I’m sorry
You can make your own device, Its more trouble to know how, but also can work for you in another projects, serch on youtube
Good turotial, thanks for making these videos.
Thanks for detailed explanation... thanks a lot ...
Wow this is great. Nicely done
Is the website dead? Thank you BTW. I'm coming from PIC16 MCUs
yeah i have not paid the website hahaha i need to find a free place to host it just to keep it up

Nice video
hey man i love your videos but you can't sniff that hard in your video. just a bit gross. love the videos though, please keep them coming
Mr.Sandman lmfaooo true, allergies man!!! But I’ll keep that in mind, I’m hoping to make a video tomorrow but right now I’m in bed with allergies yet again
Are you having a cold, I see you blowing your nose continuously
this was so many years ago man, you have to go back in time and ask him
for love of Jesus stop sniffing!!

Yeah, go easy on the nose candy...!
