I noticed the screen recording portion is only HD. My apologies for this. I will fix this for the next video!!
Patrick, your teaching method is perfect for me.
Thanks
I really appreciate that. Thanks!
Good explanation.
You are a great teacher. Thanks for sharing!
Thanks for watching!
I liked it before I even watched it.....I knew it would be a high quality video ! Thanks for the content!
Yayy! I'm glad you liked it.
Vert well explained, usefull, straight to the point. Thumbs up!
Thank you!!
I love the Space Odyssey Hal part lol. Great stuff Patrick. I really enjoy your video series on STM32
Haha!! Thanks. I had a lot of fun making that video.
Great series thank you and keep up 👍👌
Thanks
Definitely informative and love the ending
Thanks!!
it’s 3:30am and i laughed way too hard at the beginning
I really appreciate the effort (and humour!) you put into these videos, it's great!
Since your videos are aimed at folks starting out with this type of programming I wanted to offer my 2 cents -- not criticism at all, just a couple of things that can trap "young players" as EEVBlog might say :)
Early in the video you talk about testing a register's value with a 'bit number' using the '&' C operator. This may trip up some because you don't really want to use the bit *number* here but its *mask* value instead. If the bit number is 7 for example you wouldn't want to compare with 7, you would want to use (1 CR & ADC_CR_ADCAL)'. Some people feel this is more explicit than comparing to zero, I prefer it because it seems easier to read.
I actually thought about that while I was making the video, but that gets into some scary territory for new folks. I will probably create a card in that video directing them to more advanced videos I made a while back, talking about truth tables, adding and boring binary numbers using masks. I have heard some folks say that this is hard, and there really isn't here that is hard, so I am giving them the easy way now and adding more advanced information later in a scaffolding approach.
On another note, when you suggested using the HSE, were you thinking I would add an external osc? I am using the HSI and multiplying that instead. I am uploading a video I made 4 years ago today or tomorrow that shows this working in the GND library environment. The HSE option did not work, but I think an interesting video of it not working yet, will come out of this.
@@PatrickHoodDaniel No, I didn't mean to suggest you should use HSE, I only meant to clarify that *if* you wanted to use it you need to 1) have the component on your board :) and 2) enable it in the RCC. At the time I didn't know what board you were using, now I've looked into the NewbieHack and know a bit more. I am not an EE ... but I wouldn't recommend putting a MHz oscillator on a breadboard -- stick with the HSI if you can. As long as the UART bitrate is not crazy high you should be fine with it. Use all the tricks at your disposal to work around the sloppy clock (oversampling for RX and bitrate tweaking for TX/RX) before going the HSE route. I think you said your application was transmit-only, which opens the door to generating your own byte frames. You could do this either using bit-banging or, on the STM32F it's fairly straightforward to drive a GPIO pin directly from a timer-driven DMA: program your byte frame's start + ones & zeroes + stop into RAM and DMA that to your GPIO pin, using a timer to control the bitrate. What fun!
@@PatrickHoodDaniel At first I sort of understood your logic here about staying away from the "scary" stuff and building up knowledge like scaffolding, but after I watched your video a second time I think the video does deserve a follow up or on-screen corrections (whatever those pop-up text messages are that you see all the time).
If you're really trying to build knowledge (and I believe you are) then what you present should fundamentally be correct. If a newcomer is just starting to figure out masking like this and they see you tell them to compare with bit numbers it's going to lead the newcomer astray and probably frustrate them more. It's a great idea to layer the material and not dive into tricky topics too soon, sure, but if you do choose to cover 'while' loop conditions then what you present should be fundamentally correct, even if it's not a thorough treatment. Saying "!= 0" is the same as "== 1" is just plain wrong.
You wrote ".. and there really [isn't] anything here that is hard..". If I've quoted you correctly, then I disagree with you. This register-based programming *is* hard. I do this for a living and can assure you this is exactly where everyone, professionals included, make mistakes time and time again. It's the very reason companies like ST Micro invest countless $$ into developing tools like their HAL libraries and CubeMX/CubeIDE code generators.
Thanks, it is another great video! I am used to spend time in PM0214
(Programming manual) for the flow of operations looks like your book is becoming my go-to reference ;-)
You just demystified bits manipulation. For people coming from higher level language, this is unavailable! Thanks 👍
You are so welcome!
more in-depth information about AVR is here, thank you sir. but I haven't found on youtube how to long press the button on the AVR, can you give an example video .. @hope
Great video, but I have to correct something...
(register & bitnum) == 1 will most likely never be true. Example:
1111 & 0100 = 0100, which equals 4, not 1. You can test if it's not zero, but you can't test if it's 1.
Hi, I'm a fan of your videos and glad to see you continuing to make more! So, I'm coming more from the software side. My electronics knowledge is very weak. Do you have any recommendations for how to build that knowledge for a microcontroller-embedded system emphasis? I find that going through an entire basic circuits book is not practical because my goal isn't to really learn all the integrals and whatnot. Its to learn the key aspects of microelectronics that do come up when I'm reading datasheets or trying to program features of an IC or possibly trying to design an embedded system (I know some parts of what i'm saying are contradictory). If you can provide me any direction for developing hardware knowledge, I'd greatly appreciate it. Thank you.
I would just continue watching these videos as I will be explaining the circuits as I use them in the projects. If you need to understand how a particular circuit works in a pinch for a specific project, RUclips never fails. You can learn every aspect of electronics from other RUclipsrs as well.
@@PatrickHoodDaniel thank you!
I really like your goal of simplicity, for instance removing the code bloat introduced by the IDE - I like that. However, in this video you left-in the SystemClock_Config(). Was that 100% necessary - or would the power-up clock defaults be okay without SystemClock_config()? In otherwords can SystemClock_config() be removed without any *unpredictable* results?
It may actually not be necessary since the default values in the microcontroller already start the HSI internal clock. If you want to change the clock through the ioc file (CUBE MX), you will still need the SystemClock function. If you set the registers yourself, there is no need for the SystemClock.
This is awesome. Do you have a pdf we could purchase. I don’t have kindle and paperback doesn’t give me the search function a pdf allows.
Thank you.
Unfortunately not. PDF files get distributed very easily. If there is a way I can figure out how to keep pdf files safe from being distributed over the internet, I will make it available.
Hi, me again,
In this video you exactly show what's I find confusing. There are so many steps to just turn on/off a LED.
Mode, Speed, pull up/down and Set/Reset.
My understanding is, each pin has several different functions and we need to specify which one we are using. Are all ARM uC the same?
Other question, when you talk about the register, are you referring to the address? Ex: 0x25
Thanks again for taking your time to record and explain.
I am having a problem with the ST-LINK V2. STM32CubeIDE keeps saying I need to update the firmware for the ST-Link and won't let me program the chip
I am working my way through your book. I was wondering if there is a code repo for the books code. I have arthritis and typing can be painful. Also, do you want notifications about erors/typos,; and if so where?
I don't currently have a repo for the code. The code was developed to serve as content for RUclips and as I was writing the book, I didn't think of putting the code on Github. I would love if you could provide me any information you see could improve the book. I just created a FAQ that can build over time for the book here: buildyourcnc.com/FAQ/14935. Thank you so much for this suggestion!
Sir, it's hard to see the editing code from my phone chell, if... larger font it will be great, aniway this is great video, loved it so much & sure, I'll check it out on my laptop for biger screen. Thank you for dis amazing lesson.
Yes, I'm going to work on that. Thanks.
For coding, can we use anyone software like Visual Studio Code or Notepad++ instead ? Great Thanks 👍
Yes,but it is far more difficult to setup. The STM32CubeIDE is quite easy.
Excuse me but there is black gaps at left and right side so we can't see the code clearly. Can you make full screen video next time please ?
Yeah, I will do that next time. Thanks.
Please zoom in to your code so your videos are legible even on mobile devices with smaller screens!
😄😄😄
Arduino so simple......just pin mode and digital write and is done
Enjoy your Arduino. Arduino has its place, but I don't focus on Arduinos. I would rather focus on a development that is best for production.
With just 2 lines of code using xor portx we can toggle that port
Has anybody watching this video seen "2001: A Space Odyssey?"
No but I knew of a company named HAL that made an Intel 4004 support board. Awesome chip and loved playing with it.
@@okiopie you must watch that movie. The HAL segment in the video will make a lot of sense. It's a classic.
Yes, best film ever, Stanley Kubrik was a genious. You will end in the deep space using HAL
HAL == I-- B-- M-- spooky
A cool project idea, build a HAL voice synthesized ;-)
Daisy, Daisy, give me your answer, do.
The STM Links are out of date
It appears that RUclips put three dots (elipsis) cutting off the link. I have replaced them with shortened links. Thank you so much for letting me know. It looks like I will need to do this for all of my vidoes.
That's a whole lot of code and research just to blink an LED.
Thanks for the video.
BTW: Your book is very difficult to read on Kindle, unfortunately. It has a very fine and light gray writing, so that you have to strain very much if you want to read it.
Hmmm... That is not good. Can you tell me what specifically is wrong so I can make the necessary modifications? Font size, colors, margins, etc.? Thanks
@@PatrickHoodDaniel I am not a technical Kindle expert. The problem seems to be, that your book does not use the font, that is configured in the Kindle and what all other books use.
Normaly, I can configure, what font the Kindle should use. All other books follow that configuration. But your Book uses another font. It is a finer font and, even worse, it has a light gray as the font-color and not black, as it is used by all other books.
But I do not know, why this is the case, I do not know, how the Kindle exactly .works.
sorry to say but, number 5 Tutorial the 'the 4 basics to control all' is out of focus when looking at program.
Yes, I mention this in my pinned comment. My apologies for this.
I know these video's have been out for a while however, Why when typing in code is the screen so much bigger? Secondly you say for beginners then charge off leaving them behind. Make up your mind, for begginers like me, or for those already up the ladder.
It would be great if you did another, skip the IDE you did that well, but remember idiots like me, trying to grasp it, before charging off, with a screen so tiny and possibly a little out of focus. In saying that, when you show the chip data sheet it's great.
All in all bless you for trying at least, I have found trying to find a good RUclips course frustrating & proliferated by Asians speaking poor & broken English. Keep on trying. Thankyou. Sam
I have a slew of videos that cover the basics and a book that will also get you up to speed. These videos are a continuation of the more beginner series and the book.
