Nice video Phil. Surely still some quirks in the STM32WB stuff. For all the people doing home automation out there, would be nice to see a similar video to do the same with ZigBee, and then show your bluephil in home assistant :)
Hey Phil, loved your video! You’ve inspired me to learn PCB design and stm32. I would like to learn more about sub-ghz using c1101. Can you make a video on that? Love you Phil ❤
For some reason you tend to always make videos about topics I'm currently dealing with. I'm trying to add Bluetooth Audio to my car's stereo. Since buying a new stereo is boring and the current one also doesn't have an AUX IN, I decided to make an protocol emulator for an optional CD changer. That already works with an Arduino and a cable. I tired to get it BLE audio to work with an ESP32-C3, but I had no luck. I couldn't find any documentation or examples on BLE Audio, not even in the IDF. Only A2DP, which I don't want to use because it sounds quite terrible. So I guess I'll give the STM32WBs a chance now.
@@GoPaintman It's a Ford RDS 6000 CD stereo. TL;DR; I found existing projects that implemented the necessary parts of the protocol, and one of them also had scans of the original specification document. I found a pinout for one of the rear connectors that was unused on my car. The names looked like AUX related. Simply feeding some audio signal into it did nothing. Looking further I found that CD Changers are a thing and I figured out that ACP+ and ACP- are supposed to be some data communication pins. Searching for Ford ACP lead me to a lot of existing projects, even dating back to the pre-arduino-era. I wasn't completely happy with the implementations I found, I even considered buying a CD Changer from Ebay to reverse engineer the protocol. Then I found the original specification document in a project named "Yampp3".
Is it possible to build a communication between two STM32WB55 just like (or at least as fast as and as reliable as) the ESP now by espressif but with lower power consumption? The scenario i'm looking for is one STM32WB55 as a sender (controller) and an other STM32WB55 as a receiver (like a drone or robot).
hi phil great work ,you are an inspiration to many engineers .would you please tell me which software you use for screen recording and secondly which software you use for removing background mic noise
it is nice🎉 it’s a great video to start this board. Could you recommend some nice tutorial for Bluetooth stacks , maybe some websites or books. Thanks 🎉🎉
First, as always thank you for such a great tutorial series. I was wondering if you’ve tried Zephyr RTOS with STM32WB, and if so what you thought of it? Cheers !
Hi Phil, great video with a lot of very useful information - kudos to you. Out of curiosity, how much time have you spent before running the ble demo? I mean you have a ~34 mon video but I suspect the real time is rather months as opposed to weeks. Am I right ?
@@PhilsLab Thank you for the reply. The question was asked in the sense of how much time you have spent dealing with the documentation, st support (thread digging, customer support, etc.) and assuming you have no prior knowledge of the ST's μCs (which is not the case since you're using these for a very long time now). As a hobbyist, I'm interested in the overall timeframe of the learning curve as I find their development environment very interesting. Thanks for the 2 previous videos too, they are awesome.
Do you have any low-power designs where the STM32 runs from a coin cell (eg 2032), whether you need boost converter, guess for debug you'd have Schottky diode to USB power as well !
Please repeat all after " In this video I will show" ! Blimey this one's a bit of a shocker but a godsend for those starting out with this chip family as I plan to be....cheers.
From experience I can tell, the best way to learn is by finding a project you'd like to spend the next couple of months on, then figure out each step of the way. Look up tutorials on youtube to get an idea of what to do, ask ChatGPT for specifics, be curious and experiment. You'll learn faster by doing than reading.
This is so cool!! I'm about to design my own project and bought stm32wb instead of esp32 and then you uploaded this video, i'm so happy. 😊 Btw, do you think it would be hard to update the firnware through bluetooth when i have then connected in a mesh network?
With all the additional files that get generated after enabling BLE what is the "proper" place to write normal code (like flashing an LED)? Is it still main.c or somwhere else?
Depends on what you require. In main.c while loop, you'll see that a BLE 'task' is actually run. Some code will be in main, others like shown in the video may be in event handlers.
I want to make more analog design videos, which'll go into detail on sizing passives for those circuits. But as Jeffrey said, the mixed-signal course goes into quite a bit more detail.
would love to see it one day using all the same st libraries and codebase.... except over on the platform io plugin ide for vscode. this also includes live native hardware debugger, courtesy of stlink and microsoft.... and i believe it operates the stlink/swd or jtag connection using openocd cmdline program under the hood. to be clear: rather than st's own proprietary stlink connection software.
noice! Please make a tutorial on making a very simple usb stm32 device that is not the common USB keyboard/mouse/serial hid. A custom USB device that will be detected as Phil's USB MCU. windows driver for this Phil's USB MCU and a simple C terminal program that will take user input to send 'a' or 'b' to turn on/off a led. I have already exhausted all google search results.
This is so much better than the ESP32 platform. Had a nightmare time getting up and running on that without going the arduino route. Currently working through video #2 and will get the board fabricated soon.
Yeah, I'm not much of a fan of the Arduino environment, but still am planning on making a video covering ESP IDF. I'm just so used to the whole ST ecosystems, that - despite some bugs - it feels quite straightforward.
To be fair, arduino has its uses. No one can deny its been incredibly successful as bringing microcontroller project design to the 'masses'. Ie a general hobbyist who just wants something relatively quick and doesnt mind (or understand) the dirty. It is a tool to allow hobbyists to relatively 'easily' get into things etc... Is it 'pro' grade or a thing an embedded engineer would use during their day work? Of course not, but thats not the market. People who have embedded experience do it the way Phil does with STM tools and debuggers etc.. (for STM microcontrollers). Arduino is what arduino is.
@@Thats_Mr_Random_Person_to_you For me I had no embedded experience at all but came from other high level languages (Java,C++) and was used to fully featured IDEs. This is why when presented with the Arduino IDE I just couldn't deal with how limited everything was. Thanks to this channel I discovered STM32 and love it.

Neat! How did you find the protocol?
@@GoPaintman It's a Ford RDS 6000 CD stereo. TL;DR; I found existing projects that implemented the necessary parts of the protocol, and one of them also had scans of the original specification document.
I found a pinout for one of the rear connectors that was unused on my car. The names looked like AUX related. Simply feeding some audio signal into it did nothing. Looking further I found that CD Changers are a thing and I figured out that ACP+ and ACP- are supposed to be some data communication pins. Searching for Ford ACP lead me to a lot of existing projects, even dating back to the pre-arduino-era. I wasn't completely happy with the implementations I found, I even considered buying a CD Changer from Ebay to reverse engineer the protocol.

What's the process in choosing the chip antenna? / Reason for the AMCA31-2R450G-S1F-T3?
Looking at datasheets, this one seemed very straightforward to integrate.
it is nice🎉 it’s a great video to start this board. Could you recommend some nice tutorial for Bluetooth stacks , maybe some websites or books. Thanks 🎉🎉

I have also had a look at AN4718 which talks about VBAT and coin cell use.
Do a video on the current transmitting transducers how to read the current using micro controllers if possible:)
interesting
thos i would use a ESP32 since it also has WIFI
on a side note do u intend to make a MPU design video?
Great content Phil. Can you do a UWB pcb bring up and firmware , it will be interesting to see your approach

Btw, do you think it would be hard to update the firnware through bluetooth when i have then connected in a mesh network?
Awesome, hope all goes well with your design! There are some guides on how to do OTA DFU (e.g. AN5247), but I haven't given that a go myself yet.
Thanks so much. Excellent video-tutorial. Could you share the files of electrical diagrams and BOM/BILL of materials?. Thanks in advance
Thanks! You can check out the KiCad tutorials linked in the description, which essentially have the same schematic/BoM.
The components are soldered at home or are already soldered? What supplier are you using for pcbs? I like your projects🙂
Thanks! The board was fully manufactured and assembled by PCBWay.
Great video
Thank you!
With all the additional files that get generated after enabling BLE what is the "proper" place to write normal code (like flashing an LED)? Is it still main.c or somwhere else?
Depends on what you require. In main.c while loop, you'll see that a BLE 'task' is actually run. Some code will be in main, others like shown in the video may be in event handlers.
Can you make a video where you design a PCB and show how you calculate the capacity or resistance of a component? If you can of course! :)
you can buy his mixed signal design course. I bought it too. it's a gold mine! he will show you the full pcb design steps
I want to make more analog design videos, which'll go into detail on sizing passives for those circuits.
But as Jeffrey said, the mixed-signal course goes into quite a bit more detail.
@@PhilsLab Hi, I'm interested in Mixed signal design course but what are the prerequisites please?
Thanks 👍
Am I hallucinating or did the most recent video disappear?
would love to see it one day using all the same st libraries and codebase.... except over on the platform io plugin ide for vscode. this also includes live native hardware debugger, courtesy of stlink and microsoft.... and i believe it operates the stlink/swd or jtag connection using openocd cmdline program under the hood. to be clear: rather than st's own proprietary stlink connection software.
I've yet to try out that setup - one day hopefully, as I've heard good things about that!
noice!
Please make a tutorial on making a very simple usb stm32 device that is not the common USB keyboard/mouse/serial hid. A custom USB device that will be detected as Phil's USB MCU. windows driver for this Phil's USB MCU and a simple C terminal program that will take user input to send 'a' or 'b' to turn on/off a led. I have already exhausted all google search results.
This is so much better than the ESP32 platform. Had a nightmare time getting up and running on that without going the arduino route. Currently working through video #2 and will get the board fabricated soon.
Yeah, I'm not much of a fan of the Arduino environment, but still am planning on making a video covering ESP IDF. I'm just so used to the whole ST ecosystems, that - despite some bugs - it feels quite straightforward.
yea some call it arduino hell since getting out requires a lot of learning but IDF is ok
To be fair, arduino has its uses. No one can deny its been incredibly successful as bringing microcontroller project design to the 'masses'. Ie a general hobbyist who just wants something relatively quick and doesnt mind (or understand) the dirty.
It is a tool to allow hobbyists to relatively 'easily' get into things etc...
Is it 'pro' grade or a thing an embedded engineer would use during their day work? Of course not, but thats not the market.
People who have embedded experience do it the way Phil does with STM tools and debuggers etc.. (for STM microcontrollers).
Arduino is what arduino is.
@@Thats_Mr_Random_Person_to_you For me I had no embedded experience at all but came from other high level languages (Java,C++) and was used to fully featured IDEs. This is why when presented with the Arduino IDE I just couldn't deal with how limited everything was. Thanks to this channel I discovered STM32 and love it.
I did everything like in the video, the code uploads without any errors, but my device is not discoverable in ST BLE app. Can someone help?
same
Is it possible to run a language like c# on an microcontroller like a stm32?
Not as far as I'm aware - although there may be some dedicated compiler out there.
STM32 runs ARM Cortex processors mostly, have a look in the Mono project which aims to provide cross platform .NET functionality
Maybe next project could be related with IoT, like zigbee network
YES!!
Nice👍
Thanks!
Arduino but with nrf24
Your voice has changed. Is everything okay?
I had a cold while recording, but thanks for asking 😊
👍❤🙏
