Too bad the ESP32 doesn’t support Thread

Hi, i did a lowpower video on the STM32U0. Take a look a it ua-cam.com/video/-L9rTAFgr08/v-deo.html /PR TechTalk

Great to hear!

I really appreciate your feedback! The music is "Chasing Dreams" by The Soundscapes. I'm glad you enjoyed the explanation!

I'm glad you found the video helpful! Cloning projects can be a breeze with the right steps, and I'm happy to have shared them with you.

Hi, when i get these issues i hook up an logic analyzer to the SPI bus to see what is transmitted and returned. Look for Saleae and software Sigrok. You can also try to use another SD Card preferably 32GB or less. Good luck /PrTechTalk

Hi, i have made a video on how to add SD card to any STM32MCU using SPI interface. I realise that this STM32H5 have also SDIO interface that is a much better interface. But i have not yet made any video on this. I would guess that if i do then it will be using Thredx RTOS and FileX to access this features. /PR TechTalk

Hi Jaaxc, Sorry but i have sofar done Zero work with C++. Perhaps i will need to look into this in the future. /PR TechTalk

@ i think it’s not possible anyway after googling, apparently it is quite manual to setup

You are welcome 🤗 /PR TechTalk

Hi, this is the first time i have heard something regarding this topic. But if C /C++ is not preferred what are pushed instead?

@@prtechtalk416 RUST ! but honestly it seems to me that the regulators will caught the manufacturers off guard.

@@prtechtalk416 Don't worry about it, it's just the Rust people trying force their language. If anything, there will be a push instead to force embedded programmers into newer standards of C++ instead of Rust.

Thanks

Thanks

Hi , i am not working for ST so i cant help with loging in to their site. What is the issue you are facing?

@prtechtalk416 I have downloaded stmcubeide but while creating project it is saying that packages are missing. when I tried to download packages connection time out showing so how to download and installed packages offline mode?

It sounds like you have some undefined issues with communicating with ST, I suggest you create a support ticket with ST to get is sorted och just create a new login to see if this helps. /PR TechTalk

Hi, for sure you can. I have even thought of doing a "DataLogger" for in my example see discharge curve on LiOn cells. I would then use a RTC to keep track of time and sample at some defined interval and save to SD card and then later bring that data into Excel for analyze. So hit the Hit Subscribr and the Bell so you get notifyed on new videos i release. /PR Tech Talk

Hi, This tool is MCU agnostic on some of the functions. the MCU current measurement is one of them. So yes you can use this Tool with ESP32 so measure the current consumption. /PR TechTalk

Thanks :-) /PR TechTalk

Hi, thanks for your comment! As I mentioned in the video, I'm not entirely sure it's always necessary. I agree that pull-ups will consume some current. However, the output is configured as push-pull, using transistors in a totem-pole arrangement. To prevent shoot-through (when both transistors are on at the same time), a small dead time is introduced where both transistors are off. During this brief moment, the output can enter a high-impedance (tristate) condition. Although this period is typically very short and may not cause issues in most cases, adding an external pull-up can prevent the output from floating. I've seen a few cases where adding pull-ups helped resolve SPI-SD card communication problems. Pls make some experiment and see if it makes any difference. /PR TechTalk

Thanks, Yes you can se register's in the VSC when debugging PR TechTalk

Thanks for your suggestion. Not in the plans right now but if i get more request for it then i just might :-) /PR TechTalk

Hi, Some claims that VSC are faster than STM32CubeIDE if this is true i cant say. But VSC have a lot of plugins and a great user base. Test it and let me know what your thoughts are. /PR TechTalk

My pleasure

Thanks for the idea!

@@prtechtalk416 another idea.. a tutorial of touchGFX with Azure Rtos. best reguards!

I have done some on Threadx if i am not misstaken ? / PR TechTalk

The Serial interface on HX711 is slow so i would implement a timer to not block the MCU with delay functions. And poll the data signal after the clock flank perhaps also with a small delay between flank and poll. i would use timer int and in the callbackfunction set flags that you use in your code. This migth be one way but i am certain that "real" SW hackers have alternative and better soloutions. /PR TechTalk

@@prtechtalk416 thank you for your response! you are right, the problem is that i don't want to block the MCU during the reading of the value and i would use the azure RTOS.. maybe i can use a timer interrupt and then use a semaphore to trigger in a thread the reading. maybe i can read the data on the driving low of the clock pin (i have to control that on the datasheet). thank you for your suggestion!

Your Welcome

I'm glad you found it useful! Your support means a lot to me!

@@prtechtalk416 your tutorials make my work easier, thank you!

Awesome! So happy it helped you out! Thanks for checking it out! 😊

You're very welcome! I'm glad you enjoyed it!

Hi Did you format the card with FAT ? /PR TechTalk

@@prtechtalk416 I solved. Since Stm32CubeIDE has not FatFS in Middleware for my board I add it manually and I forgot to init FatFS in main. Thank you.

Awesome job figuring that out! It's always satisfying to troubleshoot and come up with a solution. Keep up the great work!

The problem could be to find a good refvoltage at lower voltage. Your result are hevily dependent on the Ref. /PR TechTalk

If you turn of the MCU then all clocks stop and also the time keeping. You can "only" put is in some lowpowermode that still remain RTC functionality and you find this info in the MCU manual. /PR TEchTalk

Hi, You are correct in your comment that in 11:58 i define pi to a value that is not correct. This error have already been notified by annother viewer Codures. Thanks anyway to point it out. Brgds /PR TechTalk

Hi Rudolf, sorry to hear that you are having issues. But it is hard to say what might be the issue in your case. To answer this one have to review the code and that is something i dont have bandwidht to do. If you need support you can get support on fiverr.com PR TechTalk

Which chip? If G431 - then you must set "Word" size for peripheral in the DMA page. Spent a couple of days for this. Exactly same setup as in the video didn't start at G431

Hi, i don’t in understand your comment could you give some explanation?

@@prtechtalk416 It's a joke. Only Ukrainians will understand.

Thanks

Their is no advantage of that. Using 32bit variable to store a 12 bit value then remaining bits are wasted. So to conserve memory its better to declare halfword instead. /PR Tech talk

Thanks, Greate to hear that you found it helpful
