Idk if my brain just changed to get the hang of it or you are a grat teacher - but I could follow 2 of your tutorials better than almost anything in the months before. Thanks!
Thanks for the video. I got it working too perfectly! I actually had a bit of a nightmare because I decided to use one of the GND pins instead (there's two, so I get to keep SWIM pin - great idea right? Nope!). So I cut the track to the top GND pin and soldered the wire as per the video, went to check the other GND pin to make sure it was still working...nothing! I then realised that the GND pins have a via in the middle of the pads connecting them, so in actual fact I had cut the ground to BOTH GND pins!. So I then had to remove the pin that I wanted to remain GND from the connector so that I could remove the pad it was soldered to (which was now connected to my new SWO pin!). Then insulated the via just in case, put the pin back in and ran new GND from the ground plane on that side. It worked in the end, but I should have bloody just used the SWIM pin instead! hahaha.
I am unable to debug using STM32CubeIDE. I have both a clone ST-Link V2 and genuine ST-Link V2. I can program using STM32Programmer but when trying to run or debug in STM3CubeIDE it fails on either with the message "Error in final launch sequence: Failed to start GDB server".
Check this other video! It should solve your problem! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JqrUAzjJ0tw.htmlsi=cSYUVVaLQLgeETik Thankyou for messaging!
The original plan was to make it autonomous, but for safety and control reasons, I am currently using a tether. This tether communicates with a twisted pair and powerline modulation to establish an ethernet connection with an onboard Raspberry Pi. The Raspberry Pi then sends the data to a PC on the surface. Thankyou for watching! Where you interested in me expanding on a certain topic?
Thank you!!!! I didn't know I was missing a pin for SWO. Now it works. The soldering is really difficult on a package this tiny, I couldn't solder it without making a short with one contiguous pin. I did take the risk of leaving it like that and it works, so I'll leave it.
Hi Can we change transition of screens from one colour to other colour based on sensor readings? Example: If ultrasonic sensor reading is less than threshold it should show red screen and similarly green screen. Please do let me know.
Hey, I don’t know if you still make videos but I’ll ask anyway. I’m in highschool doing a research on AUVs and wanted to make one on my own, it would be very cool and helpful if you would explain the general concept of making one in another video, thanks
Hi! Its so nice to hear from someone like you! I will make one for sure! Thankyou for the support! Whats the project exactly? Best of Luck in the mean time!
@@marcomotaelectronics3134 I started researching on AUVs not so long ago, the resources that are available for people without expert level capabilities are slim, your video outlines key problems in comms which helped alot. But the general aspect of it would be, explaining to a non-technical audience like me how to design an AUV and what goes into consideration and a basic understanding of how to program the autonomous capabilities. It would be very helpful if you did something of the sort, thanks alot.
Your variable "i" is pronounced aye you are saying e sounding like variable "e"😲 other than that your English is not bad and the video is vary intuitive, you are probably better at coding than me as well, although that does not take much. Hence why I am watching your video, Thanks!
With BlackMagic Probe (BMP) Firmware, this method is now obsolete. In addition to running locally as a remote GDB server, BMP also runs directly on STLink probe and reconfigures the RST and SWIM pin as UART RX/TX. Of course, this means you'll have to flash BMP on your STLink which is easy.
Interface level: 3.3 V (Compatible with 5V); Output signal Serial Port (UART) (TTL level 3.3V) --> i dont understand your claim it couldnt handle 5v rx tx levels; also a more in-depth explanation of the code would have been great; from my understanding there are two sources one could get the concentration from - pwm and uart but the calculated values of both arent the same in my case. Do you have similar experiences?
I suppose you already did this, but for anyone reading, don't pull to the IO pins side. Pull the metal case to the USB plug side and it will easily come out. You can help pushing down in a table with the usb plug facing down.
You get it with the board when it gets shipped. Dont know a repository that gives it to load to the board tho. So basically the board gets shipped with the demo installed into it.
Hello Marco, thanks You very much for this nice video. I would like to make a Wave table synthesizer with a Black Pill (STM32F403CCU6) and an external DAC (PCM5102A), could you please public a video of such a configuration using I2S and DMA?
Thanks for the video. Kept me from pulling my hair out. I live in California and you speak English better than most people I know. Don’t apologize for your accent. Thanks again
If you could revisit this and make an updated video on the entire installation process that would be great! I'm having a hard time with all of the packages required and errors that I just can't get around. Support for this is almost non existent.
Hi, I'm a beginner in ROS. I think it would helps a lot if you could make a tutorial from 0 (no packages on your PC, just ROS installed) to this video with launching all the simulation on Unitree and eventually trying to make an Autonomous Walk through Rviz ? (Moreover there is not a lot of information on Unitree robot)
If you connect the 3.3V and GND it already powers the board, you should see the schematic. If the board requires to much current, then it's better to only connect the gnd and for the power rely from an external power supply.
Yes, sure. I probably can make a video about high level control. Probably I will not be able to do a vdeo about low level control since I didn't have the possibility to test it practically.
