This is just going off my head at the moment. but have you reset the interrupt bit. So interrupts have a higher priority over the main loop. If you don't clear that bit in the NVIC it will loop in that interrupt because it has the highest priority.

@brendenadamczak9283 👋 thanks for the reply...I just figured out after couple of days...in STM32 we use USB_LL_Trasmit function....which will send the particular data at particular endpoints. For eg if ox82 then it's Interrupt IN endpoint for the host...so the host will always take this data as Interrupt and can be resolved on priority basis as well

oh, actually are you using VBUS as the 5V output for host usb? thanks!

@@augustusallan3619 Exactly! The pico is not 5v, but the power into the pico is.

do you know how to program?

Well i can deficiently send you some just general pebble steel boards if you want. Since i won't be using the internals. But do you right software at all. The boards in the images are fairly fresh. So they won't do much without a good amount of software for them.

Because i was new to making youtube video's. When i made the video i was on a 27 inch screen monitor at full screen. So to me at that size it looked fine. haha

Your camera uses bulk? Camera's should use iscronous because it forces a certain amount of bandwidth from the host.

@@brendenadamczak9283 yes actually you are right. Previously all camera uses isocronous but now a day I see some of the cameras uses bulk. For example cisco room kit device is having hub with audio, camera and network hdmi so here camera uses bulk endpoint. Can you pls explain how host sets bandwidth , is it depends on camera endpoints ? Or packet size ? Can you do one video about how host sets bandwidth or how can we debug bandwidth related issues like video lagging or video chopping. Thank you in advance

@@lifeonagriculture3330 O BOY, that does sound interesting! But at the moment I don't have a good way of knowing this information, but it would be really helpful to know! So i'll see what i can figure out. As for bandwidth expectations. There are calls in the UAV camera spec. But i don't know how that relates to the rest of the USB spec.

​@@brendenadamczak9283 Thank you

Is any doc or video about buffer management of queueing and dequeueing , Actually jn project allocate 2 to 4 buffers to copy data and dequeue it but I am not sure what is the size of buffer and how only these 2 or 4 buffers mange speed data comes from device and gives GUI. Thank you in advance

I don't know what you mean by "Left over capture data". What are you trying to capture?

​@@brendenadamczak9283 At 3:43 you can see the "left over capture data" row is selected. I am not getting that, instead the packets have "HID data" so how can I fix this?

I would love this! I read hackaday everday. haha

Maby when I make prototype 2. I might try this. Currently I just got my prototype for the board that goes in the watch! So, there's still a long way to go, but it's coming along. ruclips.net/user/shortsl-dQ7Yjkrbk

I could make a hackaday project page. Maby thats the next step....

Thanks! What project are you more interested in and are you a software/hardware developer. :) haha

i don't see why not

@@brendenadamczak9283 would make an awesome gamepad option for dos games that are limited to 4 buttons, those games can use more inputs from a keyboard than a pad like the gravis gamepad. I have a device like those that is using Arduino, it has a PS/2 keyboard passthrough and using the keyboards scroll lock key you can manually map keys to gamepad buttons. It works really well but I don't think the creator of my device is still making them. Using a pico board would be a nice cheaper, hopefully open source option.

Good question. but I don't know. Don't really use micropython really.

Part of it ya. The OS is run in C and you make apps in Javascript.

So it sounds like you want to take in a usb keyboard and then spit out usb keyboard data as well. If that's the case you can look at this video. ruclips.net/video/iOD-NOzgj7o/видео.html

Ya i'm very happy about the visuals, but ya the audio's fairly bad. I've remember the audio was very bad, but i just stuck with it because i didn't have it in me to record it again. Also i remember i was hell bent on using all open source software and it can be ruff. I found the best way was to make the video then export the audio to audacity to do the mix and the rerender the video! Lately I'm too lazy and have no time so i just use imovie. But since this video i've bought a real mic and not the mic i used to do concerts with.

After some long hours researching on the WWW "world wide web" for the origins of what you were trying to describe here. I feel like it is my role to ask you the question of "what a ligma fork is". Therefor I will do the honors of asking this. What is a quote "ligma fork" unquote? Also, who is this person who makes recipes? I imagine this person to be extremely cool because of all his ligma forks collection.

@@brendenadamczak9283 he is a youtuber called futureCanoe he makes cooking vids lol

Very interesting. So what do you plan to do with this information? Also note that a semi complicated device like the jabra headsets going to have multiple types of usb descriptions. One for audio and probably one for HID to control muting the audio and stuff like that.

Well in the main loop you can look for a given pin and toggle it high. If its helpful i have a simpler version of this, which is just a keyboard input. ruclips.net/video/yIXa-6DRW-Y/видео.html

Seems like the only valid reason to be on windows to me. haha

Since then, I've moved on to a mini pc running Linux

You can probably make a rule with udev on Linux

I don't think you could do all of this. So you want to add a SD card like configuration file?

true :)

You'll be able to get Rs232 data from usb over wireshark. If you want to see it from a packet label

Thanks you sir​@@brendenadamczak9283

Thats a interesting question! I've never tried to connect multiple keyboards before? I've connected a mouse and a keyboard before and thats fine. You just need to specify how many Descriptions are needed in the configuration file.

Yes in theory. Once it's actually merged into the main repo i plan to do a video on it! But for some reason its not getting merged in. github.com/hathach/tinyusb/pull/1627

So if you want it now you can look at this project. github.com/rppicomidi/usb_midi_host

@@brendenadamczak9283 Thank you I'll wait for the video. C/C++ method is too complicated for me=) I might try arduino method but it's been a while since I did arduino. You think it's possible with micropython or CircuitPython?

@@UmutErhan Since the midi driver isn't in yet. You won't be able to do it in any of the way. At least i think that would be the case.

I've never done it. But the first step would be to set the flag for vender specific. github.com/hathach/tinyusb/blob/master/examples/host/hid_controller/src/tusb_config.h#L108

It should look like a much simpler version of the keyboard host example. ruclips.net/video/yIXa-6DRW-Y/видео.html. Here are the calls github.com/hathach/tinyusb/blob/master/src/class/vendor/vendor_host.h

Just to make sure what are you trying to interface too? Are you sure its a vender specific device?

I'm sorry i don't think i know how to help you? I'm not entirely sure where the problem fault lies either?

Got you covered here too! ruclips.net/video/ATGZD2AyFkc/видео.html

@@brendenadamczak9283 You Star! :)

I made a video on usb ruclips.net/video/fEDp9053eZs/видео.html. also this is the first one you should probably watch. ruclips.net/video/yIXa-6DRW-Y/видео.html

So if you look inside "Pico-usb-pio" do you see anything? If not do this "git submodule init" then "git submodule update". Then you should see files in there. Hopefully it builds after that. If that was your problem thats my bad and i updated the docs. If not just message me and i'll try again :)

@@brendenadamczak9283 [driver] Build completed: 00:01:30.302 [build] Build finished with exit code 0 done , instead of using cmd , i downloaded code form git as zip and tried to compile thanks

Probably? So the pico has a wifi board if that makes it easier for you? Then you potentially wouldn't need this PCB board? But to the original question yes. From you pcb you can talk to the pico over the same cable that powers it. You'll want to use the CMC class, which is basically a uart stream of data.

@@brendenadamczak9283 actually i'm using a device stm32 as USB CDC it's the same ?

@@mealshake4284 So this is how it sounds to me [STM32 PCB ] (USB Host) -> (USB Client)[Pico](WIFI) -> (WIFI) [PC]

If thats the case it should work no problem. The pico is just acting as a relay at that pont. Put a little ZMQ server on the pico and your all set to talk to your pc

@@brendenadamczak9283 exactly, my stm32 works as a device

fairly simple and cheap. So go for it. If you do post your results. I would love to see others doing it probably way better then me

I'm glad you liked it so much. As for the view count, I don't have any cats or funny faces in my thumbnail. So that's why it's so low 😂
