Use STM32 as a KEYBOARD || F103C8 || USB Device HID

[@botak333]

Hi bro, how to use this HID for control game?? I want to used for DIY steering wheel

[@TuanNguyen-pd5yo]

You did a perfect tutorial, I finish my project by follow your guide, thank you very much! Love from Vietnam

[@tanuttreratanakulwong823]

Thanks for a wonderful tutorial. Very concise and easy to understand.

[@zz3709]

@~3:07: Wouldn't you need to change the HID_EPIN_SIZE (from 4) to 8? ...since the keyboard report struct is 8 bytes?

[@Nicolas__08]

Hello Sir, Thank you for this excellent video. But I still need your help a bit. I have a problem when I connect the card to the PC. I get the message Unknown USB device(Device Descriptor Request Failed) . What should I do to solve this problem?

[@ranger81de]

Thank you very much, really great tutorials and nice website with code samples and snippets. Greatly appreciated!

[@Broman3100]

Very helpful video, and very helpful channel, it seems wherever I'm stuck on something I can find it here :)

1- How to press multimedia keys? 2- Some keys are not working like 0x67 (Keypad =) and multimedia keys? Great work. 👍👍

[@m1geo]

Did you solve this? I wanted to make an STM32 that would next/previous track, and control volume?

[@Jack-pi8ur]

Thanks, this works on my nucleo F401RE board. As nucleo board has no USB port for USB device , I have to connect USB D-(DM) to PA11 and D+(DP) to PA12 .

[@kagekiyo7772]

Now it works as keybord thanks to this video.

[@sezerkaya3573]

thanks for video but ı have a problem with keyboard hid. ı did remote control with stm32 transceiver nrf24. my problems that receiver true receiving incoming data but too much text. problems that

can you to do a joystick hid usb for pc? thank you!!

[@undefined365]

Just wants to know can I make full size keyboard by this chip?

[@breno-p2g]

mine doesn't show up the options on the usbd_hid

[@andresfelipe6085]

amazing, thank you for all of your greatest videos

[@meghakajave9463]

I found issue with this code is that even I restricted to send key data for 10 times in while loop,it continues sending keydata indefinitely.

[@v24blog46]

how to receiver data this project thanks.

This video is informative, Thank you . i have one question how can i make stm32l432 microcontroller that support the matrix keyboard (3*4) and sends information read from keyboard to the computer? can you guide and help me

[@deadall127]

awesome, everything is very clear, thanks a lot 👍

[@malkin_laboratory4692]

Great video, everything works! I've made joystick for Dendy simulator. I also use usblc6 for usb protection

[@abulqosimmuhiddinov7204]

I have a problem :). change HID_MOUSE_ReportDesc to Descriptor but I can't use; because Windows 10 STM32 Human Interface driver error!

Try with another usb.. or keep trying by unplug and plug back..

Hallo great video, do you know if it possaible to use the USB device HID for mouse inputs and keyboard inputs at the same time?

[@unomasenelmar]

Powerfull tools. Please teach USB OTG camera in mode host attach in stm32 thanks

[@noweare1]

Very useful. I put it on my to-do list.

[@iliazark1]

Letters worked fine for me... But the media keys don't (volume up/dpwn, next/previous track etc.)... With a little research I found that I need to include this functionality to the device descriptor, but everything I've tried so far (either making my own or finding online a premade descriptor), either does not work or leads to a "driver error" on the host machine... Could you make a video on how to make your own descriptor and implement it in a simple project like the one in this video?

[@a.a.patrick]

Really simplified. Thanks. Will this also work for GUI and STM32? If no, How can I interface the STM32 USB to custom GUI to control maybe d.c?

[@moazabdeljalil]

Is it possible to make it as a Gamepad?

[@lukaszM46]

does it matter if i use F103C8T6 or F103C6T6? will the programming steps be the same?

[@utsavsuha]

Hello , my code is not running as yours, the key is getting typed continuously without any delay. Can you please guide?

[@Hobarubi]

Please check "define HID_EPIN_SIZE 0x04" in usbd_hid.h It has to be at least more than 8. I set it to 0x40 (64) which worked fine for me. Before the change I had the same behaviour as you described.

[@alibarakat1056]

can you link a joystick hid descriptor? or a link for it ? also if mouse in the FS array is 0x02 and keyboard is 0x01, what is the hex number related to joystick ? thanks

[@ControllersTech]

here you go controllerstech.com/wp-content/uploads/2020/09/joystk.h I think you need to use custom HID for joystick.

[@deadall127]

any hint about how to get the led indicator status?

[@ControllersTech]

Led indicator for ?

[@deadall127]

@@ControllersTech in the keyboard hid, you know the caps lock, num lock and scroll lock. if I'm not mistaken it's an out endpoint that we need to listen to, but I'm not sure how to do that (or even if it's doable) with that usbd library. I managed to send keystrokes with my stm32f072 tho, it's amazing ^^

[@ControllersTech]

Well i don't know about it but you can check out that pdf, if any combination gives you the caps lock and all

[@jetraid]

Awesome as ever, I learn a lot with your videos. Theres a way to make a multiple HID descriptor, Windows have 32 buttons joystick limitation and y need more than that, could be posible with 1 STM shown as 2 or more joysticks?

[@68HC060]

I think the way you could do this, is to open more endpoints. For instance, one microcontroller using one USB connection may show up as a HID device on one set of endpoints, while the same microcontroller on the same USB connection may show up as a storage device on another set of endpoints. You should be able to make several sets of endpoints, so you should be able to have several joysticks. Please don't ask me how to do this, because I've never done it myself; I've only seen such things implemented by others. Note: ST-Link v2 and later show up as storage device while it's also a 'programming adapter' that works with for instance OpenOCD - some programming adapters work both as programming adapters and USB-to-UART adapters.

[@arjun64461]

hi, not sure if you're still answering but would this work for a F401RE board? i followed your tutorial exactly, except for some small differences in the initial clock setup. however, when i flashed the code to the board, it does not seem to get recognized as a usb device, nor does it print anything to the computer. any insight on the matter? thanks!

[@ControllersTech]

All the USB related videos needs user USB port. The nucleo f401 comes with 1 USB port by default and that's for the ST link. If you want to use the USB, you need to solder a new port to your board. You can see towards the bottom, there is space given to connect it.

make an array for the keyboard values uint8_t keyboardHid[8] = {0,0,0,0,0,0,0,0}; and update the values just like i did in the structure, but use keyboardHID[0], or [1], or [2] for the modifier, reserved, keycode1, etc
