STM32 USB OTG FS CDC. CMSIS only, no HAL, no SPL. Virtual COM-port via USB OTG. STM32

[@alexsv1834]

I was surprised that this implementation works without ST Virtual Com port drivers (Windows 10x64) unlike HAL example. This works fine without driver installation.

Наконец-то! Я так долго ждал это видео.

Отлично! Долй HAL. Понятный рязанский акцент без американизмов легко воспринимается на слух. Кусок перекачки файла стоит обрезать процентов на 90.

Спасибо вам большое, поменял размер конечных точек и поехало.

Без дескриптора 300 строк и всё

nice video thank you you are right cube mx is a real gaz factory lol....

[@LiliaTroudi]

Hi! Have you tried it with the F407 that you've mentioned? I am having some issues with implementing it. Thank you for the video

[@alexsv1834]

Hi! I haven't been using 407 for a long time and I have forgotten a lot. But I tried this USB implementation just as simple as "copy-paste" for 407. If you have any issues concerning USB CDC in CMSIS project for 407 go ahead and ask me. Maybe you need a working template? I can give you one for STM32F407VET6 devboard.

@@alexsv1834 Thank you for replying! I copy pasted (I only changed the gpio configuration as the registers and pins are not the same) but the laptop is not recognizing the device. I would be grateful if you send me a working template.

@@LiliaTroudi github.com/SvetlAl/STM32_FS_USB_CDC_device_CMSIS/tree/master/STM32F407_sloppy_example that's it. Made sloppy just to make sure, that this works. The IDE is Keil. Maybe you've missed something in RCC or CP or Vector Table. This example is working 100%. If it doesn't work for you, send you debug screenshot [e-mail]

@@alexsv1834 Thank you so much! you're saving me! I will email you in case it didn't work. Spasibo!

Hi!This is me again! I have a question please, have you ever made a composite device using stm32 please? Thank you

[@alexsv1834]

Hi! Unfortunately I have no practical experience in composite devices

[@Korbomen]

у меня отправлет 1000 байт и зависает( тоже сам писал на регистрах. Смотрю ваш код и разбираюсь что у меня не так

[@alexsv1834]

У ST есть серьёзная недоделка, связанная c выделением размера Endpoint-ов. И это нигде не документировано. Шаг влево-шаг вправо, и работать не будет. Начните с этого.
