Which CDC-device exactly do you mean? I have Holtek HT42B534 usb-uart bridge.

I apologize for my long response. If the stm32 device has a full speed USB interface, then the RXTYPE and TXTYPE registers are incorrectly initialized in the usbh_myevice_init function. They...

You have incorrect values ​​for the USB->RXFIFOSZ and USB->TXFIFOSZ registers: 2^(6+3) = 2^9 = 512. You need to do: USB->RXFIFOSZ = 3 and USB->TXFIFOSZ = 3. Accordingly: 2^(3+3) = 2^6...

I have a very simple implementation of udelay. Change this function: void udelay (u32 us) { for(u32 tmp = ctr_us + us; ctr_us < tmp; ) {}; }

Thank you everyone for your interest in this project. Special thanks to @WebDust21 for his [response](https://github.com/minilogic/f1c_nonos/issues/5#issuecomment-2203774672) regarding getting started. Indeed, learning any new project should begin by looking at the...

[LVGL9](https://github.com/minilogic/f1c_nonos/tree/main/src/gui/lvgl9) example has been added. https://github.com/user-attachments/assets/db216dea-c39e-4bb4-ad38-d4f8491db229

In the [USBMSC HOST example](https://github.com/minilogic/f1c_nonos/tree/main/src/usbh/msc), added waiting for any key press in the terminal. At this time, you need to connect the drive through the adapter. 

@WebDust21 You're probably right and it's worth trying double buffering. It's a pity that I have so little free time. This damn war took away not only my home and...
