Posted on July 14, 2015 at 06:16When creating USB CDC code for devices with a USB FS port, 448 bytes are wasted. The USBD_CDC_HandleTypeDef structure in usbd_cdc.h uses CDC_DATA_HS_MAX_PACKET_SIZE to create data buffer. This is defined as 512 bytes(...
Posted on July 13, 2015 at 00:24tl;dr version: ST, please add back the xxx_StructInit() functions as they existed in the Standard Peripheral Library. Systematic use of these functions avoided many subtle bugs due to unitialized struct fields.Back wi...

Posted on July 08, 2015 at 16:55Hi folks,I'm reading up on the usage of the USB DFU bootloader capabilities for an STM32F429. It appears that the device on the other end must support the USB DFU protocol. Is it possible to configure a flash drive (U...
Posted on July 08, 2015 at 16:04Hi,I'm running a stm32f427 on a custom board as Host, HS core, FS mode. When a device is attached I get an interrupt when the device is detected and the host starts sending SOF's. But the last bits in the SOF packet i...
Posted on July 01, 2015 at 12:01 I use a custom STM32F407 board. I want to detect USB FS cable presence (no matter to pc or charger). Here is what I did. First, the VBUS pin is initialized in usb_bsp.c USB_OTG_BSP_Init function, I di...
