Posted on October 16, 2015 at 14:17Hello, I have a bootloader communicating over USB and the application which is loaded and started uses the same USB port. When I use the bootloader and start the application the USB port isn't working inside the ap...
Posted on October 21, 2015 at 12:44Hi, All, I downloaded STM32CUBEF4.zip from the official website. (STM32Cube_FW_F4_V1.9.0) I am exploring the driver dependency when I found the following problem. I am using STM32F411RE-Nucleo, by the way. Why in s...
Posted on October 16, 2015 at 04:08I have been trying STM32Cube software on STM32F072C8T6, specifically on the USB middleware.My program is as simple as declare an OUT BULK endpoint. I'm toying around the idea of double buffering.So in USBD_LL_Init ...
Posted on October 16, 2015 at 19:24 I worked a lot with the StandardPeriphLib but now I try to migrate over to the HAL driver for new projects. The HAL driver come with a heavy overhead. For example, without any optimization level the function H...
Posted on August 06, 2015 at 16:46In the STM32F0 reference manual it states that only the STM32F070x6 and STM32F030xC devices support the empty check for entering the bootloader on virgin devices. Is any way to enter the bootloader on the STM32F030C...
Posted on October 16, 2015 at 11:37We are using STM32L053 in our project. We evaluated the USB data transfer using CDC(Virtual COM port) and USB composite device. However, both of them require specific ST drivers for the PC to recognize the USB devi...
Posted on February 23, 2014 at 17:22 Hi Guys, I would like understand the procedure that the USB CDC does when it is going to receive data over the USB interface ( If you can explain me, would be great). I could see thatVCP_DataT...
Posted on October 16, 2015 at 13:39Hi all I've been using the STM32F429 discovery board since a long time with optimal resultsI've been using USB HID device profile successfully for long time.Now I'm trying to put CPU in low power mode (the first ty...
Posted on October 16, 2015 at 12:20Dear all, I'm using STM32F4 Discovery board and I wrote two separate projects: Audio USB Device (that uses Audio class USB descriptor)General purpose Device (that uses CDC USB descriptor)How can I merge these tw...
Posted on October 13, 2015 at 15:15Hi, I'm using STM32f407 for a USB project. I use CDC class (STM32_USB_Device_Library) for implementing USB device on my OLIMEX EVAL board. When I connect my board to PC, it appear as VCP, as shown in the figure att...
