Posted on October 26, 2015 at 09:23i m using stm32 Cube mx codes for USB OTG FS host.with most pendrives, the host channel interrupt and RX queue level interrupt is coming normally, around 20-25 times during mass storage class initialization. but wi...
Posted on October 24, 2015 at 00:13Hello, In the past couple days I was studying the communication between STM32 and PC via CDC/VCP over usb. The code seems simple and works on F4 discovery board, but it just didn\t work on my own board. After sear...
Posted on July 29, 2015 at 15:56Hi there, I have been looking for a documentation about the STM32F2XXXX Family concerning the HAL driver. I downloaded the package concerning the examples and tutorials named STM32Cube_FW_F2_V1.1.0 or so but the doc...
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...
