Hello, we are using an STM32F7 and are saving image data to USB, using mostly the BSP code (disk_write in usbh_diskio.c -> USBH_MSC_Write in usbh_msc.c and so on). However we have found it's quite slow, 6-7 seconds to save one 400x400 image. I've s...
Hi,I am having a problem using Read Out Protection on the STM32F405VE processorMy firmware has a proprietary bootloader which is stored at 0x8000000. It basically checks to see if a USB OTG lead is plugged in and if so attempts to access a mass stora...
Thank you for the new "Combined PWM Mode" for the main timers... . This really was missing in STM32F4, creating 2-3 phase shifted PWM signals with just one timer... . This is now VERY nice with STM32H7.But the discription in RM (July 18) 37.3.13 is s...
Hi,I am using STM32L031K6 MCU and SW4STM32 IDE for development. I want to read/write specific register value of i2c slave device from MCU(i2c master)Below is a code I am using.#include "main.h" #define I2C_ADDRESS 0x3c #define MASTER_BOARD #...
Hi all,I am using the Nucleo-L476RG dev board and am using it as a USB Host to communicate with a custom vendor device which has 4 interrupt IN endpoints and 4 interrupt OUT endpoints.My code has been generated using CubeMX and I have generated a cus...
Dear Imen,Thanks for your replay.I modified my project file using your new library file(ethernetif.c)And I was testing during two days.But, It has a problem yet.Previously, there was stop the ethernet in minutes.But, there was stop the ethernet in ho...
We have a customised PCB and would like to have the feature of being able to flash the firmware using USB. So, we have the USB DM and DP pins wired to PA11 and PA12 pins (of STM32L152), respectively. We also configured the BOOT0 to HIGH and BOOT1 to ...
hi I want to transfer 256 bytes from host to stm32 device over Custom HID interfaceFollowing is the report desc in my stm32,/** Usb HID report descriptor. */__ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE] __ALI...
I am using two STM32F4 controllers and communicating both of them. For code updation iam doing it through USB almost all controllers are detecting when we connect to USB but some controllers are detecting only when there is an internet connection to ...
