Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I have a custom bootloader in my application. This bootloader write some data in one of the sectors in the STM32H7, lets call this data "bootloader flash data".This bootloader flash data is written to/read from multiple times during DFU, and to get i...
Hi Everyone,I'm working with LL driver and want to read the system clock. There is this function:LL_RCC_GetSystemClockFreq(PCLK1_Frequency)to get the frequencies but although I include stm32f1xx_ll_rcc.h, I receive this Error'PCLK1_Frequency' undecla...
In the ST's example about the use of LPT with RTOS (STM32Cube_FW_L4_V1.15.1\Projects\B-L475E-IOT01A\Applications\FreeRTOS\FreeRTOS_LowPower_LPTIM). In the function 'vPortSuppressTicksAndSleep()', the interrupt is disabled as below:/* Enter a critica...
Hi I am very new to write a code for USB communication. I am looking for helpful link or resource in setting up USB based camera communication over ethernet. I have the following questionsWhat does the video camera acts like a USB host or Device?How ...
I have used CubeMX to generate a project with All defaults + LwIP enabled (no RTOS) and it runs well. I receive an IP address via DHCP and can ping the board. When I add the FreeRTOS with CubeMX the TCP stack is not running. No ARP, no DHCP and no Pi...
Termination of server thread and closing the connection is done in the disconnection of ethernet cable and the thread is recreated when ethernet cable is reconnected, the accepted clients run in separate threads. I am also terminating client handle t...
I am going to setup lwIP on STM32f107RCT6 and DP83848. I used CubeMX to generate primary code. After downloading the code into MCU with command ping and arp –a the result is: (MCU IP: 192.168.1.57 *** Subnet: 255.255.255.0 *** GW:192.168.1.1 *** MAC...
Hi,In our system design a usb host will be connected to STM32F205 all the time. Can we update our software via USART1 using system bootloader embedded to stm32 while this usb host is connected?In 9.2.3 Bootloader Section, it is stated that "If a USB ...
Hello!I am tryig to create my own USBPD project on P-NUCLEO-USB002, and using UM2552 manual.I add to project some files (see screenshot) and have compile error.On the page 20 there is string: "For details see the file usbpd_dpm_user.h, which contains...
When my code (STM32F303VC) starts up, it initializes the USB as a peripheral device. At this point the USB has not completed its connection with the Host. The Host still has to recognize the USB device and connect to it. If I try to communicate with...
