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 am working with the STM32H757 on a custom board.The M7 runs with FreeRTOS, the M4 is bare metal. Both cores have output GPIOs connecteed to LEDs which allow me to make sure that both of the cores are up and running.At the begining of the code for ...

Hi everyone,I need to run a MQTT broker on my board powered by a STM32F746. I managed to get the LwIP stack running properly as a starting point. I verified this by sending and receiving topics with the provided MQTT client implementation of LwIP.LwI...
Hi everyone,I am using X-CUBE-CELLULAR v6.0 and would like to use DMA on UART to replace the original interrupt receiving method. The original method is calling IPC_RXFIFO_writeCharacter() in HAL_UART_RxCpltCallback() and notify upper layer when an...
Hello. I have run into a problem in a MCU project I have. I'll explain the situation.We have a STM32F072RB -based product where we are implementing firmware update functionality. There would be 3 binaries in the MCU:Custom "thick" bootloader selectin...
Could you please explain to me "USB_CRS_SYNC" functionality? And, is it necessary to be used with "USB_DM" and "USB_DP" please?
As I understand from the low_level_output of ethernetif.c, I could have up to the number of ETH_TX_DESC_CNT of buffers.In the stm32h7xx_hal_eth.c ETH_Prepare_Tx_Descriptors (not counting the context descriptors) I "upload" the buffers to the Descript...
MCU is STM32F207VIT6 (client)server is windows application.LWIP library is used.Is there any ping command?
I have this code:void bootloader_jump_to_app(void){ pFunction Jump; uint32_t JumpAddress; HAL_RCC_DeInit(); HAL_DeInit(); JumpAddress = *(__IO uint32_t*)(APP_ADDRESS + 4); Jump = (pFunction)JumpAddress; __set_MSP(*(__IO uint32_t*)APP_AD...
I am having trouble getting independent stereo audio output on the STM32F469I-DISCO development board. I am passing data to the cirrus audio codec using the stm32469i_discovery_audio.h functions:BSP_AUDIO_OUT_Init(OUTPUT_DEVICE_BOTH, 80, 48);BSP_AUDI...
