As title says.If so, where could I find an example.If not, will it be supported?

STM32H743Z - LWIP udp example without FREERTOS of the latest CubMX - 6.12.0

Hi,I'm looking for a working LWIP UDP example without FREERTOS pls.I have such a project which is working, but it was generated on old cubeMX (6.5.0) and now no matter what I did (I did some research online and tried most of your guides) I didn't man...

Resolved! Why does the value of the variable inside the interrupt not change?

In this code, the value of the range variable in the purse does not change correctly. What is the reason?Board = NUCLEO-F413ZH/* External variables --------------------------------------------------------*/ extern UART_HandleTypeDef huart4; extern vo...

STM32F765 Ethernet Migration STM32Cube_FW_F7_V1.17.2

I am migrating from Cube_FW_F7_1.16.0 to STM32Cube _FW_F7 V1.17.2 But now Ethernet doesn't work. I made changes to the file: STM32F765VITX_FLASH.ld /* Highest address of the user mode stack */ _estack = 0x20080000; /* end of RAM */ MEMORY {...

Resolved! Where to read length of sleep time on RTC WUT

We are using the STM32L071RB, currently have the firmware set to go to sleep (stop mode) and wake up after ~5 minutes with the RTC WUT (see section 22.4.6 and A13.3 in RM0377). This works great, however this timer isn't the only wakeup source. If the...

Collecting data from temperature sensor (I2C) and storing it in SRAM with less power consumption

I'm using STM32U073MCT6 MCU. I have a custom board (which contains this MCU and other required components) and I have 4 stages in my data logger that I want to develop using this board:1) Just the battery is soldered and trip isn't started2) Trip sta...

STM32H743 Flash bank swap leads to WWDG reset

Hello, I am trying to perform a flash bank swap from bank1 to bank2. Executing the following code: FLASH_OBProgramInitTypeDef OBInit; /* Unlock tha User Flash area */ HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); /* Get the Dual boot configura...

STM32F0 & G0 I2C M24C02 Emulation with Strange Behavior

Hi,I'm emulating M24C02 protocol with STM32F030 & STM32G030. To read M24C02, address is written following by repeated start then data read. Here is my code: ----main.c ----uint8_t i2c_bytes[256] ={0x55, 0xaa, 0xff, 0x00}; //Virtual M24C02 ContentLL_I...

Why would FLASH_FLAG_PGPERR and FLASH_FLAG_PGSERR be set after a successful flash write, and at power-up before any flash write operations?

I've written a flash-based bootloader for the STM32F4 using the latest STM32CubeMX tool and its HAL libraries. I've avoided all the usual pitfalls (it's not my first bootloader), and my code works reliably. I'm not erasing my bootloader segment, writ...

Resolved! LWIP STM32F7 UDP Rx Callback Data is not equal to Data Length

Hello together, I'm using a STM32F769-DISCO Board with STM Cube IDE.LWIP is activated.No DHCP, static IP.Most of the LWIP is default only disabled the DHCP and TCP parts.First, sending UDP packages is working fine. My Issue is:that the receiving udp ...
