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...
Several years ago we started a project using an F429 main and 8 F413 slaves, communicating over an SPI bus. In 2020 we stopped the project because of too many problems with ST-provided drivers/stacks, especially Ethernet/lwip and USB, and very poor F...
Using the B-L462E cellular board with Azure NetX MQTT code to connect to, publish and subscribe topics on my own mosquitto server. How can I reconnect to MQTT after the server restarts? Code is attached. When the mosquitto server is shut down, the co...
In a current PCB design, SWD debugging is very erratic. Stepping through the code line-by-line works fine, but executing multiple lines will sometimes result in an apparent crash with a call stack like0x08061300xfffffff9which doesn't make any sense f...
HiI am stuck with STM32H743IIT I2S DMA RX ..The code is working perfect when uncommet HAL_I2S_Transmit_DMA (Line 29) but when uncomment line 31 HAL_I2S_Receive_DMA it feedback HAL_OK but do never go into the callbacks ..What can be the issue ?Best re...
There are some comments in STM HAL driver code: stm32f1xx_hal_eth.c "The PTP protocol and the DMA descriptors ring mode are not supported in this driver". Can this driver work with zpehyr RTOS and the Ethernet Rx works in interrupt mode?Also, inside ...
I am trying to create a frequency meter in a STM32U575ZI microcontroller that works with ThreadX and low power consumption using the low power timers LPTIM3 and LPTIM4, as well as an interrupt using EXTI 14. In summary, I use LPTIM4 to count input p...
I am using STM32F407 and want to use USART interface to flash MCU using bootloader. I have external 25MHz oscillator connected to the MCU.I've noticed that there is drastic difference in booting delay time I need to implement on different bootloader ...
Hello everyone,I create my firmware project in FreeRTOS environment at STM32L476 EVB, I place code in bank1 and when I execute bank 2 flash section operating like erase/program , firmware will crashed, but if without FreeRTOS condition, the same ope...
