I have successfully got data going to Azure IoT hub, but now need to connect it to Azure IoT Central instead. I've not managed to get it to connect successfully though... This is the device settings, which are in the azure_iot config.h file, but I've...
I started learning about it while playing with WWDG_Example from STM32446E_EVAL.I can enable WWDG and tie it to my EXTI button on my Discovery board.The board will reset when the button is pressed and __HAL_RCC_GET_FLAG(RCC_FLAG_WWDGRST) == RESET.Wha...
I'm a bit of a novice at programming, but I'm trying to develop an application that sends a continuous stream of data out of the USART using DMA, taking advantage of the DMA Transfer Half-Complete, and Transfer-Complete interrupts. I've got a circul...
Hello, I'm using an smt32u545re in GPDMA mode. I followed the videos "STM32U5 workshop - 07 GPDMA in practice - coding and debug in STM32CubeIDE" on YouTube. I am obtaining an array of 64 values in total, 16 values for each adc channel I am reading f...
Hello team, Is there any way to format the external flash of microcontroller, the reason is that that flash is acting as USB MSC Device. As soon as it connects to PC a popup will arise for disk format. Am planning to do complete mass...
Hello, I have a problem with unaligned access, which generates a hard fault when the software is started without bootloader.When running the same software from mcuboot bootloader, there is no hard fault on unaligned access.The MPU and TrustZone confi...
Why doesn't ST provide LWIP support for H5 series. Otherwise is there any option to add any other IP stack directly configurable from StmCubeIDE?
