I use NUCLEO-F722ZE and STM32CubeIDE.When I set SDMMC1 to SD 4bits wide bus, the RCC shows a warning “partly disabled conflict with : SDMMC1 : SD 4bits wide bus”. At this time, when I wrote a program on the board and operated it, “FR_DISK_ERR” occurr...
Hi, I am using STM32F746 controller for development. So my hex file size is too more then controller flash memory. So I am trying to use Moving internal flash data to external flash Making external flash work as internal.So kindly explain how to achi...
Hi, I am working on STM32F1 family and implementing LIN communication. I found the function HAL_UARTEx_ReceiveToIdle_DMA() that is very useful to handle variable incoming data. But I have a problem that this function only works first time, but not ca...
I'm simply trying to do:res = f_open(&fil, "file.txt", FA_CREATE_ALWAYS | FA_WRITE);but nothing is created despite the return message. Could it be my SD card? I'm able to read from it in 4B mode.Any suggestions would be gratefully received.
The MCU I'm using is STM32F743H7IIT6.I am trying to perform firmware update via the USART bootloader protocol. (AN3155Application note) Everything was working fine with many .bin files until one .bin file crashed the update. When I debuged I found a...
Hey all,i need to use the Rust Programming Language. Now i want to enable the PLL to increase the system srequency.I'm using the "stm32h5" crate (https://crates.io/crates/stm32h5). let dp = stm32h563::Peripherals::take().unwrap(); // Setup handler f...
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...
