Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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'm trying to use DMA in circular mode to modify the duty cycle of a PWM output. Ultimately, I plan to use it to communicate with WS2812B chips (like others have done with the STM32F4 chips). However, in my early tests I've noticed that it seems to s...
Has anyone added FreeRTOS to the discovery node iot kit?I've ported freertos several times before (and have donei t on the Nucleo f411) without issue...but it is getting hung up as I try to get it set up with the discovery kit.I am setting the sys ti...
The below code cannot be reordered due to volatile storage type:void HAL_FDCAN_IRQHandler(FDCAN_HandleTypeDef *hfdcan) { uint32_t TxEventFifoITs; uint32_t RxFifo0ITs; uint32_t RxFifo1ITs; uint32_t Errors; uint32_t ErrorStatusITs; uint32_t...
I am trying to use the SPI bootloader on a Nucleo F446ZE board and have problems when issuing commands. The symptom is that every other command is not acknowledge and every other works fine. Trying for instance the GET_VERSION command gives the follo...
Im my system based on STM32H753 I would like to use system bootloader by USART1.After struggling with my PCB without getting bootloader working then I switched to NUCLEO-H743ZI2 board.From AN2606 I know that PA10 is RX input and PA9 is TX output so I...
Hi there,i am working on a composite device with STM32F4 and i got it working.I get in the device manager a MSC device and a serial com port. The issue now is i can't open the com port with any terminal program it doesn't respond.Anyone have experien...
https://community.st.com/s/question/0D50X00009XkgpsSAB/fatfs-sdio-dma-write-speedI'm trying to write WAV files to SD card on my STM32F7 Discovery board and I've finally gotten round to setting up a DMA + FATFS + SDMMC. My sampling rate is around 1Ms...
I'm using "STM32L452CC". PA11 pin in connected to battery level checking part. But I can check only ADC1_EXTI11, and I'm using ADC1_IN5,6,7,8,9(PA0,1,2,3,4 pins) DMA_cirgular.So, for battery level checking, I wanna use "GPIO_Analog". But i cannot sea...
