I have an STM32L011F4P6 with an RTC. It is running at 3.3V and 16 MHz off the internal HSI RC clock. The RTC is driven by a +/-20ppm 32.768 KHz crystal. It is running at room temperature (23-25C). After calibration, I am losing several seconds pe...
In my project I've set the SPI clock to 125MHz; with a SPI prescaler value=4 all works good, when I set it to 2 the SPI stops working and ther is no clock signal.Any helps ? Thank youCarloV
I call HAL_UART_Init() with LPUART1 at 20Mbaud but when I activate assertion it fail at IS_UART_BAUDRATE().The IS_UART_BAUDRATE() is not correct for LPUART that can have a baudrate up to 53.3 Mbaud.Also for UART, the comparaison in IS_UART_BAUDRATE()...
I’m working on an STM32H7R7 project using SDMMC1 + FreeRTOS (CMSIS-RTOS v2) + FatFs, all generated with STM32CubeMX.I’m facing an issue where f_mount(opt=0) works, but the system blocks inside f_open() and never returns, so the return value cannot be...
Greetings!I have the following system:STM32U073CCVBAT pin is connected to a super-cap, and it's voltage was measured to be above the required minimum.During system reset (NRST) it behaves according to my expectations, the RCC_BDCR remains unchanged, ...
Hello,I dug deeper into PSSI behavior, and and I observed unwanted behavior. From my point of view it is a bug.PSSI is configured as:OUTEN = 1 (transmit mode)CKPOL = 0 (outputs driven on rising edge, inputs sampled on falling edge)RDYPOL = 0 (0 at in...
Hello, We have developed an image capturing application successfully based on STM32H7xxxx and OV7725 camera. We are now targeting to port the application to target STM32U5xxxx with the same camera. But it looks the DMA doesn't works as expected. T...
Hello @Imen.D , A side question: RM0440 for G4 says oversampling mode does not support offset. Any change to this position as like the H7 change? Solved: 'H7 ADC offset correction in oversampling mode - STMicroelectronics Community Thank you. SK
Hi,how do I start the USB DFU Bootloader with a STM32C071 Nucleo? I tried it while putting Boot0 to high and pressing reset or do a power cycle but the STM32 DFU does not show up in the device manager. I connected USB to the NUCLEO extra USB port of ...
Can i use UART + DMA ( normal ) + RTO ? I try to add RTO but when activate RTOE bit the DMA buffer stops fills .I take interrupt with active RTOF , stop DMA , but nothing in buffer !? I use stm32H7 with hardware implemented RTO. Can some one to give...
