STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello,I have been utilizing the OTG_HS peripheral on an STM32U5A5 to act as a USB host. I am using the USBx stack in a non-secure application and initializing the peripheral as follows: VOID USBX_APP_Host_Init(VOID) { MX_USB_HCD_Init(); ux_host...
USB_FlushTxFifoc & USB_FlushRxFifo API flag USB_OTG_GRSTCTL_TXFFLSH & USB_OTG_GRSTCTL_RXFFLSH can not clear when set.
Hi all,I'm using an STM32F413 to write to an uSD card via DMA over SDIO. I'm using the FATFS (R0.12c). Up until now, I've been writing to the SD card by firstly mounting, opening the file, write, write, write... then closing and unmounting. I'm writ...
Hi All,Probably easy question, I would like to use DMA with QSPI (e.g. HAL_QSPI_Receive_DMA) but STM32CubeIDE/MX (1.16.0) is not giving me any options to configure it.There are no options, my parameter settings are belowQSPI is working fine in Indire...
Hi in custom design arrive problem , that seems as hard to solve. TIM3 CH1 and CH2 config: TIM_TimeBaseStructInit(&timer); timer.TIM_Prescaler = 1-1; //48Mhz/1/2000=24kHz timer.TIM_Period = 2000-1; timer.TIM_ClockDivision = 0; timer....
Hi everyone, I am trying to use LPTIM1 and I2C3 to read the values of a sensor's register every 1 second and save them into a data buffer while in Stop2 mode. What I would like to know is if it is possible to store data sampled at a given frequency ...
My project uses multiple different GPIO's configured as EXTI interrupt sources, and there is a point where, after calling the API:HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFE)Some different instructions should be executed depending on which EXTI rising...
I've been working on an STM32L072 based project involving USB and USART4. I ran into an issue that puzzled me, so I figured I'd post about it here to help others. If there is a solution to this problem, even better!My original design used USART4 as a...
Hi,The datasheet DS13311 rev. 5 defines the max. SPI clock for the OCTOSPI only for VOS0, what is the max. SPI clock for other Power Scale settings (I'm planing to use VOS1)?best regardsmartin
I have got 3 identical boards with STM32u5a5. For improving ADC accuracy I want to calibrate Vref using Vrefint. This is working fine on one board, but on the other two boards Vrefint reads as 0 using the same software. Other ADC channels seem to wor...
