I have a general question. I am using STM32F423 and STM32L407 Evaluation boards for practicing. So in both there boards they are using the debugger IC which is STM32F103CBT6.i. Why are they using this IC and what exactly does this IC does in program...
Posted on May 10, 2018 at 14:30I'm developing an HID USB Host application. I have already opened a discussion (https://community.st.com/0D50X00009XkX0ASAV) about HID USB Host and I applied all the suggested patches in forum, but now I have another p...
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....
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...
