How can I identify which STM32F0x0 parts have two or more general purpose timers?
I need two quadrature encoder input pairs. The standard ST selection matrix only includes the number of 16-bit and 32-bit timers.

USART_SendBreak not available on STM32F373
Hi,I have to configure a STM32F373 as a LIN Master. The problem is that the function USART_SendBreak is not available.The reference manual says that I have to set the SBKRQ bit to send the break frame, but this bit is only available for a break reque...
OSPI readonly in memory mapped mode
I use the STM32L4R9I-EVAL Board and try to configure the ospi on nor-flash for readonly in memory mapped mode. there is an example projekt in Hal-Lib L4 V1.14.0. If i skip the erase and write steps, it read out wrong values (with out hal error)!Do an...
STM32F7 SDMMC ignores eMMC's response to READ_SINGLE_BLOCK
MCU: STM32F777Cube: 4.25.0FW: v1.11.0I'm seeing cases where the F7's SDMMC isn't setting any of the required Status Register bits as the result ofan R1 response to a READ_SINGLE_BLOCK command after having previously handled up to tens of thousands of...
SPI interface between STM32L151QD and External Flash
Hi AllCan anyone suggest the example code for Spi interfacing between STM32L151QD and External flash memory.,Through my STM32L151QD I want to read and write from External flash memory , The both STM32 and Flash memory is connected with SPI interface
DMA can`t work in stm32h7
I saw the web https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devices,and I change the ram address.uart can transmit with DMA but can`t receive.and the spi can`t transmit with dma.
On-Top Board which fit on the Connectors CN1 ... CN2 of the STM3240G-EVAL
Hello everybody!A short questen: I crashed the uC on the STM3240G_EVAL,so is there a On-Top Board what fit on the Connectors CN1 ... CN2 ?.. Also a board to switch fast the microcontroller ..I searched for it, but didn't find such a board.Thanks, Dir...
STM32 double buffer + ADC + FATFS necessary?
Hey everyone,In my last application I had a DMA double buffer moving data from a peripheral to memory, it would fll one buffer, inform the cpu and while it filled the second buffer, the first buffer would be sent to the sdcard.I want to do the same t...
Error initializing uart2 for STM32F072CBT6 processor
We wanted to use the uart2 serial port of STM32F072CBT6. We used the STM32CUBE tool to generate the code, but the debugging found that we could not enter the interrupt of uart2.We had no problem setting uart1 and uart3 to use before.The initializati...
Problem with SPI Serial Clock (SPI_SCK) signal not getting generated on H7
I have an app that uses SPI5 on an F7 chip with no problems, but it no longer works when I upgraded to the H7 chip (at the same time I changed to using SPI2).I am no longer getting the serial clock signal (SPI_SCK) on SPI2 on the H7 chip.I defined SP...
