STM32F7 - using SPI (slave) with DMA to set a flag (I.E. no interrupts)

We are trying to use SPI1 as a slave to receive 11 bytes of data per transaction. I.E. SPI1_RX --> my_data_array[11] When an 11-byte transaction is received, we want the DMA to raise a flag that we will check (we can't afford to use interrupts, a...

How can I process the TIM12 update interrupt in TIM8_UP_TIM13_IRQHandler? - MCU: STM32F767 -

The TIM12 update interrupt is not occurred in TIM8_UP_TIM13_IRQHandler().However it is occurred in TIM8_TRG_COM_TIM14_IRQHandler()I configured TIM12 update interrupt as below;//TIM4: master -> TIM12: slavevoid  MX_Test_TIM4_TIM12(void) {  NVIC_Enable...

After flashing done and removing jtag, our application is not working

I am using STM32F439NIHx MCU. After flashing the code, I removed ST-Link V2 from my PCand restart the MCU but our application is not working. But if I connect ST-Link V2 to my pc then my application is working. What is this problem? Please suggest a...

I appear to be having some issues with my DFSDM Manchester clock recovery. How do I set up the CKOUT for a 10MHz Manchester input? Do I need any clock connections or does it synchronize itself?

I am using the H7 and have a 10MHz sigma-delta ADC sending the Manchester signal. I do not have a clock going to the ADC because it generates its own.The internal DFSDM clock is set correctly, I think. I have a system clock of 96MHz and CKOUTDIV is s...

Hi all, I am fresher to STM32L4 Cortex M4 controllers i wants to know about timer configuration and basic codes for timers am search web cant identify anything please help me how sample code for simple timer based operations. Thanks

i am use a STM32H742xI/G mcu and i want to increase the buffer of the external flash memory how i do it?

what happens if more than one version of STMicroelectronics virtual com port driver is intalled on the computer?

I have 1.0, 1.3.1 and 1.4 version of the STM driver installed on my computer. How will it behave?

STM32G431 documentation issues

The pdf file of the STM32G431 datasheet (DS12589 Rev 2) has an incorrect Title and Subject (it uses 474 instead of 431). My pdf viewer (evince) shows the following:Title: Datasheet - STM32G474xB STM32G474xC STM32G474xE - Arm® Cortex®-M4 32b MCU+FPU,...
