STM32 MCUs Products

ADC can be executed with perfectly syncronized with internal PWM generated from STM32 MCU?

HSE startup timeout on STM32F103RET7

I'm new to the STM32 so I apologize in advance for the trivial question.In the following code from SetSysClockTo72() system_stm32f10x.c, the value for HSE_STARTUP_TIMEOUT is 0x0500.  What max delay (msec) does this equate to? /* Wait till HSE is read...

Why on STM32L053, TIMER22 generates an update, CC1 and CC2 event when counter is enabled?

I want generate an event when the timer counter is at CCR1 register or ARR register.But when the counter is enabled, the timer generates all events. Can you help me?This is the init routinevoid init_timeout_timer22() { RCC->APB2ENR = RCC->APB2ENR | ...

STM32F429 shorted unexpectedly

I was working on the MCU STM32F429 while it was connected to the PCB when it shorted unexpectedly. The PCB at the time wasn't being used to power the board, or drive the motors. The Power source was my laptop and no external batteries. The USB cable ...

Having issues with using simultaneous timers

In my nucleo L432KC, I have set Timer 1 for PWM generation, Timer 15 as a timer based interrupt and Timer 2 as PWM input mode. Timer 1 and Timer 15 works well until a point. For example, I wanted a 50 kHz update event, so I set Timer 15 Precaler 0 an...

I have a design with STM32F427IIT6 and I would like to upgrade the MCU. I need one MCU that is fully pin compatible. What is my best choice at this moment in the F7 and H7 series?

STM32F105 USB HID host

I'm developing HID Host for working with standard PC keyboards.I face with problems in function USBH_HID_GetReport from cubemx, it never returns USBH_OK. Absolutly same problem explained here http://forum.easyelectronics.ru/viewtopic.php?f=35&t=23447...

CAN I use USB OTG_HS with internal FS PHY and get RX DMA?

In the FS mode the reference manual state that  USB RX DMA is only available in HS mode. In MXCube it seems that I can set USB OTG HS and set internal Phy to "device only". Does this activate the RX DMA? ​It also seems to change the pins assignment o...

Interrupt problem

Without Interrupt signal STM32F207 print continuously.How to avoid it...void EXTI9_5_IRQHandler(void){ /* USER CODE BEGIN EXTI9_5_IRQn 0 */ /* USER CODE END EXTI9_5_IRQn 0 */   printf("\n\rInterrupt Occur\n\r"); /* USER CODE BEGIN EXTI9_5_IRQn 1 */ /...
