STM32 PWM to stop after n pluses

Is there a way to stop STM32 PWM after 10 pluses ?I know one solution is using the system time and issue a stop via the code, however my issue is the stm CPU might be very busy to handle the stop signal.

Run the RTC clock on nucleo board

using a 32 KHz low-speed external crystal to run the RTC on STM CubeIDE.

SWD Pins on STM32L476RG

Instead of using JTAG, I would like to enable SWD programming (via STLink) for a custom STM32L476RG board that I am designing. Which pins of the MCU correspond to the 5 SWD pins normally found on boards like Nucleo and Sensortile? I probably found ou...

HAL_IWDG_Refresh causing the MCU to crash

I have my prescaler set to IWDG_PRESCALER_256 and Reload set to 16000Far before that counts down to 0 when I call HAL_IWDG_Refresh the program crashes.I am running on an STM32L072CZTAny ideaS?

Read Analog Sensor Values STM32

Hello, i am making a project on a stm32 (STM32F767ZI) development board, and i need to read analog voltage from 9 sensors. I have been reading the datasheet to see if is there a ADC mode that can make the process faster and more optimized. The most b...

Canbus Transmission and Receiving Problem

I have a project which is include Stm32f4 and CAN Trasceiver and I also using CAN Analysing to analyse the line. And I also have 120 Ohm.When I configure CAN1 and try to send CANBUS data with canheader.DLC = 8; canheader.IDE = CAN_ID_STD; canhead...

Is stm32 disco board supports CAN Communication?

Does Level 1 Read Protection mean I cannot backup my program from flash or have an IAP application?

I'm using a Nucleo F429ZI and I'm using a dual bank configuration. I'm trying to make sure I understand the read protection levels. If I want a feature that allows me to save a program written into the other bank (e.g. save it to a usb as back up), i...

STM32 USB HID host with CP2110 - problems with modyfing the code

Posted on April 30, 2018 at 23:15 Hi, I have a project where I need to communicate with CP2110 via USB (medical device having this interface). I am prototyping the application on STM32F746G-DISCO. I have started by running the Application exam...

how to terminate I2C master-receive transaction?

target CPU: STM32F427IGI set up STM32F427IG as master receiver via DMA. I wait on "DMA_GetFlagStatus(I2Cx_DMA_STREAM_RX, I2Cx_RX_DMA_TCFLAG" to figure out if I received what was sent.After running for 20 minutes or so, I2Cx_RX_DMA_TCFLAG flag does n...
