Issue Programming STM32F04 through SWD

Hi all, I am trying to program the flash memory in my STM32F04 processor. I am doing this over SWD from another processor. I can successfully read all the DAP IDs etc and I also have figured out how to read and write from registers inside the stm32. ...

Flash erase and write is not consistent in STM32G030K8.

Hello, I am using STM32G030K8 for my application. So, due to bug in my code, out of bound flash memory address was tried for write and hardfault occured. But after resolving bug and resetting MCU, I observed that flash erase and write is no...

Where can I find MTTF or FIT rate for STM32H745XIH6? Thanks for answer. Marco

STM32F7 FMC SDRAM wrong reads

Hello,we have a STM32F7 interfaced to a CY62148EV30 SRAM with FMC bus.Sometimes, when several consecutive reads are performed, a wrong value is read.The wrong value has one or more bits at 0 instead of 1 (example: 0x52 is read instead of the correct ...

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

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...
