STM32 MCUs Products

Hi, I am using STM32F401CC mcu. I want to erase the value of a specific flash memory address . Is it possible ? Is there any function like EraseFlashAddress ? Thanks

PWM+DMA to Generate a pulse output with a controlled number and adjustable duty cycle

I‘m configuring the timer pwm+dma output with cubemx, and I want to get a pulse output with a controlled number and adjustable duty cycle. and I used the above three methods, only the last two valid, but not the normal output.

How to Wake-up STM32L431RBtx from STOP0 mode?

Hi All,We have a project using STM32L431RBtx. In that we are trying to put MCU into sleep mode by using HAL API: HAL_PWREx_EnterSTOP0Mode(PWR_SLEEPENTRY_WFI) in bare-metal code base.Here the interrupt we have configured to wake-up the MCU from sleep...

STM32F427: ADC ERROR (ADC1 = regular + injected) + (ADC2 = injected)

Hello,I want to convert on ADC1 some channels in regular mode all the time. After a last Transfer request DMA2 Stream 0 should write all converted values in a global buffer. I also want to convert four ADC channels synchronous with injeced mode. So I...

I think IWDG Dosen't work

My board(STM32F103R8T6) sometimes stop.. So I use IWDG and it doesn't work. If my board doesn't work well, is it right that iwdg works and resets the core? Let my code work properly.void IWDG_Configuration(void) { IWDG->KR = 0x5555; IWDG->RLR = 0x...

STM32F072 LSI Calibration

Hello, I recently started with embedded programming and currently I'm tasked with LSI Calibration based on LSE clock, this would be useful when the device enters low power mode. Based on this reference manual:https://www.st.com/content/ccc/resource/t...

STM32G474: Descriptions on access paths to SRAM2 is inconsistent within a data sheet.

DS12589 Rev 1 (for G431) and DS12288 Rev 1 (for G474) both states in Section 3.5 that SRAM2 can be accessed by CM4 core through System Bus or through the I-Code/D-Code bus. However, Figure 2 "Multi-AHB bus matrix" suggests that SRAM is only accessibl...

How to swap two memory regions from different banks in FLASH Memory for STM32L475?

Hi,I am working on B-L475E-IOT01A2 which is a STM32L475 series Discovery IoT kit and has an ARM M4 cortex. It has two banks of FLASH Memory of size 512 KB each. I am implementing two applications along with a bootloader and all of them are stored in ...

i work on a project with stm32l010f4 how can i get a regulated stable voltage from one of its output pins?? how can i get VREF as an output for adc?? is there any code for this??
