STM32 MCUs Products

Hello! I purchased the STM32G431RBT-Nucleo board. When trying to write code to control the DAC, I ran into a problem - regardless of the code change, the result is 0v, there is a straight line on the oscilloscope. The code itself runs on STM32F407. Do you

One of the variint main(void){ /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /...

How to jump to an application without reinit all previous initial modules

Hello guys, First i would like to thank you about your products and all the knowledge you share from your rich experience with us, really appreciate and helpful.I am using STM32L412RBPT evaluation board.This MCU has only 1 bank in the nvm of 128KByte...

Is system memory protected from read?

Recently we have received STM32F103RBT6/T7 samples which could not be flashed using internal bootloader. We have checked working devices and under 0x1FFF F000 they have readable bootloader firmware code. Problematic samples have FF bytes in the same ...

STM32F777 Parallel Bus Interface

Hi,I am working on STM32F777 MCU LQFP 176 Package.I need to confirm if i can use FMC interface with my EtherCAT chip FIDO5200 that uses 16-bit data lines and 4-address lines.Also I need to interface SRAM (parallel bus)that has 8-bit data and address...

Capture input PWM analog signal using Timers.

I have a specific requirement to capture input PWM analog signal using Timers.The timer should capture both period and duty cycle of the input signal for one pulse, then stop the capture automatically.The application can read the capture compare regi...

Backup SRAM duration

Hi STM,I am having short question about BACKUP SRAM on STM32F437 MCU. So, for how long will BACKUP SRAM keep data, if power supply is removed. Will the data stay there, after some long period or will they be wiped out?If they are going to be wiped ou...

CAN1_RX0 interrupt not firing

I've been working on getting the STM32f7-EVAL operational to later on migrate it to STM32F767II. For this we decided to split up functionality into 3 sections, there is a forward facing application that has the main and specific business logic.Curren...

Hello, I am using an ADS131E08 with stm32F7, is there any library (code c) that i can use to receive data from the adc ? Thanks in advance

Alternate Function 0 in STM32

In my STM32, if I have set the GPIO_MODER as "Alternate function" and did not set any values in the GPIO_AFRL and GPIO_AFHL, I guess it will take the defaukt value of AF0. What is AF0 used for ?

Unable to calculate the correct smooth calibration value for the RTC on an STM32F411. Can you spot my error?

Hello,  I am having trouble calculating the correct calibration value for my RTC 32K osc. My setup is as follows. STM32F411. 32768 LSE osc. I am passing a 1HZ signal out of the micro and I am measuring it with a 5Mhz precision oscillator and counter,...
