STM32 MCUs Products

I am trying to read Vbat(battery voltage) using ADC in STM32F042 ,the reading always is Zero. Anyone please find the reason for it.The code is as follows..please dont metion the syntax error ..i have copied only the necessary parts

void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc){ if(__HAL_ADC_GET_FLAG(hadc,ADC_FLAG_EOC)){ adc_value=HAL_ADC_GetValue(hadc); }}main(){ HAL_ADC_Start_IT(&hadc); while(1) { }}static void MX_ADC_Init(void){ ADC_ChannelConfTypeDef sConfig =...

I want to make a large order of components in Russia. I can't find a distributor with the components: STM32L433RCTx or STM32L443RCTx or STM32L452RCTx or STM32L452RETx or STM32L462RETx in stock. Tell me where to find the components, from 100 to 1000 pieces

I am converting a project built on an STM32F072 to an STM32L071. I use a small area of flash memory to store some tables, etc. < 100 bytes. The program using the STM32IDE works fine for the F072, but I get a Hard fault with the L071.

I am using page erase and HAL flash program functions

STM32H7xx I2C driver with DMA not working

Hello,i use STM32CubeIDE with FW 1.60 with and want to use the I2C driver with DMA to read and write some data do a device.I configured it properly in CubeMX and the code has been generated and all interrupts etc. are implemented.When i test it with ...

What is Radc of STM32L431 at 3.3V (value is missing in datasheet)

Hello,I would like to optimise my conversions to have a minimum phase shift between them. I have taken the application note AN2834 but I miss Radc. There is Cadc and Rain max but this data is not in the STM32L431 datasheet.Thank you in advance.

Hello, I want to read data by STM32H745BI from external ADC AD9235 with parallel interface. I suppose to connect by FMC. Tell me please how to connect correctly and choose right FMC Mode and Configuration in STM32CubeMX. Thanks!

is there any efficient way to wake-up the STM32L0 from STOP-Mode by UART Rx Interrupt?

As I used HAL_UART_Receive_IT() function to receive data in interrupt mode and with that enabling the UART Interrupt using this "__HAL_UART_ENABLE_IT(&huart1,UART_IT_RXNE)" .Still not waking up the MCU.Please let me know if i am missing something and...

Touchgfx: I am displaying a double in a Text area but cannot get more than 6 decimal places

Hi,I am using a text area to display a precision timer output (double) and need 8 decimal places of precision. Thye best I can get is six:I have a wildcard buffer of twenty and the following code:/* Backend code */   typedef struct {   volatile uin...
