SPI Strange behaviour with two slaves

Hello,I have a SPI interface with two slaves. This is my code: /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); MX_ADC2_Init(); MX_TIM6_Init(); MX_USART3_UART_Init(); MX_SPI1_Init(); MX_USB_DEVICE_Init(); /* ...

How can I see the STM32 MCUs production schedule for this year? Which MCUs will be the first to appear at distributors?

i2c implementation between MCU and sensor

I would like to read temperature and humidity values from TI HDC2080 sensor when using STM32L0F4 MCU. Programming language is C and environment is CubeIDE. I downloaded sensor library from dev.ti which includes a file where MCU specific I2C functions...

Good day! Can you tell me where to find information on the storage life / expiration date of STM32? Please tell me how to determine the originality of STM32 microcontrollers, by the markings on the case?

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.
