C++ and linker script

Hello All,I am using an STM32f767ZI device. I wrote a c++ program that has a base io class in which a gpio peripheral class inherits from the base io class. I call HAL_GPIO_TogglePin, HAL_GPIO_Init and HAL_GPIO_WritePin in the gpio class methods a...

How to check the GPRS HTTP commands in stm32 using UART

Hi, May I know how to check the GPRS HTTP commands are continuously working or not in stm32f103c8T6 using UART and How to put those HTTP commands in while loop. Plz help me how to do this.Thank you

STM32H7 SPI question - what is SPI1 CS on NUCLEO-H743ZI2 ?

User manual of  NUCLEO-H743ZI2 says that SPI1_CS pin is pin 16 on CN7 (D10) which is PD14 of the MCU.But in CubeMX, pin PD14 does not have any function related to SPI1.What does it mean? Should this pin be set up as GPIO output and driven manually?So...

[Bug Report] HAL uses incorrect GPIO pin control method in stm32fxx_hal_gpio.c

There is a bug in the ST HAL_GPIO_DeInit() function in stm32f1xx_hal_gpio.c, where it uses the CLEAR_BIT() macro to perform a read-modify-write of the GPIOx->ODR register directly to clear some GPIO pins, as opposed to the better way of clearing them...

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
