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...
Resolved! Enabling USART2 on STM32F413
Hello!I am wondering what the high level process for enabling a USART port is. I am enabling RCC_AHB1ENR_GPIODENRCC_APB1ENR_USART2ENBut the TX line stays low. I am guessing it has to do with the clock?Thanks
[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(); /* ...
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...
