I am trying to use the SPI interface with a SPI ADXL345 sensor and the STM32F072 Nucleo board.I want to make a very basic read operation.Now the read function is blocked in waiting the the RXNE signal.But the RXNE is never set . SPI always read 0. I ...
Hi there, this is the default implementation of HAL_Delay function for stm32h7xx_hal.c (and I assume many other hals too)__weak void HAL_Delay(uint32_t Delay) { uint32_t tickstart = HAL_GetTick(); uint32_t wait = Delay; /* Add a freq to guara...
In my project after some time, I need to turn off the STM32F103C8Tx (or reduce it's current consumption as much as I can). Can I do it programatically? I do not want to change my hardware design.
I was to interface my nucleo with gsm module & send that data to another terminal ,basically 2 uart required please any one help me for that multiple uart with interrupt .If any code is available for gsm with stm32 also Please kindly share that for...
Hi, i am trying to get three analog signals using adc and dma in normal mode, when the buffer is complete I then process the information doing rms value, mean, std deviation etc.I have the PCLK2 clock at 84 MHz and clock prescaler of the ADC at 4, us...
Hi, i am using stm32h750 with eMMC Kingston EMMC16G-W525-E01U, as mass storage device. MCU and eMMC operates from 3.3V.I can put eMMC to 8-bit mode and it works ok, but maximum clock speed in 8-bit mode is 25 MHz. If i set clock speed more than 25 MH...
Hi,I am creating project in which I need to use LIN bus, I have tried to generate code from cubeMX, I have changed the BaudRate to 19200 in initialization, see the code from Initialization :static void MX_USART1_UART_Init(void) { huart1.Instance = ...
Posted on February 14, 2017 at 14:07Hi, I am working on ST STM32L151VB-A, I burned a loader which already worked for me, and since then I get ''active write protected STM32 device detected'' also on other application that worked fine. when I try to ...
Hey guys completely lost on this one. I have seen many other STM32 chipsets and in the reference manual its plain and simple how to increase it, however when it comes to this chip it doesnt list the Wait state for the CPU frequency but for the AXI pe...
