I am trying to read an analog signal from a sensor with the ADC of my board. I set the pins correctly I think ( DMA_continuous_requests enable, circular mode, etc. ) and I started the DMA with HAL_ADC_Start_DMA outside the while(1) loop and I put a b...
I am working with a Nucleo-L476RG and I am using PuTTY as an interface using UART. I am trying to use PuTTY to read a numerical value from the user and then store that entered value in a variable. Below is how I am initializing UART to receive user ...

I am trying to use the I2S2 interface in Master Rx mode with the Nucleo 401RE and X-Nucleo-CCA02M2 audio shield. I enable the SPI2 global interrupt in NVIC settings, setup the required GPIOs and generate the code. I want to receive data from the on-b...
I'm trying to configure and collect data from a BNO055 IMU over UART/RS232, using an STM32L552ZET6Q. The BNO055 is on a remote board, connected via cable to the STM32L5 microcontroller. Additionally, I am using a MAX3232CUE+T on either side of the ca...
Hi! I am working on a project using a STM32f407 board, I wrote the code but when I try to load it, an error shows. I saw a similar problem but the solutions didnt work for me. Here is the build output
We uses a custom hardware with STM32L496AG. It seems like the board hangs after initializing the clock. We think the issue is SysTick fails to increment the tick and hence tick related functions are not working. Please see the attached screenshot of ...
Hi, I am trying to use a 4 I2s microphone. And I am using cubemx.I made work both of them with a sinple DMA transfer.I used I2s half duplex reciever 16of32bits sample rate 48Khz and DMA for 48*2 samples with uint16_t format. For that I used DMA1 str...
I implemented a code of output compare mode for TIM3. However, it does not work as I expected.ky017ledmodule_config.h#ifndef KY017LEDMODULE_CONFIG_H_ #define KY017LEDMODULE_CONFIG_H_ #include <stddef.h> #include "stm32f4xx_hal.h" #define RED_LED ...
Hi,how can I tell to the compiler that I want a function to be executed in RAM ?
