Hello, I want to use the ADC and the DMA on Simulink as follows: The ADC is triggered by the rising edge of Timer 2 which generates a PWM signal with a frequency of 100 kHz. So, I want to retrieve the 132 first data converted by ADC at every 1 second. Any idea how to use DMA (or buffer) on Simulink and how to retrieve the 132 first data… (Show more)

Hi All,   I am just getting started with stm32. I am using a stm32f031 mcu and am trying to read an input signal from a flight controller. The protocol used puts out a series of 4 pulses that vary from 1us to 2.6us in width with a 1us in between ( proshot protocol). I have used input capture with a timer for slower speed pulses but I have no luck… (Show more)

I am setting up a board that uses an STM32F103C8. It has an LED on PC13. I am running FreeRTOS and configuring with STMCubeMX. I am also enabling the LSE clock and RTC.   Using Cube MX I configure this and ensure that TAMPER is disabled/PC13 is GPIO and Output. I would therefore expect that PC13 (tamper pin) would behave as a GPIO and the LED… (Show more)

I have two projects, one from the F746G-Discovery Projects repo called FatFs_uSD_RTOS, and one created from CubeMX based on the template for the F746G-Discovery board with FatFS and FreeRTOS enabled.  The CubeMX project code fails to write to the SD card with the f_write function timing out after 30 seconds.  Of course, the FatFs_uSD_RTOS example… (Show more)

Hi,   I have the problem that many of us have as seen on the number of post on the forum. Unfortunatly for me nobody have the same issue as i have! Let s point out first what i'm trying to do. I'm on a small project of data gathering. Of course I need to store the data somewhere and the card won't have acces to LoraWan or any similar network.… (Show more)

Hi,    I am just Getting started with STM32F767ZI using a Nucleo F767ZI dev board. Prior to that I have only used in commercial project PIC24H family of Microchip and embedded C language. Can anybody help with how to get started with it.Following are the question which are coming into my mind and struggling to find much online material . How to… (Show more)

Hi guys, i'm looking to get signal from # FSR sensors with my STM32F4-Discovery. I set PA1 as ADC1_IN1 and after i associated DMA (with STM32CubeMX, HAL driver). So i generated the project and edited with System Workbench for STM32, added an int variable (fsrValue[1]) and in main, i started HAL_ADC_Start_DMA(&hadc1, fsrValue, 1);. It works fine… (Show more)

Hi, Please forgive as I am new to STM32 devices and tools. I was suggested to use a STM32 F0 Discovery dev kit (STM32F072RBT6) in order to develop a very simple application: a custom made 3 axles joystick (x,y and throttle). I have installed STM32CubeMX, SystemWorkbench for STM32 (SW4STM32) and followed all the steps without any problem until… (Show more)

The code produced by MxCube uses the systick interrupt to increment a tick count, (via HAL_IncTick())   But when  a projects is using a RTOS , the systick interrupt vector can be declared else where e.g. Keil RTX,  so it has to be removed form the Interrupt Service Routines file for example in stm32f1xx_it.c and HAL_IncTick() is no longer… (Show more)

Dear all I know that this is a very old question but after more than two months, I'm really sad... I'm developing a work (for scientific research) using a stm32f746igt mcu (from waveshare 746i) with several middleware/peripherals (freeRTOS, stemwin, usb hid, uart, spi, i2c, adc, timers, TFT controlled by fcm, etc...). Everything works absolutely… (Show more)
