Start multiple ADC's DMA
I have tried to get ADC results from 8 different chanels on 3 ADC's using DMA so that the fresh values are always avaliable to me on STM32F303I used Cube MX to configure the ADC's and DMA's. After initisalization I did: HAL_ADC_Start_DMA(&hadc1, (u...
Resolved! Entering and exiting stand-by mode on interrupt
I'm a beginner in embedded systems. I'm creating a software where some leds are blinking in the main while loop. I would like to put the MCU into stand-by mode when connecting a certain pin. I want to return to normal execution when this pin is disco...
stm32 series rotary capacity sensor touch example
Hello, I am currently developing a medical devicestm32 device related rotary capacityCircuit diagram and example code related to touch sensorIs a mustNo matter how much I look for it, there is an example related to the Liner touch sensorAs there are ...
Failure debugging a program using a Nucleo-64 STM32L476RG:
A program, using the Nucleo-64 with STM32L073RZ, gives no problems, another program, even a blank new project, with Nucleo-64 with STM32L476RG gives "Failed to execute MI command:target remote localhost:61234Error message from debugger back end:Remot...
File transfer over the UART.
I want to store a hex file into the flash memory, For that I am trying to transfer the file over UART from computer to controller.what should be changes to be made in source code?or what should be approach?I am using stm32l083cz microcontroller.Thank...
DMAMUX to DMA channel/stream numbering discrepancy
In the single-port DMA, transfer units (to which requests correspond) are called Channels and they are numbered 1-based.In the dual-port DMA, transfer units are called Streams and they are numbered 0-based.DMAMUX documentation in various STM32 models...
Speed different when accessing Peripheral Register (i.e. GPIOx_IDR) vs using DMA to copy GPIOx_IDR to SRAM?
Hi Experts,May I know is there any speed different between access direct to Peripheral Register like, GPIOx_IDR? with access directly to SRAM ( using DMA to do Peripheral to Memory)?From this block diagram, the GPIOx_IDR is using AHB1 bus and it runs...
Inaccurate frequency meter
Hi all, I am trying to implement a frequency counter using an STM32F446 and STM32CubeIDE. I am following the reciprocal measurement approach of one STM32 tutorial available in internet (see screenshot). Basically, i am using the input capture mode t...
STM32F4 Accelerometer issues using an RTOS (HAL SPI problem?)
Posted on December 06, 2016 at 19:53 Hello, I have managed to create a program (using Keil), that can turn LED's on and off based on the orientation of the MCU. However when i try to implement the program as an RTOS with threads, the program d...
