I am using a STM32F031 as a SPI slave device in close proximity to some motors that can cause some noise. I believe what happens is occasionally the STM interprets noise as a SPI clock which shifts my data one or more bits off. In the event I have ...
Hi all! We have created for you a new online-education program: STM32 step-by-step. It is a learning program, part of the STM32 Education initiative, designed for anyone interested in getting started on building projects with the STM32 microcontrolle...
I am trying to create an MDB / ICP (VMC) library for stm32f103 and I need to read and write 9600 baundrate 9N1 features! but hal_uart_receive () function gets 9 bits of data wrong! can you help me?
Hi, I am using the STM32F401RE microcontroller to control 4 seven segment displays which together represent a countdown timer.In order to control the displays I am multiplexing and therefore using the general purpose TIMER 2 in interrupt mode for a f...
I am working with the STM32F7 microcontroller and I would like to be able to send/receive 32-bit packets across an SPI-slave that is not using DMA. Will this be possible even if I can't guarantee to fill/empty the SPIx->DR register within a certain a...
Hello,can we use the STM32F2 series to read a sound file (e.g. wave file) from a flash or SD card and play ist via I2S?We would like to transfer the data from the DMA of the SPI into the DMA of the I2S.Best regards, Simon
I'm making a tilt-compensate compass using an STM32L476RG, an MMC5983, and an LIS2HH12. I am able to get a compass heading and tilt and roll angles but the tilt compensation seems to make the compass heading error worse. I have calibrated both the ma...
Hi Community,I am working on developing applications using STM32L4 IoT discovery kit. So far i am able to configure sensors and read data from it. Connect to WiFi and transmit data via mqtt are working fine so far. I am also interesting in implementi...
Hello,Here is my SPI configuration and interrupt codes:void SPIConfiguration(void){ SPI_InitTypeDef SPI_InitStructure; GPIO_InitTypeDef GPIO_InitStructure; NVIC_InitTypeDef NVIC_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB,ENAB...
Hello,I need to transfer 42 pulses (with 1 pin of a port) and read incoming bits from 1 pin of a port( such as SPI communication). As this forum member trained me I am curious to use DMA to generate 42 pulses with sending a specific value(10101...). ...
