We are using STM32G051 to measure duty cycle of the actuator PWM signal.TIM1 is configured in slave reset mode, with CH1 direct capture on rising edge and CH2 indirect capture on falling edge. Two DMA channels transfer results into two memory buffers...
Posted on September 26, 2017 at 02:56Hi there,I am attempting to get an STM32F411CE microcontroller to interface with a BNO055 IMU using the I2C peripheral. This particular IMU uses clock stretching which doesn't seem to work with the HAL_I2C librar...
I'm using STM32L432KC on Nucleo-L432KC board with the following set up:I2C -- PB6=I2C1_SCL, PB7=I2C1_SDASPI -- PA1=SPI1_SCK, PA11=SPI1_MISO, PA12=SPI1_MOSI, PB0=software CS for SD card readerEXTI - PB1=EXTI1It all works fine until I want to configure...
Hey, I am working on a project using the STM32F746 chip and writing and reading to/from an SD card. When reading from the card is completed, HAL_SD_RxCpltCallback is executed, which provides output by sending bytes over UART 8 line. When I read from ...

HAL_SPI_TransmitReceive_DMA() can lead to non-functional DMA when the following happens:RX DMA state readyTX DMA state busyHAL_SPI_TransmitReceive_DMA() gets calledThe result is that RX DMA will become busy and never recovers due to the logic in line...
Hello everyone,I am facing an issue while trying to interface a 24-bit PCM mic with the STMH743ZI2 microcontroller using I2S2 in master receive mode with 24-bit data in a 32-bit frame(set using CubeMX). Although I have placed the I2S buffer in the ad...
Hello! I am working on PWM generation using several timers, in this case: TIM3, TIM4, TIM8, TIM15. I have gotten TIM3, TIM4 and TIM8 to work perfectly. I am currently testing this on a STM32F3DISCOVERY board. TIM15 however, does not behave properly f...
Hi fellas,I'm interested in implementing the firmware upgrade over the air (OTA) over BLE. I've came across dedicated STM's MCU family STM32WB too. But I'm more concerned about implementing in STM32L0/4 series family of MCU. Which MCU would be suitab...
Hello everyone. I'm trying to use the TIM6 as a timer at 1 kHZ. However the result I get is 500 Hz. I couldn't figure out why. I maxed the CPU clock speed at 168kHZ, which gives me the result of 84MHz APB1 Timer Clock. I calculated the auto reload va...
