STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello, I am using STM32L475 board and trying to communicate with VNF1048F by SPI. The communication protocol which is used is defined as ST-SPI. On STM32 I can configure at maximum 16 bit communication but the device (VNF1048F) requires 32-bit frame...
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...
Hi all,I need to control 3 BLDCs on one board. I found that in order to precisely control BLDCs, you need a board with special motor control timers. I have only been able to find boards with two of these timers (Example NUCLEO-H745ZI-Q) but I need on...
