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...
Hello,I'm using STM32H757i-EVAL board and trying to store some data in the onboard SDRAM using stm32cubeide (1.7.0).Below is my initialization for SDRAMvoid MX_FMC_Init(void) { /* USER CODE BEGIN FMC_Init 0 */ /* USER CODE END FMC_Init 0 */ ...
Hi ST Community.I need your help. I am working on a PWM Proyect, Duty cicle must be change every period, and there is delta time where the PWM must be OFF.I am using a Timer, it fire an interrution and this interruption set a flag to 1 in order to r...
i've created 2 threads - i2c_tx_dma and i2c_rx_dma which use the HAL_I2C_Master_Transmit_DMA and HAL_I2C_Slave_Receive_DMA.I am working with 2 boards of the STM32h74 family:first board-> configured RX DMA on i2c1 block as a slave and activate HAL_I2C...

Hello,I have question about QSPI on stm32F446.I want to connect serial flash with QSPI.there are 2 banks on QSPI.When I try to find some example on QSPI, they were all used QSPI bank1 connected to s/f memory. But when I check pin connections on QSPI ...
I want to interface Stm32 MCU with a NXP MCU over SPI protocol.Does anyone have done that before?? If yes can you please tell me how it can be done? I have already used St and nxp mcus separately and now my application requires both of them together....
Hello ST Community,I am using RTC backup register of STM32F746ZG for saving some accumulating data.So i'm afraid of situation when i start write operation and in the same time the VDD power is disabled.Couldn't find any information about this, so i a...
Bottom of page 299 in the H7 Ref Manual says pretty clearly that "In Standby, all I/O pins are high impedance without pull" except for a few WKUPs and Reset. Okay, this sounds like I'm out of luck for holding peripherals in low power states. But the...
I'm looking for some more information when it comes to the STM32 OctoSPI support for Regular command versus HyperBus protocols when it comes to interfacing with an external PSRAM in Memory Mapped mode.We are considering a ISSI OctaRAM part vs HyperRA...
