I need urgent help on STM32L071 RTC power consumption. when we enable standby mode, without RTC, the current from battery is <1uA. when we enable standby mode, WITH RTC, the current from battery is ~200 uA ? Which is too high to sustain
The reference manual (RM0402, DocID028087 Rev 7, Fig 4) shows TIM3 as a 32 bit timer. However, the in the description in Section 17.2, TIM3 and TIM4 are described as 16 bit timers.Is this a mistake in Figure 4 ?Thanks
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...
