Enabling automatic, regular wakeup with RTC timer

Dear community,I have some issues with implementing an automatic wakeup with the RTC timer on my STM32L476RG (currently on the Nucleo-Board, will be later replaced with proprietary hardware). I generally have two wakeup sources: either the L476 is wo...

STM32f469 SDRAM Read/Write issue on FMC Bank2

Hello all,I have W9816G6JH( Winbond) SDRAM interfaced with STM32f469 on a custom board.SDRAM is interfaced on FMC Bank2.I have generated SDRAM initialization code for MDK-ARM using CubeMx. When I Write and Read back on SDRAM address 0xD0000000 it sho...

Are there resources to more easily understand peripheral versions used across families?

I use a lot of STM32s in my work. The reference manuals, datasheets and so on are excellent but often contain a lot of near repetition between families. What I mean is that the details of the registers for (say) GPIO are often identical. But not alwa...

How to set the option bytes in STM32G0B1KE MCU to change the boot configuration through i2c in-application programming?

STM32F407 - Question of how to use 3-wire SPI

Hi,My slave device has only one bidirectional data line. Now I want to configure the SPI in the half-duplex mode. And I noticed that the reference manual gave an descripiton of 1 clock and 1 bidirectional data wire.I want to ask if ST has peripheral ...

STM32 MCUs can operate in vacuum environment?

Hi,​I would like to know if MCUs of ST can operate in a vacuum environment.​Thanks​

SPI stops working when enable I2C?

Hello, I'm trying to use I2C and SPI simultaneously on an STM32F103C6TX.Both are working properly when only one of them is activated. However, when activating I2C peripheral with SPI already activated, SPI clock still works but the MOSI pin stops wor...

STM32 memory out and how avoid that

Hi there,here i'm for ask another help. I compile my program with keil and i read this data :Program Size: Code=15988 RO-data=360 RW-data=24 ZI-data=2088  How i can interpret ? I use one STM32G031F4P6 wher i have 8K of RAM and 16K of program. So i ju...

Which STM32 controller has secure booting capability?

Im currently building boot loader to securely boot the firmware by signing the firmware images and verification during the boot of the firmware.So i'm using controllers like stm32f411,stm32f446,stm32f746 and stm32h723 ,I believe from the available do...

Timmer input STM32F429

Fig 9 of the STM32F429 datasheet it effectively states that the external source clock/signal has to be 1/3 of the Timer clock – makes sense as you want to ensure you capture the edge of the input signal. However, the Ref manual section 17.4.3, the re...
