Anyone know of a Flash read write example for STM32L4S5.Thanks

Resolved! Want to store data in SRAM D2 domain, what is missing to avoid Hard fault?

Instead of using DTCMRAM or SRAM D1 domain via AXI, I set up the linker file to use D2.In system_stm32h7xx.c I added the lines: /* Change the switch matrix read issuing capability to 1 for the AXI D2 target (Target 2 and INI2) */ *((__IO uint32_t*...

Storage time limitation for MCU STM32F051C4T6

Hello.As the MCU is very difficult to purchase this moment, we have a stock with about 2000pcs for STM32F051C4T6, however it was manufactured in 2013. It was 8 years in the warehouse, can we use it for mass production if the soldering process is not ...

Does the Wakeup from Standby work for 2 external events simultaneously in STM32L073 MCU?

Hi. I am using an STM32L073 based nucleo board. There are 2 external wakeup pins configured on PA0 and PC13 in this board which can be used to wake the device out of standby. If I write code to configure these two wake up Pins to wake up from the sta...

STM32L4R7ZIT exiting / returning from STOP1

Hello,I'm trying to understand which steps need to be taken when exiting the stop modes with STM32L4R7ZIT.Say that we are in stop1 mode, RCC->CFGR-STOPWUCK == 0 (MSI). Before entering stop1 we were clocked by HSE 12 MHz via the main PLL into 120 MHz ...

Using STM32F769 MCU as a SDIO host to interface with SDIO Slave (ESP32).

Hi,I am working on SDIO practically for first time, so I am using STM32F769 as a SDIO host and ESP32 as a SDIO slave. from ESP32 examples I was able to understand how to set the SLAVE config, but I am not understanding on how to start with STM32F769 ...

Resolved! Use a 14.7456MHz crystal with STM32G031 (32PIN) IO-Link application

Hi is it possible to use a 14.7456MHz crystal with a STM32G031 (LQFP32). If I'm right it is not possible at the data sheet, there is no OSC_OUT for this package. Or is the option missing in the data sheet? We need this crystal for an IO-Link applicat...
