STM32 MCUs Products

Hi Team, I'm using a STM32L4R5 and am wanting to store variables in SRAM2 as static variables so that they hold their value while the micro is in standby mode with SRAM2 retention enabled. What am I missing?

I've followed every tutorial/thread that i've been able to find but cannot get this to work. I've set: RAM2 (xrw) : ORIGIN = 0x20030000,  LENGTH = 64Kand .ram2_bss : { . = ALIGN(4); *(.ram2_bss) *(.ram2_bss*) } >RAM2In STM32L4R5ZITX_FLASH.ld and defi...

SDIO 4 bit DMA UNKNOWN PROBLEM

This is sd_command line via logic analyzer. I'm writing 1024 bytes every second. But sd_commend do like that. And that's problem for me. If i wanna save some datas. sd_command line spoilng and locking my stm32f411 mcu's. I need help i don't understan...

Hi ST Micro Would like to buy production qtys of STM32F205VET7 for 3 of my designs, cannot wait another year for delivery. Is this semiconductor still being produced OR do I need to re-design around it please. Scott_Davidson@Trimble.com

Hello. Does anyone have a configuration example for stm32f103 uart in half-duplex mode(switch TX/RX modes) using Low Level Library. Thanks!

Could not set IWDG timeout to max (~32s) for STM32G031?

I am using Nucleo-G031K board and attempt to set IWDG timeout to max value of ~32s. Got hard fault. Here is the code. Any idea?  iwdg_hIwdg.Instance = IWDG; iwdg_hIwdg.Init.Prescaler = IWDG_PRESCALER_256; iwdg_hIwdg.Init.Window = IWDG_WINDOW_DISABLE;...

STM32F072RB in I2C slave mode

I am using STM as i2c slave. When other i2c master reads, first byte is always 0xFF and rest are correct data from STM with 1 byte shift so master needs to read 1 extra byte. Also I get HAL_I2C_ERROR_OVR error during that. Please suggest.

Multiprocessor mode with address mark detection only receives data which has '0' as MSB. After waking up (RWU=0) when the correct address is received subsequent bytes should be received normally, and not interpreted as another address?

I have configured the UART for multiprocessor communication over RS485. I can receive and transmit data correctly, but if the data contains a '1' as MSB it is interpreted as an address. Now it is clear from the documentation that this is the correct ...
