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 everyone ive been using STM32 microcontroller on custom boards for some while now, but particularly with the STM32G071G8 some boards are failing. After a few minutes, NRST seems to flicker and drop from 3V3 to 2,2, 1,7 and finally steady to aro...
Hello, I am using a STM32F401CE and would like to use the independent watchdog to cause a reset if the device would lock up for some reason. I have an external chip which is being controlled via GPIO and SPI from the STM32F401. When a watchdog rese...
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...
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...
Suitable drop in replacements:STM32F205VET7 /original 512 KBytes flash, -40-105CSTM32F205VFT7 /768 KBytes flash, -40-105CSTM32F205VGT7 /1024KBytes flash, -40-105C
I'm working on a bootloader which needs to erase and program the Flash. The erase seems to be 'working' but I have a suspicion that I'm not waiting long enough for the 'Busy' bit to go active after setting the 'Start' bit. The reference manual says I...
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;...
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.
Hi,I'm having an issue which I can't seem to resolve:I'm trying to change the output value of Pin9 (Port C) through an interrupt routine (TIM3).If I put a simple XOR statement for this pin in the interrupt routine it works as expected.However if I tr...
