STM32L011 in low-power and "Target is not responding, retrying ..."

I'm using Nucleo STM32L011K4T6 kit to test different low-power features.For this, the code is executed in RAM for 10ms (GPI/Os management) then the MCU is put in stop mode with the WFI instruction, to be woken up 90ms later by the RTC (RTC wake up).T...

how do I fix an interrupt that fires multiple times on EXTI4-15

Hey,I am using nucleo F030R8 om window os.I connected buttons to the board and i proggramted that each push will trigger an interupt(rising and faling). However many times i can see the the unterupt callback function is triggerd twice(2 calls for on...

STM32H7+DMA+UART – which stream ?

Hi there,can anyone assist in understanding how to choose the correct ‘stream’ for an STM32H7 + DMA + UART setup, please ?I’m continuing work on a previous colleague’s firmware where UART1 was programmed to operate in DMA mode. This needs to change t...

i have trouble with viper222 spice model when i import to simetrix i get this error message: There are errors in the model library. Some models may be missing File: VIPER222.lib, line: 1002: Unknown type in .MODEL 'DACModel'

udp_client on stm32 h753 nuclio board

hii i have stm32 nucleo-h753 board and i finally managed to set the project in order to work with the ethernet port .i can ping the board successfully , so my next step is to send udp message from the board to my pc .i use herculis as my udp server ...

Double precision computation

I'm using STM32F446xx 32-bit MCU, but I want to do computation using double precision. Is it possible to perform double computation precision using given MCU? And if so, how can I make sure that double computation is performed?

STM32H7 SPI interface to Flash Memory Winbond W25Q64DV

Hi team, I am using stm32h7a3 MCU and I am trying get manufacture id from external SPI flash(W25Q64FV).But problem is if I used SPI mode 0 then its working properly but If I used mode 3 then it is not working, However in windbond datasheet says its s...

Are there are any examples available for CORDIC (STM32G4) in DMA mode using the low-level drivers.

Hi, Are there any examples that use CORDIC with Low-level drivers? Thanks
