Hi, Now we want to use STM32F103 at -55C ambient temperature, MCUdata sheet say that it work at -40C as datasheet, storage temperature is -60C. My question is that,-If MCU is powered up at -55C, what will be different with>=-40C? Such as clock not st...
Using the IWDG within STM32L452 in its window mode.At some point the application needs to freeze the IWDG module functionality, or as a minimum make it work as in non-window mode.Is this possible? If yes, using which function?Note the I couldn't loca...
Hello, I am moving from TI DSPs to STM32 MCUs.I would like know if it is possible to configure SysTick timer to generate an interrupt with a period less than 1 ms, as I usually do on TI DSP projects.My doubt comes from UM2319, par 6.1.2:"SysTick time...
Is it possible to wake up from sleep when the UART receives one byte when I use cicular DMA?Or else I must catch every received byte using interrupt instead so it can wake up by interrupt.I'm using an STM32G030.
Given the surprising combination of these two RMs, I'm quite willing to bet there are more RMs out there with this.Nonfatal, but still.JW
I have configured TIM3 (using CubeIDE) in such a way that it generates an event that is used to transfer measurements on the ADC channels to memory using DMA. This works.But in the same time, I want to transfer to TIM3 CH3 the values in a table. The ...
I took SPI interrupt example from STM32CubeF1 repo. I have two Nucleo-F103RB boards. I am using one board as Master and the other as Slave. If I run the example as is then communication is working as expected. That is data from Master is getting sent...
