Hello. I am currently working with the STM32L031 Nucleo board:https://www.st.com/resource/en/user_manual/um1956-stm32-nucleo32-boards-mb1180-stmicroelectronics.pdf The board has integrated ST-LINK so it is quite easy and convenient to flash the devic...
Hi,I am using B-L475E-IOT01A. I am wondering that MSI can be changed on the fly when it used as system clock source.In `HAL_RCC_OscConfig` from STM32L4Cube drivers code, it looks like ok. But I didn't find any relative information from l47xxx manual....
firstly i am new to here, dont know much rules about posting. 1 minute ago i saw post about shorted power dont kills mcu but can it damage stm32?so i shorted my 3d printer board(stm32g0b1ret6 probably) via 3.3v and gnd(general probably). i checked by...
Hello all, I have designed a board for sensing purposes and I am using the following ST components: STM32U575ZIT6Q. I am supplying this component with 3V3, which I get form a 5V/3V3 LDO. Between the output of the LDO and the supplying rail to the STM...
I have a test project that sets up TIM3.3 to count microseconds between falling edges of the timer input. The timer is started with a call to HAL_TIM_IC_Start_IT(&htim3, TIM_CHANNEL_3); to start timing the input. Inside HAL_TIM_IC_CaptureCallback(*...
Hello everyone,I'm working on a project with a STM32L072CBT6.I'm using LPUART (PB10 / PB11) at 9600 bauds to communicate with an other board. For low power consumption, i'm using LSE for my LPUART.When i check my bauds rate on my oscilloscope, i get ...
Hello,Is there any specific guidance regarding how to improve wakeup time from the various STOP modes? The U5 Reference Manual mentions that configuring STOPWUCK = 0 will use the MSIS up to 24 MHz, which would be faster than HSI16. I've used that alr...
I noticed this in the NUCLEO-L452RE schematics. The external capacitance added to the ABS25-32.768kHz crystal is 4.3pF. Could someone please explain the reason for this?I've learned from the datasheet of the ABS25-32.768KHz crystal that a capacitance...
Hi.I use the STM32G474.To start TIM1 synchronized with HRTIM, I will use "hrtim_out_sync".I have a question.If I use "hrtim_out_sync", Can I start TIM1 at same time and reset ?I want to set a same frequency for HRTIM and TIM1 and start simultaneously...
The STM32U5 has HS PHY and it's slower than the STM32H5 so why doesn't the H5 have HS PHY or any HS USB support? Will a version that does be released in future? Its almost the perfect chip to use for a future project I have in mind aside from the lac...
