Hi, I would like to separate the project files (.project) and source files into different directories as shown in the image below. How can I do this? In my original project, I don't want my source files and project files (.project) to exist in the s...

Hi, When compiling program using Keil IDE, understand that the program size that flash to MCU can be calculate by:Program size = Code + RO + RWHowever, when compiling using STM32CubeIDE, how to know the program size going to flash into the MCU flash...

Hi , I am using TIM21 in input capture mode to measure the LSI frequency (~37 kHz). However, when I set the TIM21 clock to 2 MHz or use the MSI clock, it causes a hardware fault when attempting to capture the LSI frequency.I have reviewed the STM32Cu...

Hi,Does anyone know if it's normal for the RTC_IRQHandler not to trigger when the MCU wakes up from standby mode using the wake-up timer? I tried setting a breakpoint in the RTC_IRQHandler, but the problem is that it doesn't hit the breakpoint when t...

Hi, I'm using STM32L0 series MCU to configure the RTC to wake up after 24 hour during sleep/standby mode. Understand that we need to configure the Wake up clock to use 1Hz with 1 bit wake up counter added so that it can have the wake up time from 18h...

@mbrossett , Correction : It is necessary to start the base timer interrupt separately to work correctly.

Good to know! Thanks, it's very important to check the parameters/variables in a function to prevent overflow before processing them

Hi @mbrossett , why do we need to start the base timer? Since HAL_TIM_IC_Start_IT() already enable the Input capture interrupt.if(HAL_TIM_Base_Start_IT(&Input_Handle) != HAL_OK) { Error_Handler(); }

@mbrossett , I have tried start the base timer before start the input capture, it is working with moving out the frequency calculation out of ISR.

Hi @mbrossett , After reducing the execution time of the ISR by moving the frequency calculations to the GetLSIFrequency() function as you suggested, the LSI frequency is now detected correctly with a system clock of 2 MHz. May I know the main reason...
