I'm currently try to set up a project for smooth calibration on a Nucleo-L476 like in the smooth Calibration example AN4759. Same Board, same code but it doesn't work. Do you may have a guidline or ioc file?

Hello @THart.3​ ,

Please you mean this AN : Using the hardware real-time clock (RTC) and the tamper management unit (TAMP) with STM32 microcontrollers?

You can check the available examples in the FW for the STM32L476 : STM32Cube_FW_L4_V1.17.2\Projects\NUCLEO-L476RG\Examples

Hi. Thanks for your answer.

Yes there on page 40 is the Smooth calibration example with the Nucleo-L476 and I'm working with this project.

I made a little progress, in the tim.c file they used LSE as clock with following instructions:

TIM2->OR1 = TIM_TIM2_ETR_LSE;

TIM3->CR2 |= TIM_TRGO_OC1REF;

I wrote these in the wrong fuction. Now i just have the problem, that in the TIM2_IRQHandler:

if (__HAL_TIM_GET_FLAG(htim, TIM_FLAG_CC1) != RESET) that it never goes in into this if query, but the interrupt occurs.

Hi thank you for your answer.

i already read that thread, its very usefull for understanding.

i just have problems to implement the smooth calibration in my project.
