Introduction The real-time clock (RTC) can be used as a source to periodically wake-up the microcontroller, perform necessary tasks, and then return to low-power mode. Furthermore, the RTC can be used to calculate the elapsed time while the microco...

Hello @Sushmita, you probably solved this issue and got ahead in your project, could you share with us what was the issue? I would say that it was mandatory to enable the deadtime preload bit in TIMx_DTR2 register to enable the deadtime value preloa...

Hello @skuma.8, sorry for the delayed answer, Is there any news about this? Is the timer started with the interrupt enabled? Using the HAL_TIM_Base_Start_IT function?

Hello @damha, a) Although am not a design expert, your connections seem correct for interfacing the encoder inputs to the MCU, however, it would be better to double check with asking a separate question here: STM32 MCUs Boards and hardware tools - S...
