Resolved! How to reset SPI interface after HAL_SPI_TransmistReceive_IT?

Hello,I'm working with a STM32F446 and I configured the SPI as slave.In my process I receive x bytes of data in interruption. But during the process, this size of data changes to y. But the function HAL_SPI_TransmitReceive_IT(x) has already been call...

using STM32L0538, is it possible to make SysTick_Handler count in microseconds not in milliseconds and if it is, where to start?

I'm writing some code with PWM and I'm using very high number of periods in short time causing my LED's to dim very choppy. I think it's not working properly because timer is to fast and counting in milliseconds and I need it to count in microseconds...

I just realized workshop is at 8:30 AM CET time. I live in the USA; with time difference of T-8 hours (to USA MDT) time is 00:30 AM. I bought the Evaluation Nucle-H7 board required already, is there a way to record the workshop/webinar video?

I would be more than willing to participate regardless of time, but due to health reasons I can't stay up all night. I really need the workshop to get up to speed on the STM32H7 for a project I am working on. Thanks!
