    Hello,

    You have chosen the correct example. Could you share more detail about the facing issue please ? Which hardware are you using ? It seems that you are sending result via UART with timer interrupt which could be helpful if you are facing unwanted behavior....

    Here some additional lecture to STM8S AN2822 :
