you are right! tim3 is not running;
<BR> // Set the AHB clock (HCLK) equal to the system clock (SYSCLK).
<BR> // Set the (high speed) APB2 clock (PCLK2) to the system clock.
<BR> // APB2 can run up to 72MHz.
<BR> // Set the (low speed) APB1 clock (PCLK1) to the system clock/2.
<BR> // APB1 can only run up to 36MHz.
