    Try using a USART on APB1, and have APB1 running at 18 MHz (ie 72 / 4)

    BRR = 18000000 / 300; // 60000

    Calculate and compare ;)

    32 bit value would not fit in 16 bit ;)

    hi,

    Everyone

    PLLMULL=PLLSRC*2

    PLLXTPRE=HES/2

    //main

    USART1->BRR=((unsigned int)(12000000/(16*300)))<<4;

    //it is work :)
