stm8 pwm实现核心代码

void TIM2_Config(void)
{
        CLK_PCKENR1 |= 0x20;//TIM2 CLK Enable!
        asm("nop");
        while(!(CLK_PCKENR1 & 0x01));
        TIM2_CR1 = 0x00;

        TIM2_PSCR = 0x00;//16/2^4

        TIM2_ARRH = 0x00;
        TIM2_ARRL = 0xFF;//

        TIM2_CCR1H = 0x01;
        TIM2_CCR1L = 0xf4;

        TIM2_CCR2H = 0x1;
        TIM2_CCR2L = 0xf4;

        TIM2_CCR3H = 0x01;
        TIM2_CCR3L = 0xf4;

        TIM2_CCMR1 = 0x70;
        TIM2_CCMR2 = 0x70;
        TIM2_CCMR3 = 0x70;

        TIM2_CCER1 = 0x33;
        TIM2_CCER2 = 0x03;

        TIM2_IER = 0x00;
        TIM2_CR1 |= 0x01;
        //TIM2_BKR = 0xc0;
}

STM8S103F3P6  输出 3路 PWM
