GD32f150写一个PWM输出程序

好的，以下是一个简单的GD32f150 PWM输出程序的示例代码：

#include "gd32f1x0.h"

void pwm_init(void)
{
    /* 使能GPIO时钟 */
    rcu_periph_clock_enable(RCU_GPIOA);

    /* 配置PA1为复用输出模式 */
    gpio_mode_set(GPIOA, GPIO_MODE_AF_PP, GPIO_PUPD_NONE, GPIO_PIN_1);
    gpio_output_options_set(GPIOA, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_1);

    /* 使能TIMER时钟 */
    rcu_periph_clock_enable(RCU_TIMER1);

    /* 配置TIMER1为PWM模式 */
    timer_oc_parameter_struct timer_ocinitpara;
    timer_parameter_struct timer_initpara;

    timer_deinit(TIMER1);

    timer_struct_para_init(&timer_initpara);
    timer_initpara.prescaler         = 0; /* 不分频 */
    timer_initpara.alignedmode       = TIMER_COUNTER_EDGE;
    timer_initpara.counterdirection  = TIMER_COUNTER_UP;
    timer_initpara.period            = 1000; /* PWM周期为1ms */
    timer_initpara.clockdivision     = TIMER_CKDIV_DIV1;
    timer_init(TIMER1, &timer_initpara);

    timer_oc_struct_para_init(&timer_ocinitpara);
    timer_ocinitpara.ocpolarity       = TIMER_OC_POLARITY_HIGH;
    timer_ocinitpara.outputstate      = TIMER_CCX_ENABLE;
    timer_ocinitpara.ocidlestate      = TIMER_OC_IDLE_STATE_LOW;
    timer_ocinitpara.compare          = 500; /* PWM占空比为50% */
    timer_channel_output_config(TIMER1, TIMER_CH_1, &timer_ocinitpara);

    timer_auto_reload_shadow_enable(TIMER1);
    timer_enable(TIMER1);
}

int main(void)
{
    pwm_init();

    while (1) {
        /* 程序主循环 */
    }

    return 0;
}

这个程序使用TIMER1的CH1通道输出PWM信号，占空比为50%，周期为1ms。你可以根据需要修改占空比和周期。
