上面的代码里哪个引脚输出通道1的pwm波

在这段代码中，引脚PA6对应的通道TIM3_CH1输出PWM波：

TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_Pulse = CCR1_Val;
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;

TIM_OC1Init(TIM3, &TIM_OCInitStructure);

TIM_CCxCmd(TIM3, TIM_Channel_1, TIM_CCx_Enable);

其中，`TIM_OC1Init(TIM3, &TIM_OCInitStructure)`初始化了TIM3通道1的PWM输出，`TIM_CCxCmd(TIM3, TIM_Channel_1, TIM_CCx_Enable)`使能了TIM3通道1的PWM输出。

请帮我使用GD32F103RBT6 生成一份 PC6引脚 定时器2通道0 PWM波 驱动代码

要使用GD32F103RBT6微控制器的PC6引脚生成定时器2通道0的PWM波形，你需要编写一段代码来配置定时器和相关GPIO。以下是一个简化的代码示例，假设你使用的是标准外设库函数。

#include "gd32f10x.h"

void rcu_config(void) {
    // 使能GPIOC和TIMER2的时钟
    rcu_periph_clock_enable(RCU_GPIOC);
    rcu_periph_clock_enable(RCU_TIMER2);
}

void gpio_config(void) {
    // 将PC6引脚配置为复用推挽输出
    gpio_mode_set(GPIOC, GPIO_MODE_AF, GPIO_PUPD_NONE, GPIO_PIN_6);
    gpio_output_options_set(GPIOC, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_6);
    // 将PC6引脚复用为TIMER2通道0
    gpioAF_config(GPIOC, GPIO_AF_1, GPIO_PIN_6);
}

void timer_config(void) {
    // 定时器2初始化设置
    timer_oc_parameter_struct timer_ocinit;
    timer_parameter_struct timer_initpara;

    // 定时器基本配置
    timer_deinit(TIMER2);
    timer_struct_para_init(&timer_initpara);
    timer_initpara.prescaler         = 7199; // 预分频器值
    timer_initpara.alignedmode       = TIMER_COUNTER_EDGE;
    timer_initpara.counterdirection   = TIMER_COUNTER_UP;
    timer_initpara.period            = 999;  // 自动重装载值
    timer_initpara.clockdivision      = TIMER_CKDIV_DIV1;
    timer_init(TIMER2, &timer_initpara);

    // 定时器通道0 PWM模式配置
    timer_channel_output_struct_para_init(&timer_ocinit);
    timer_ocinit.outputstate  = TIMER_CCX_ENABLE;
    timer_ocinit.ocpolarity   = TIMER_OC_POLARITY_HIGH;
    timer_ocinit.ocidlestate  = TIMER_OC_IDLE_STATE_LOW;
    // 设置比较模式为PWM模式1
    timer_ocinit.ocmode       = TIMER_OC_MODE_PWM0;
    timer_ocinit.pulse        = 499;  // 设置PWM占空比
    timer_channel_output_config(TIMER2, TIMER_CH_0, &timer_ocinit);

    // 使能定时器2
    timer_enable(TIMER2);
}

int main(void) {
    // 系统时钟配置
    rcu_config();
    // GPIO配置
    gpio_config();
    // 定时器配置
    timer_config();

    while (1) {
        // 主循环
    }
}

这段代码是一个基础的示例，展示了如何配置GD32F103RBT6的PC6引脚作为定时器2通道0的PWM输出。你需要根据自己的实际需求调整预分频器值、自动重装载值以及脉冲值来达到期望的PWM频率和占空比。

请注意，以上代码仅供参考，实际使用时可能需要根据具体的库函数版本和硬件连接情况进行调整。务必参考GD32F103的参考手册和库函数手册来编写适合你硬件和软件环境的代码。

stm32多通道输出pwm波

在STM32中，可以使用定时器来生成PWM波。下面是一个多通道输出PWM波的示例代码：

#include "stm32f10x.h"

void TIM2_PWM_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_OCInitTypeDef TIM_OCInitStructure;
    
    //使能GPIO和TIM2的时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);
    
    //配置GPIO为复用功能，推挽输出
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_2 | GPIO_Pin_3;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
    
    //TIM2的基本配置
    TIM_TimeBaseStructure.TIM_Period = 999;  //计数器周期为1000
    TIM_TimeBaseStructure.TIM_Prescaler = 71;  //预分频器为72
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);
    
    //通道1 PWM模式配置
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = 499;  //占空比50%
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC1Init(TIM2, &TIM_OCInitStructure);
    
    //通道2 PWM模式配置
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = 249;  //占空比25%
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC2Init(TIM2, &TIM_OCInitStructure);
    
    //通道3 PWM模式配置
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = 749;  //占空比75%
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC3Init(TIM2, &TIM_OCInitStructure);
    
    //通道4 PWM模式配置
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = 99;  //占空比10%
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC4Init(TIM2, &TIM_OCInitStructure);
    
    //启动TIM2
    TIM_Cmd(TIM2, ENABLE);
}

说明：

1. 使用了TIM2定时器，并且将GPIOA的0、1、2、3引脚配置为复用功能，推挽输出。
2. TIM2的时钟频率为72MHz，通过预分频器设置为1MHz，计数器周期设置为1000，即每1ms计数一次。
3. 通道1、2、3、4都使用了PWM模式，占空比分别为50%、25%、75%、10%。

在上面的例子中，通过修改TIM_OCInitStructure的TIM_Pulse成员可以控制占空比的大小，从而实现多通道输出不同占空比的PWM波。
