TIM_CCxCmd(TIM1, TIM_Channel_3, TIM_CCx_Disable);
This is a function call that disables the capture/compare functionality of channel 3 of TIM1.
In other words, it turns off the ability for TIM1 to capture input signals or generate output signals on channel 3. This could be used, for example, if you no longer need to capture or generate signals on that channel, or if you want to reconfigure the channel for a different purpose.
The function call takes three arguments:
1. TIM1: This specifies which timer peripheral to use (in this case, Timer 1).
2. TIM_Channel_3: This specifies which channel of the timer to disable.
3. TIM_CCx_Disable: This is a predefined constant that tells the function to disable the capture/compare functionality of the specified channel.
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:
```c
#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。
