摘要：
1、使用TIM3_CC1，相关联引脚P1_7#define GPIOPWM() do{P1SEL |= 0x80;}while(0);#define GPIOCLOSEPWM() do{P1SEL &= ~0x80; P1_7 = 0;}while(0);void GPIOInit(void){ P1SEL &= ~0x80; P1DIR |= 0x80; P1_7 = 0;}void timer3Init(void)//产生PWM{ PERCFG |= 0x20;//选择定时器3的备用位置2 P2SEL |= 0x20;//设置定时器3优先 T3CCTL1 = 0; ... 阅读全文
