CC2541PWM
//PWM初始化
void PWM_init(uint16 arr){
RGB_Callback(&PWM_DateCBs);//函数注册
P0DIR= BV(3)|BV(4)|BV(5);
//设置pwm端口为外设端口，非gpio
P0SEL= BV(3)|BV(4)|BV(5);
PERCFG = 0x03; //将UART切换到备用位置2，防止占用PWM输出
T1CTL &= 0;
T1CC0L = arr%0xFF;
T1CC0H = arr/0xFF;
//ch1
T1CC1L = 200%0xFF;
T1CC1H = 200/0xFF;
T1CCTL1 = 0x2C;
//ch2
T1CC2L = 500%0xFF;
T1CC2H = 500/0xFF;
T1CCTL2 = 0x2C;
//ch3
T1CC3L = 500%0xFF;
T1CC3H = 500/0xFF;
T1CCTL3 = 0x2C;
//star tiner1
//必须设置以下两句，否则定时器不工作， 但是我们这里只用pwm， 因此可以直接用pwm的中断， 不用t1的定时器中断， 因此不用设置
T1CCTL0 = 0x2C; // IM = 1, CMP = Clear output on compare; Mode = Compare
T1CTL = 0x02;
}
大家帮我看有没有什么问题？
