Question

zigbee怎么在协议栈里输出pwm波

Answer 1

void Timer1Pwm_init(void)
{
PERCFG &= ~0x40; // Select Timer 1 Alternative 0 location
P2DIR = (P2DIR & ~0xC0) | 0x80; // Give priority to Timer 1
P0SEL |= 0x08; // Set P0_3 to peripheral

T1CC0L = 0xff; // PWM signal period
T1CC0H = 0x7f;

T1CC1L = 0x78; // PWM duty cycle
T1CC1H = 0x10;

T1CCTL1 = 0x1c;

T1CTL |= 0x0f; // divide with 128 and to do i up-down mode
return ;
}
void start_pwm(void)
{

Timer1Pwm_init();

return ;
}
