SN3193呼吸灯驱动调试

首先将SN3193的enable引脚拉高
设置 04 05 06 寄存器的PWM为0xff ，亮度为最亮
ox1d 寄存器写07 ，3个LED点亮，
设置以后但是不亮，
后来对 07寄存器写0xff 就亮了，因为4， 5， 6寄存器写后没有生效，要对7寄存器写一个值进去，4 ,5, 6寄存器的值才生效，led就可以点亮了！！！！！！！！！！！！！！！

0x02 寄存器写0x20 ，呼吸功能   写0就是长亮LED功能，默认是0

static int SN3193_SetBreathTime_sled(u8 Ch, u8 T0,u8 T1,u8 T2,u8 T3,u8 T4)
{
         int ret=0;
   switch ( Ch)
   {
  case 1:
   SN3193_write_reg(0x0a,T0<<4);   //T0(time of holding off)
   SN3193_write_reg(0x10,(T1<<5)|(T2<<1)); //T1&T2(time of ramping up and hold on
   SN3193_write_reg(0x16,(T3<<5)|(T4<<1)); //T3&T4(time of ramping down and hold off)
   break;
  case 2:
   SN3193_write_reg(0x0b,T0<<4);
   SN3193_write_reg(0x11,(T1<<5)|(T2<<1));
   SN3193_write_reg(0x17,(T3<<5)|(T4<<1));
   break;
  case 3:
   SN3193_write_reg(0x0c,T0<<4);
    SN3193_write_reg(0x12,(T1<<5)|(T2<<1));
              SN3193_write_reg(0x18,(T3<<5)|(T4<<1));
   break;

  }
         return ret;
}
