Hello There...
First, please watch my code..

}

if (i > 7) return;
Wire.beginTransmission(TCAADDR);
Wire.write(1 << i);
Wire.endTransmission();
}
void helle(uint8_t i) {
if (i > 7) return;
Wire.beginTransmission(hellee);
Wire.write(1 << i);
Wire.endTransmission();
}

I have 2 trouble about this code..
First,When I run this code, only tcaselect(7) show a result and others are all 0. So I change tcaselect(7)
to tcaselect(4) and then run, the tcaselect(4) change tcaselect(5) until 7 and then Finally I get full of the data.... How horrible.. When I reboot my computers power, (That mean next day or something..)
I Do the same thing for about 7 minute. I just want the data at first running So Could you solve my problem?
And second, I mention 'helle' is second tca9548 chip but when I run the code, tcaselect(7) and helle(2) value was same. Maybe it would be combined.. So When I eliminate helle then tcaselect(7) value going to normal.. What sould I do
