I need to get the last octet of an IP address into 3 separate int
s to control a MAX7219.
I know the octet is an uint8_t
Using IPAddress ip = Wifi.localIP();
, say my ip[3] was 148, I need:
int b1 = 1
int b2 = 4
int b3 = 8
but say ip[3] was only 8, then b1 and b2 have to be 0.
First thing that came to mind; there are probably more elegant ways to do this, but it works:
b3 = ip[3] % 10;
b2 = ((ip[3] % 100) - b3) / 10;
b1 = (ip[3] - (10 * b2) - b3) / 100;
I don't know why you would need separate integers, though.
