Hey there!
To enable colon in this display we use
tm1637.pint(POINT_ON);
but is it possible to turn on only one dot of this colon?
Regards!
Hi,
It depends on the exact display you have and how it is connected to the tm1637 driver chip. BUT chances are the display has two leds (one for each dot) wired together internally, or the same single led lights both dots from behind, so you won't be able to control them individually.
