Problem with TM1637Display.h setting the colon.

Hi group,

I have got a problem with setting the colon on a TM1637Display.

I can set the colon with that code:

// set ":" between segments 2&3.
byte segto;
int value = 1244;
segto = 0x80 | display.encodeDigit((value / 100) % 10);
display.setSegments(&segto, 1, 1);

The problem is that it is overwritten with the next commands:
display.showNumberDec(A0dB / 10, false, 2, 0);
display.showNumberDec(A1dB / 10, false, 2, 2);

Do you know a way to write on the display without resetting the colon?

I have found that code which is not accepted by my library:
display.setColon(true)

With which library would that work?

Thank your for your advice.
Laszlo
