How to draw colon w/ 4d 7 segment display and Max31855
Have working systems for many pottery kilns that display Max 31855 output on Adafruit display 1270.
Want to expand software by using dots and colon to indicate and up or down of temperature changes.
Got the Backpack library and GFX library, but cannot figure out how to address colons and/or dots.
Any help and advice will be appreciated.

Try the drawColon() command:
https://github.com/adafruit/Adafruit_LE ... ack.h#L390

Something like:

Code: Select all

  matrix.drawColon(true);
