I did make it a new library as the current lib is good as it is. I got it running last night using a timer interrupt switching 3 displays.
I have it set at 100hz switching at the moment, but the user may choose another freq if they desire. I'll test other freq. It's quite nice as i need a tiny display for a 3 digit high temp thermometer.

Multiplexing is time dependent by the application you run. The simplest way is to sweep the anode/cathode and keep them powered for about 1...3mS (depends if it's normal or superbright display and the current you supply for it) One quick and dirty example using delay library is here: (the source at the end of the paper): https://www.researchgate.net/publication/266860236_Increasing_the_efficiency_of_IO_usage_in_small_embedded_systems However, in time dependent applications (like frequency measurements around 50MHz) using software delay for digit display is a waste of time, so the library should look different. good luck, Vasile [https://ipmcdn.avast.com/images/icons/icon-envelope-tick-round-orange-animated-no-repeat-v1.gif]<https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com<https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> On Wed, Aug 30, 2017 at 3:56 AM, Matthew Schinkel <[email protected]<mailto:[email protected]>> wrote: I guess I didn't look close enough. The library does support anode displays. Anyways, I'm working on a multiplexer lib so I may run more then one segment.

I'll be adding support for anode displays by adding a user constant, and inverting the output of seven_from_digit() procedure.
