7 Seg Display Letters? - CH3NO2 - 02-14-2021

Hello, is it possible to make the 7 segment display on the IO element shield display letters? Obviously not all letters are possible by the 7 segment design, but those that are, is that possible?

If so, how would I go about learning to do this? It would be especially useful for one of my projects.

Thank you

Yes this is of course possible! You can make it show whatever you want. Read through the IO element tutorial here

Basically, you would need to change the module called "seven_seg" in that tutorial which is a look-up table that contains what digits turn on for what number. You would need to modify it to map letters to their segment representation.
