Request the addition of 3 new characters #23

Closed thegreenalien closed 6 years ago

thegreenalien commented 6 years ago

Could you please add inverted 4, inverted 6, inverted 7 and inverted 9 to the character list - this would then allow a complete inverted number display for use in head-up displays, where the LED numbers are reflected off the vehicle windscreen.

At present, 1 inverts to itself, 2 inverts to 5, 3 inverts to itself, 5 inverts to 2, 8 inverts to itself, and 0 inverts to itself, so you can see what's missing.

For inverted 4, light segments B,C,E & G For inverted 6, light segments A,B,D,E,F & G For inverted 7, light segments B,C & D For inverted 9, light segments A,B,C,D,E & G

TIA

Realised that this won't work as decimal point won't invert, so will have to build display with inverted 7 segment led modules.

My previous comment was wrong. I have reopened this issue. Definitely need these 4 new characters. 3 inverted is E!

Going to close this issue and rewrite it.
