I am about to connect three 7-segment LEDs to a 16F88. I am worried that the maximum absolute reverse voltage allowed on the segments is 3.3V.
Does the GCBasic routine connect the cathodes to positive to turn off a display element? In which case I could be exceeding the 3.3V, or does it make the cathode pin an input to turn off the display (which should be ok).
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Excuse my stupidity. I will of course need to use a transistor on the cathode because of the current (from up to 7 segments).
