Hi friends,

I want to ask a question about display. I used display which is 7 segment and 2 digit. I want know how to use display which is 14 segment and 8 digit. To run 7 segment display, we use hexadecimal number system. Which number system will we use to run 14 segment display? If you explain connections between pic or port expander and display and give me a simple example, I will appreciate you.

Thanks

If this is a commercially available product
then give us the mfr/make/model or a link to the data sheet
else describe(show) how the display is configured.

Normally a table of 'character to bit translations' is done,grab an LCD datasheet and see the how 'they' do it.

Without further information, it's difficult to tell you exactly how to proceed.

This thread has an example of how to make the lookup table. Look for
the Digit_Map[] array:
