Driver code for 14 segment LED display

Anyone know where I can obtain a routine to convert ASCII code into code to drive 14 segment LED display. Thank you.

we need a few more info. In fact you can find almost everything everywhere but..

what type of hardware you want to use.

• 1. one PIC with all the i/o you need
  2. one 8 pins PIC with external stuff like shift register
  3. ???

is the ASCII come by serial, parrallel, by phone, by mental thought or else ?

what kind of display you want : bargraph, 7 segments (multiplex or not)

tell us we can certainely help you

Steve:

Thanks for your prompt reply.

I need to program a 18F6720 to directly drive a Fairchild MDA6410
14 Segment LED display using PICbasic. I can get units that accept 2 bytes in hex in serial form but this will be a large volume application and external part count in of extreme impotance.

I would appreaciate any suggestions.

Thanks
Durward

All hardware you need

• 1. 17 i/o pin (2 will be connected to transistor/mosfet to drive Common anode of each display)
  2. few resistors (depending on how you want to do it, some like to use 1 by common anode or 1 by digit segment)

for the software

• 1. you must create a table to convert each number/character you want to display as output pin pattern on your PIC...store them into internal EEPROM or in a array... you'll need about 16 character x 2 (8bits + 6bits (we forget about decimal point)) so 32 EEPROM location or array of 32 elements.

Since you'll do kinda multiplex display, I suggest to use internal timer to toggle from the first to the second display. Should be fast enough to avoid display blinking.

how does it sound to you?

Thanks again Steve for the futher info.
