Depending on the chosen displays and 8051-derivate, it could be possible to connect the displays direct to port pins - so that would require no additional hardware! I suppose it depnds on the aim of his project, if its to use a micro to light a 7 seg display using port pins, or if its to build a scoreboard. If he has to fart around doing a port pin driven display, he wastes time on the real target. Steve |
