7 SEGMENT DISPLAY
|
||||||
|
|
||||||
|
segment.s implements the logic behind displaying numbers between 0 and 9 on
|
||||||
|
a 7 segment display. The PIN configuration is the following:
|
||||||
|
|
||||||
|
* a - DIGITAL PIN 0
|
||||||
|
* b - DIGITAL PIN 1
|
||||||
|
* c - DIGITAL PIN 2
|
||||||
|
* d - DIGITAL PIN 3
|
||||||
|
* e - DIGITAL PIN 4
|
||||||
|
* f - DIGITAL PIN 5
|
||||||
|
* d - DIGITAL PIN 6
|
||||||
|
|
||||||
|
All these PINs are connected on PORTD, so we need to keep that in mind when
|
||||||
|
writing our output to the correct PORT.
|
||||||
|
|
||||||
|
The boolean formulas used to configure the PINs are calcualted using
|
||||||
|
Karnaugh Diagrams.
|
||||||
|
|
||||||
|
As a final word, don't forget to add resistors in series with each display
|
||||||
|
PIN, on the breadboard, because I forgot to do so and I completely screwed
|
||||||
|
a display.
