Okay see what we have inside
Seven Segment display is how we see the numbers in modern day electronics. Digits are displayed with the help of 7 bars out of which 4 are vertical and 3 are horizaontal. Decimal point can also be displayed with this display by turning it on/off. 7 Segment display is used as it is easy to operate upon. We can display digits from 0 to 9, decimal point and alphabets from A to F too.
-This function is the only one we need to call. We need to tell the pin numbers of datapin, clockpin,latchpin, true/false whether decimal is on/off, true/false if common anode is used/not used and the value to be displayed respectively in the arguments. -Here in example, I assumed datapin number =4, clockpin number=7, latchpin number =8 with decimal point on and display using common anode on. The number 2 wil be displayed on the 7 segment display.
This is a function used internally for the passing out value to right pins.
This is a function used internally for coordinating the different functions for output.
This is used to convert interger to bit system which will then be interpreted one-by-one for on/off different segments of 7-segments display.
Returns the Pin in response to the pin number passed.
