A program to demonstrate the BusOut function to display digits on a 7-segment display with a common cathode. It displays digits 0, 1, 2, 3 in turn.
Please see schematic below for further details.
Schematic for example 03-05
/*Program Example 3.5: Simple demonstration of 7-segment display. Display digits 0, 1, 2, 3 in turn.
*/
#include "mbed.h"
BusOut display(D0,D1,D2,D3,D4,D5,D6,D7); // segments a,b,c,d,e,f,g,dp
int main()
{
while(1) {
for(int i=0; i<4; i++) {
switch (i) {
case 0:
display = 0x3F;
break; //display 0
case 1:
display = 0x06;
break; //display 1
case 2:
display = 0x5B;
break;
case 3:
display = 0x4F;
break;
} //end of switch
wait(0.2);
} //end of for
} //end of while
}
The following image shows the built circuit.
