So I need to get 2.468 to display on a 4 Bank 7 segment display
New to this code and wiring stuff, So I am completely lost. I know I need to "BusOut" I know digit 1 is controlled by pin 1. It needs to illuminate segments a,b,g,d,e which translates to pins 14,16,15,3,5. On the display I know decimal point 1 is held by Pin 1 and pin 7 on the Display unit
How do I wire this on the bread board? How do I code this? I have looked in Youtube, I have looked through the forums I found one other question about this, but it did not help

Hi Douglas,
This is another way with BusOut but you will need to wire a lot.
BusOut Example
#include "mbed.h"
// TARGET NUCLEO F091RC
// Timer Three digits display H.MM
BusOut display_H(PC_3, PC_2, PC_0, PC_1, PB_0, PA_4, PA_1); // a, b, c, d, e, f, g
BusOut display_dM(PB_6, PA_7, PA_6, PB_11, PB_12, PA_11, PA_12); // a, b, c, d, e, f, g
BusOut display_uM(PB_13, PB_14, PB_15, PB_1, PB_2, PA_9, PA_8); // a, b, c, d, e, f, g
// Still need to define the four 7 segment digit display
DigitalOut display_DP(PD_2);
// common cathode
const int DIGITS[11] = { // G, F, E, D, C, B, A --> Invert to BusOut
0x3F, // {0111111}, // ZERO
0x06, // {0000110}, // ONE
0x5B, // {1011011}, // TWO
0x4F, // {1001111}, // THREE
0x66, // {1100110}, // FOUR
0x6D, // {1101101}, // FIVE
0x7D, // {1111101}, // SIX
0x07, // {0000111}, // SEVEN
0x7F, // {1111111}, // EIGHT
0x6F, // {1101111}, // NINE
0x00 // {00000000} // TURNIT OFF
};
int main()
{
// Turn off
display_H.write(DIGITS[10]);
display_DP = 0;
display_dM.write(DIGITS[10]);
display_uM.write(DIGITS[10]);
while (true) {
// Do something else...
// To display 2.46
display_H.write(DIGITS[2]);
display_DP = 1;
display_dM.write(DIGITS[4]);
display_uM.write(DIGITS[6]);
// still need the four 7 segment digit display for the 8
wait(1.0);
}
}
Any dude please letme know to help you
Best regards,
