 ===== Software Design =====
-<note tip>
 For this project, the following resources of the microcontroller were used:
 • 1 general-purpose pin set as an output for an LED (PD6)
 • 1 general-purpose pin set as an input for a button (PD5)
 • Alphanumeric LCD display with HD44780 driver configured on port C
 • 16 pins used as IN/OUT for cable continuity testing
 The testing program uses 1 port with 8 bits for signal transmission and another port for reception, utilizing PORTA and PORTB, one defined as an input and the other as an output.
 Two arrays are used to store the display sequences for individual LED display or continuous display. For continuity testing, the individual display sequence is used, and the received result at the reception port is stored in the reception[8] array, thus preserving the order in which the test signal was received. By comparing the reception[8] array with three other arrays storing the correct sequences, the type of cable tested (crossover, rollover, straight) can be determined. If none of these patterns match, the cable is declared defective. The display of the detected cable type is done through an LCD display along with a map indicating the defective or good wires.
-for(i=0;i<=7;i++){ // iterate through each bit of the test port and turn it on
+      for(i=0;i<=7;i++){ // iterate through each bit of the test port and turn it on
-PORTA = afisare_single[i];
+      PORTA = afisare_single[i];
-}
+      }
 This code snippet activates the pins on the test port. The logical signal 1 will pass through the cable and reach the reception port. Depending on the order in which it arrives, the values will be stored in an array to identify the type of cable.
-if(PINB > 0) {  // if something is detected at input on port B
+    if(PINB > 0) {  // if something is detected at input on port B
     if(IN1 == 1) receptie[i] = 1;   // write the corresponding value for the detected pin
     else if(IN2 == 1) receptie[i] = 2;

     else if(IN7 == 1) receptie[i] = 7;
     else if(IN8 == 1) receptie[i] = 8;
-}  // end if detection
+    }  // end if detection
 The received values are stored in the receptie[] array, preserving the order of each measured pin number. This array can be directly used to display the values on the LCD screen.
-if(receptie[i] == straight[i]) sum++;
+    if(receptie[i] == straight[i]) sum++;
-if(sum == 8) {   // if all 8 wires are connected
+    if(sum == 8) {   // if all 8 wires are connected
     lcd_puts("Defect   ");
     for(i=0;i<=7;i++){     // print the reception vector

         lcd_puts(buffer);
     }

+    }
 The checking for each type of cable is done by testing each value in the received vector. If all 8 values are correct, it means that all wires are good and the respective configuration has been detected. If not all values are correct, another configuration is tested, and if no cable is identified, it will be declared defective. For a defective cable, the detected order is still displayed to identify the interrupted wires.

 Resistors R1-R8 maintain the input potential at logical low (0) in case the wire is interrupted. Otherwise, the measured potential could be affected by external disturbances or user handling, etc. The resistor values are not critical and were selected to consume as little current as possible from the microcontroller's pins, resulting in a current of 60uA for an 82k resistor.
