Stap 4: De Code
So... Ik ben met inbegrip van mijn code, maar ik ben niet uitleggen it... en ja ik weet dat er geen reacties... hebt u vragen, voel je vrij om te vragen, maar ik niet deed dit zodat een programmering tutorial.
Eerst moet u op te nemen van de "pitches.h"... maar te kunnen opnemen, moet u om het te krijgen vanaf hier... Toon van de Arduino Tutorial
#include "pitches.h"
Vervolgens laten we definiëren sommige reeksen om te helpen ons later wanneer moeten we gebruik van de 8 cijfers 7 segmenten weergeven
// array to activate particular digit on the 8x7segment module<br>// it is the common anode of 7 segment byte digit[8] = { 0b10000000, //digit 1 from right 0b01000000, //digit 2 from right 0b00100000, //digit 3 from right 0b00010000, //digit 4 from right 0b00001000, //digit 5 from right 0b00000100, //digit 6 from right 0b00000010, //digit 7 from right 0b00000001 //digit 8 from right }; //array for decimal number, it is the cathode, please refer to the datasheet. //therefore a logic low will activete the particular segment //PGFEDCBA, segment on 7 segment, P is the dot byte number[12] = { 0b11000000, // 0 0b11111001, // 1 0b10100100, // 2 0b10110000, // 3 0b10011001, // 4 0b10010010, // 5 0b10000010, // 6 0b11111000, // 7 0b10000000, // 8 0b10010000, // 9 0b01111111, //dot 0b11111111 //blank }; We moeten ook sommige constanten die zal ons helpen identificeren input en output pinnen verderop in de code definiëren
const int blueLEDPin = 12; const int greenLEDPin = 11; const int redLEDPin = 10; const int yellowLEDPin = 9; const int teamPinDiff = 5; //to help with computations later< const int blueButton = 17; const int greenButton = 16; const int redButton = 15; const int yellowButton = 14; const int acceptButton = 18; const int refuseButton = 19; const int speakerPin = 8; const int latchPin = 7; //connect to RCK of 8x7segment module const int clockPin = 6; //connect to SCK of 8x7segment module const int dataPin = 5; //connect to DIO of 8x7segment module const int multiplexDelay = 1; const int dotNumber = 10; const int blankNumber = 11;
We moeten ook blijven sommige variabelen om te weten wat er gaande is in het programma
int currentTeam = 0; int blueScore = 0; int greenScore = 0; int redScore = 0; int yellowScore = 0;byte blueDigit1 = number[blankNumber]; byte blueDigit2 = number[0]; byte greenDigit1 = number[blankNumber]; byte greenDigit2 = number[0]; byte redDigit1 = number[blankNumber]; byte redDigit2 = number[0]; byte yellowDigit1 = number[blankNumber]; byte yellowDigit2 = number[0];
Dan instellen we de pin-modi en de weergave
void setup() { pinMode(blueLEDPin, OUTPUT); pinMode(greenLEDPin, OUTPUT); pinMode(redLEDPin, OUTPUT); pinMode(yellowLEDPin, OUTPUT); pinMode(blueButton, INPUT); pinMode(greenButton, INPUT); pinMode(redButton, INPUT); pinMode(yellowButton, INPUT); pinMode(acceptButton, INPUT); pinMode(refuseButton, INPUT); pinMode(speakerPin, OUTPUT); digitalWrite(blueLEDPin, LOW); digitalWrite(greenLEDPin, LOW); digitalWrite(redLEDPin, LOW); digitalWrite(yellowLEDPin, LOW); pinMode(latchPin, OUTPUT); pinMode(clockPin, OUTPUT); pinMode(dataPin, OUTPUT); digitalWrite(latchPin, HIGH); } En we maken de lus-functie die wordt uitgevoerd nadat Setup is voltooid
void loop() { ProgramLoop(); WriteScore(); } Zoals u ziet, ik heb gemaakt, functies om te scheiden van mijn code een beetje beter... dus laten we deze functies maken
void ProgramLoop() { if (currentTeam == 0) { if (digitalRead(blueButton) == HIGH) { currentTeam = blueLEDPin; PlayAnswerBlue(); } else if (digitalRead(greenButton) == HIGH) { currentTeam = greenLEDPin; PlayAnswerGreen(); } else if (digitalRead(redButton) == HIGH) { currentTeam = redLEDPin; PlayAnswerRed(); } else if (digitalRead(yellowButton) == HIGH) { currentTeam = yellowLEDPin; PlayAnswerYellow(); } } else { digitalWrite(currentTeam, HIGH); if (digitalRead(currentTeam + teamPinDiff) == LOW) { if (digitalRead(acceptButton) == HIGH) { PlayAccept(); IncrementScore(); } else if (digitalRead(refuseButton) == HIGH) { PlayDeny(); ResetState(); } } } } void ResetState() { currentTeam = 0; digitalWrite(blueLEDPin, LOW); digitalWrite(greenLEDPin, LOW); digitalWrite(redLEDPin, LOW); digitalWrite(yellowLEDPin, LOW); } void IncrementScore() { switch (currentTeam) { case blueLEDPin: blueScore++; if (blueScore > 9) { if (blueScore > 99) { blueScore = 0; } blueDigit1 = number[blueScore / 10]; } blueDigit2 = number[blueScore % 10]; break; case greenLEDPin: greenScore++; if (greenScore > 9) { if (greenScore > 99) { greenScore = 0; } greenDigit1 = number[greenScore / 10]; } greenDigit2 = number[greenScore % 10]; break; case redLEDPin: redScore++; if (redScore > 9) { if (redScore > 99) { redScore = 0; } redDigit1 = number[redScore / 10]; } redDigit2 = number[redScore % 10]; break; case yellowLEDPin: yellowScore++; if (yellowScore > 9) { if (yellowScore > 99) { yellowScore = 0; } yellowDigit1 = number[yellowScore / 10]; } yellowDigit2 = number[yellowScore % 10]; break; } ResetState(); } void WriteScore() { display8x7segment(digit[0], number[dotNumber]); display8x7segment(digit[0], blueDigit2); display8x7segment(digit[1], blueDigit1); display8x7segment(digit[2], number[dotNumber]); display8x7segment(digit[2], greenDigit2); display8x7segment(digit[3], greenDigit1); display8x7segment(digit[4], number[dotNumber]); display8x7segment(digit[4], redDigit2); display8x7segment(digit[5], redDigit1); display8x7segment(digit[6], number[dotNumber]); display8x7segment(digit[6], yellowDigit2); display8x7segment(digit[7], yellowDigit1); } void display8x7segment(byte digit, byte number) { digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, digit); // clears the right display shiftOut(dataPin, clockPin, MSBFIRST, number); // clears the left display digitalWrite(latchPin, HIGH); delay(1); } void PlayAnswerBlue() { display8x7segment(digit[7], number[blankNumber]); beep(speakerPin, NOTE_C5, 100); delay(25); beep(speakerPin, NOTE_C5, 100); delay(25); beep(speakerPin, NOTE_C5, 100); } void PlayAnswerGreen() { display8x7segment(digit[7], number[blankNumber]); beep(speakerPin, NOTE_D5, 100); delay(25); beep(speakerPin, NOTE_D5, 100); delay(25); beep(speakerPin, NOTE_D5, 100); } void PlayAnswerRed() { display8x7segment(digit[7], number[blankNumber]); beep(speakerPin, NOTE_E5, 100); delay(25); beep(speakerPin, NOTE_E5, 100); delay(25); beep(speakerPin, NOTE_E5, 100); } void PlayAnswerYellow() { display8x7segment(digit[7], number[blankNumber]); beep(speakerPin, NOTE_F5, 100); delay(25); beep(speakerPin, NOTE_F5, 100); delay(25); beep(speakerPin, NOTE_F5, 100); } void PlayAccept() { display8x7segment(digit[7], number[blankNumber]); beep(speakerPin, NOTE_C5, 75); delay(10); beep(speakerPin, NOTE_D5, 75); delay(10); beep(speakerPin, NOTE_E5, 75); delay(10); beep(speakerPin, NOTE_G5, 75); delay(10); beep(speakerPin, NOTE_E5, 75); delay(10); beep(speakerPin, NOTE_G5, 75); delay(10); beep(speakerPin, NOTE_C6, 75); } void PlayDeny() { display8x7segment(digit[7], number[blankNumber]); beep(speakerPin, NOTE_A4, 1000); } void beep (unsigned char speakerPin, int frequencyInHertz, long timeInMilliseconds) { int x; long delayAmount = (long)(1000000/frequencyInHertz); long loopTime = (long)((timeInMilliseconds*1000)/(delayAmount*2)); for (x=0; x < loopTime; x++) { digitalWrite(speakerPin, HIGH); delayMicroseconds(delayAmount); digitalWrite(speakerPin, LOW); delayMicroseconds(delayAmount); } }
