  1. Witam mam problem z projektem przepustnicy do gier. Pod podpięciu Arduino do komputera jako kontroler wykrywa tyko oś Z i obrót osi Z. Kontroler ma działać jako Throttle. Prosił bym o pomoc. Kod programu. #include "UnoJoy.h" void setup(){ setupPins(); setupUnoJoy(); } void loop(){ // Always be getting fresh data dataForController_t controllerData = getControllerData(); setControllerData(controllerData); } void setupPins(void){ // Set all the digital pins as inputs // with the pull-up enabled, except for the // two serial line pins for (int i = 2; i <= 12; i++){ pinMode(i, INPUT); digitalWrite(i, HIGH); } pinMode(A4, INPUT); digitalWrite(A4, HIGH); pinMode(A5, INPUT); digitalWrite(A5, HIGH); } dataForController_t getControllerData(void){ // Set up a place for our controller data // Use the getBlankDataForController() function, since // just declaring a fresh dataForController_t tends // to get you one filled with junk from other, random // values that were in those memory locations before dataForController_t controllerData = getBlankDataForController(); // Since our buttons are all held high and // pulled low when pressed, we use the "!" // operator to invert the readings from the pins controllerData.triangleOn = !digitalRead(2); controllerData.circleOn = !digitalRead(3); controllerData.squareOn = !digitalRead(4); controllerData.crossOn = !digitalRead(5); controllerData.dpadUpOn = !digitalRead(6); controllerData.dpadDownOn = !digitalRead(7); controllerData.dpadLeftOn = !digitalRead(8); controllerData.dpadRightOn = !digitalRead(9); controllerData.l1On = !digitalRead(10); controllerData.r1On = !digitalRead(11); controllerData.selectOn = !digitalRead(12); controllerData.startOn = !digitalRead(A4); controllerData.homeOn = !digitalRead(A5); // Set the analog sticks // Since analogRead(pin) returns a 10 bit value, // we need to perform a bit shift operation to // lose the 2 least significant bits and get an // 8 bit number that we can use controllerData.leftStickX = analogRead(A0) >> 2; controllerData.leftStickY = analogRead(A1) >> 2; controllerData.rightStickX = analogRead(A2) >> 2; controllerData.rightStickY = analogRead(A3) >> 2; controllerData.throttle = analogRead(A5)>>2; // And return the data! return controllerData; } oraz kod biblioteki /* UnoJoy.h * Alan Chatham - 2012 * RMIT Exertion Games Lab * * This library gives you a standard way to create Arduino code that talks * to the UnoJoy firmware in order to make native USB game controllers. * Functions: * setupUnoJoy() * getBlankDataForController() * setControllerData(dataForController_t dataToSet) * * NOTE: You cannot use pins 0 or 1 if you use this code - they are used by the serial communication. * Also, the setupUnoJoy() function starts the serial port at 38400, so if you're using * the serial port to debug and it's not working, this may be your problem. * * === How to use this library === * If you want, you can move this file into your Arduino/Libraries folder, then use it like a normal library. * However, since you'll need to refer to the details of the dataForController_t struct in this file, I would suggest you use * it by adding it to your Arduino sketch manually (in Arduino, go to Sketch->Add file...) * * To use this library to make a controller, you'll need to do 3 things: * Call setupUnoJoy(); in the setup() block * Create and populate a dataForController_t type variable and fill it with your data * The getBlankDataForController() function is good for that. * Call setControllerData(yourData); where yourData is the variable from above, * somewhere in your loop(), once you're ready to push your controller data to the system. * If you forget to call sendControllerData in your loop, your controller won't ever do anything * * You can then debug the controller with the included Processing sketch, UnoJoyProcessingVisualizer * * To turn it into an actual USB video game controller, you'll reflash the * Arduino's communication's chip using the instructions found in the 'Firmware' folder, * then unplug and re-plug in the Arduino. * * Details about the dataForController_t type are below, but in order to create and use it, * you'll declare it like: * * dataForController_t sexyControllerData; * * and then control button presses and analog stick movement with statements like: * * sexyControllerData.triangleOn = 1; // Marks the triangle button as pressed * sexyControllerData.squareOn = 0; // Marks the square button as unpressed * sexyControllerData.leftStickX = 90; // Analog stick values can range from 0 - 255 */ #ifndef UNOJOY_H #define UNOJOY_H #include <stdint.h> #include <util/atomic.h> #include <Arduino.h> // This struct is the core of the library. // You'll create an instance of this and manipulate it, // then use the setControllerData function to send that data out. // Don't change this - the order of the fields is important for // the communication between the Arduino and it's communications chip. typedef struct dataForController_t { uint8_t triangleOn : 1; // Each of these member variables uint8_t circleOn : 1; // control if a button is off or on uint8_t squareOn : 1; // For the buttons, uint8_t crossOn : 1; // 0 is off uint8_t l1On : 1; // 1 is on uint8_t l2On : 1; uint8_t l3On : 1; // The : 1 here just tells the compiler uint8_t r1On : 1; // to only have 1 bit for each variable. // This saves a lot of space for our type!

  2. Dziękuje na pewno sprawdzę, a jaką antenę musiał bym do nich dobrać?
  3. Witam mam problem z wybraniem modułów radiowych do mojego projektu. Moduły mają przesyłać stan przycisku oraz wiadomość do wyświetlacza LCD, odległość między niemi nie zawsze będzie sama ale nie będzie przekraczała 1km oraz będzie między nimi przewyższenie. Tu nasuwa się drugie pytanie czy muszę użyć 2 arduino? Projekt to stoper odpalany przyciskiem w jednym miejscu (startu) oraz fotokomórki (mety). Potrzebuję przesłać stan przycisku i informacje diodą o możliwości startu(opcjonalnie LCD tak jak napisałem powyżej). Proszę o pomoc w wyborze osoby które się na tym znają, ja znalazłem moduł HC-12 SI4463 433MHz - 1000m.
  4. Dane były wyświetlane poglądowo. obecna wersja kodu wyświetla je na lcd Teraz rodzi się drugie pytanie jakich modułów radiowych użyć odległość między nimi raczej nie będzie przekraczać jednego kilometra lecz będzie miedzy nimi przewyższenie oraz czy murze użyć 2 arduino? To jest nowa wersja kodu trochę napisana samemu a trochę przekopiowana z internetu. #include <LCD.h> #include <LiquidCrystal.h> #include <LiquidCrystal_I2C.h> #include <Wire.h> LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); void setup() { lcd.begin(16, 2); lcd.clear(); Serial.begin(9600); pinMode(7, INPUT); digitalWrite(7, HIGH);//8 pinMode(2, INPUT); digitalWrite(2, HIGH);//9 } double i = 0; double a = millis(); double c ; void loop() { lcd.clear(); lcd.print("press start"); delay(100); if(digitalRead(7) == LOW) { lcd.clear(); a = millis(); while(digitalRead(2) == HIGH) { c = millis(); i = (c - a) / 1000; lcd.print(i); lcd.setCursor(7,0); lcd.print("Sec's"); lcd.setCursor(0,0); Serial.println(c); Serial.println(a); Serial.println(i); Serial.println("......"); delay(100); } if(digitalRead(2) == LOW) { while(digitalRead(7) == HIGH) { lcd.setCursor(0,0); lcd.print(i); lcd.setCursor(11,0); lcd.print(""); lcd.setCursor(0,0); delay(100); } } } }
  5. Miał być to przełącznik do włączania kodu ale po usunięciu całej pętli jest to samo co opisałem powyżej.
  6. Witam mam problem z jednym z moich projektów chciał bym uzyskać stoper który po wciśnięciu przycisku zaczyna odmierzać czas oraz po przecięciu fotokomórki następuje zatrzymuje wyświetla oraz możliwość nowego pomiaru(od zera). Na razie zamiast fotokomórki jest przycisk oraz roboczo wyświetlam wyniki na serial porcie. unsigned long tstart = 0; int buttons=7;//przycisk start int buttonsto=2;// przycist stop docelowo fotokomorka void setup() { pinMode(buttons, INPUT_PULLUP); pinMode(buttonsto, INPUT_PULLUP); Serial.begin(9600); } void loop() { while(digitalRead(4)==LOW) { if (digitalRead(buttons) == LOW) { tstart=millis(); } if (digitalRead(buttonsto) == LOW) { Serial.println(millis()-tstart); } } } Prosił bym o pomoc bo średnio wiem jak się do tego zabrać, obecnie wyświetla czas ale tylko raz po restarcie arduino i go wyświetla
  7. Witam serdecznie mam problem z poprawną pracą wyświetlacza po podłączeniu go do arduino UNO i wgraniu programu z przykładowych oraz jego skonfigurowaniu pojawiło się na wyświetlaczu 16 prostokątów. Niem co mam z tym robić bardzo proszę o jakieś naprowadzenie na naprawę tego błędu. PS.Jestem dopiero początkującym.
