Hi,
I would like to build a customizable node (customizable by the controller) wich can detect presence for a certain distance.
The node comportement is good...- Is it good practice to do a sketch like this ?
- "gw.request(CHILD_ID_SONAR_MIN_RANGE, V_DISTANCE);", response is provided by the controller ?
- Can i store my minimum range distance in EEPROM ? or is it better to do a "gw.request" ?
#include <SPI.h> #include <MySensor.h> #include <NewPing.h> #define TRIGGER_PIN 6 // Arduino pin tied to trigger pin on the ultrasonic sensor. #define ECHO_PIN 5 // Arduino pin tied to echo pin on the ultrasonic sensor. /** Default value **/ #define MAX_DISTANCE 300 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm. unsigned long SLEEP_TIME = 5000; // Sleep time between reads (in milliseconds) // NRFRF24L01 radio driver (set low transmit power by default) MyTransportNRF24 radio(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW); //MyTransportRFM69 radio; // Message signing driver (none default) //MySigningNone signer; // Select AtMega328 hardware profile MyHwATMega328 hw; // Construct MySensors library MySensor gw(radio, hw); // Id of the sensor child #define CHILD_ID_SONAR 0 #define CHILD_ID_SONAR_MIN_RANGE 1 //Setting default min / max range default value int minRange = 50; boolean inRange = false; boolean outRange = false; NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance. MyMessage SonarMessage(CHILD_ID_SONAR, V_DISTANCE); unsigned long lastSend; // the timeStamp you use to constantly check vs the current time (millis() returns an unsigned long timestamp) unsigned long IntervalBetweenSend = 2000; // the frequency that this timer will execute here... 10 seconds. boolean metric = true; void setup() { gw.begin(incomingMessage, AUTO, true); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Distance Sensor", "1.0"); // Register all sensors to gw (they will be created as child devices) gw.present(0, S_DISTANCE); // Presenting custom gw.present(CHILD_ID_SONAR_MIN_RANGE, S_DISTANCE); //minRange // Request/wait for dimmer status //gw.request(CHILD_ID_SONAR_MIN_RANGE, V_VAR1); gw.request(CHILD_ID_SONAR_MIN_RANGE, V_DISTANCE); //gw.process(); //gw.request(CHILD_ID_SONAR_MAX_RANGE, V_DISTANCE); //gw.process(); //gw.saveState(1,2); boolean metric = gw.getConfig().isMetric; } void loop(){ // Process incomming message gw.process(); int dist = metric?sonar.ping_cm():sonar.ping_in(); //Serial.print("Ping: "); //Serial.print(dist); // Convert ping time to distance in cm and print result (0 = outside set distance range) //Serial.println(metric?" cm":" in"); if (millis() - lastSend > IntervalBetweenSend) { int dist = metric?sonar.ping_cm():sonar.ping_in(); if ( dist <= minRange && inRange == false) { gw.send(SonarMessage.set(dist)); inRange = true; lastSend = millis(); } if ( dist > minRange && inRange == true) { gw.send(SonarMessage.set(dist)); inRange = false; lastSend = millis(); } } } void incomingMessage(const MyMessage &message) { // echo "1;1;2;1;13;40" >> /dev/ttyUSB0 (Defining minrange to 40) // echo "1;2;2;1;13;50" >> /dev/ttyUSB0 (Defining maxrange to 50) Serial.print("Incoming Message"); // We wait for V_VAR1 value if (message.type == V_DISTANCE) { // Store state in eeprom //gw.saveState(message.sensor, message.getBool()); // Write some debug info Serial.print("Incoming change for sensor:"); Serial.print(message.sensor); Serial.print(" (type : "); Serial.print(message.type); Serial.print(")"); Serial.print(", New status: "); Serial.println(message.getInt()); if ( message.sensor == CHILD_ID_SONAR_MIN_RANGE ){ Serial.println("Updating Minrange"); minRange = message.getInt(); } } }``` -
can someone can just answer this question :
"gw.request(CHILD_ID_SONAR_MIN_RANGE, V_DISTANCE);", response is provided by the controller ?thank you :)
