I m facing with this error Board at COM1 is not available I am using ardunio ide 1.6.5 preinstalled in udoobuntu 2.0 rc desktop trying to connect my adafruit ultimate GPS rx and tx in pin 0 and 1 GND and 3v3 pin in my udoo neo board I have downloaded the library of GPS from git and copied it in ardunio library folder. I am new with this can any one help me.
The arduino side is not on COM1 but on /dev/ttyMCC so set your IDE to that (as it is preinstalled). Second, to talk with your GPS shield from Arduino side you better use the build in Serial0, available on pin 0 and 1. Perhaps you have to modify some sketches and libraries to adapt to this situation. If you want to talk from the Linux side to the Arduino side you use Serial. If you want to use the GPS data on the Linux side you first read them with Serial0 from shield to Arduino and then send them with Serial to the Linux side. See also the communication part of the Neo documentation.
need some help. im trying to run a basic script with related to adafruit ultimate GPS but as udoo neo not supported with SoftwareSerial I dont know what to do SoftwareSerial mySerial(3,2); Adafruit_GPS GPS(&mySerial); I am unable to get any values on ttyMMC getting an error Kindly help me.
You have to erase all SoftwareSerial references and use Serial0 instead. Change your code with Adafruit_GPS GPS(&Serial0); Be sure you connect the TX and RX pins of your gps to pin 0 and 1 (not sure I have the correct order, could be the other way) please check the documentation yourself.
I connected Rx and tx to pin 0 and 1 and trying to run this code it successfully uploads but no output Code: #include <Adafruit_GPS.h> Adafruit_GPS GPS(&Serial0); String NMEA1; String NMEA2; char c; void setup(){ Serial.begin(115200); Serial.println("Adafruit GPS library basic test!"); GPS.begin(9600); GPS.sendCommand("&PGCMD,33,0*6D"); GPS.sendCommand(PMTK_SET_NMEA_UPDATE_10HZ); GPS.sendCommand(PMTK_SET_NMEA_OUTPUT_RMCGGA); //GPS.begin(9600); //GPS.sendCommand(PMTK_SET_NMEA_OUTPUT_ALLDATA); delay(1000); } void loop(){ readGPS(); } void readGPS() { while(!GPS.newNMEAreceived()) { c=GPS.read(); } GPS.parse(GPS.lastNMEA()); NMEA1=GPS.lastNMEA(); while(!GPS.newNMEAreceived()) { c=GPS.read(); } GPS.parse(GPS.lastNMEA()); NMEA2=GPS.lastNMEA(); Serial.println("Adafruit GPS library basic test!"); Serial.println(NMEA1); Serial.println(NMEA2); }
I looked in the Adafruit_GPS library and it is full of references to softserial. So this could be an issue. To get rid of the library first what happens if you run the following code? Do you see GPS data arriving in the Serial Monitor Code: void setup() { Serial.begin(115200); // setup serial for serial monitor delay(100); Serial.println("GPS test Started"); // GPS Setup serial0.begin(9600); // adapt speed for your GPS, try 4800 if ails delay(100); // Cut first gibberish while(serial0.available()) if (serial0.read() == '\r') break; } void loop() { String s = checkGPS(); if(s && s.substring(0, 6) == "$GPGGA") { Serial.println(s); } } // Check GPS and returns string if full line recorded, else false String checkGPS() { if (serial0.available()) { char c = serialGPS.read(); if (c != '\n' && c != '\r') { stringGPS = c; } else { if (stringGPS != "") { String tmp = stringGPS; stringGPS = ""; return tmp; } } } return false; }

You did not change all serial0 into Serial0 Furthermore it was an old sketch I found somewhere on the net and modified a little hoping it would compile. But debugging is an task you have to be able to do yourself.
can you check with this atleast gps:30: error: 'serialGPS' was not declared in this scope gps:33: error: 'stringGPS' was not declared in this scope gps:37: error: 'stringGPS' was not declared in this scope
stringGPS was not declared yet. Add a line at the beginning of the sketch to declare it: String stringGPS ="";
