Multisensor portable station, GPS not upgrading

[andreadp271]

Hi, i'm building a project with:
-Arduino Nano RP2040
-DHT11 sensor from Makeblock
-L80-M39 GPS
-2.4 TFT SPI 240 X 320 Touchscreen

In this project i have 4 pages where i display sensors data's. The DHT11 datas are always upgrading but not the GPS one's.

For the GPS i'm using the Adafruit library with the Hardware serial connection (TX and RX) [ No TinyGPS because my arduino can't work with Software Serial library ].

With the Adafruit example my Arduino keeps upgrading the datas.

Adafruit Example:

// Test code for Ultimate GPS Using Hardware Serial (e.g. GPS Flora or FeatherWing)
//
// This code shows how to listen to the GPS module via polling. Best used with
// Feathers or Flora where you have hardware Serial and no interrupt
//
// Tested and works great with the Adafruit GPS FeatherWing
// ------> https://www.adafruit.com/products/3133
// or Flora GPS
// ------> https://www.adafruit.com/products/1059
// but also works with the shield, breakout
// ------> https://www.adafruit.com/products/1272
// ------> https://www.adafruit.com/products/746
//
// Pick one up today at the Adafruit electronics shop
// and help support open source hardware & software! -ada

#include <Adafruit_GPS.h>

// what's the name of the hardware serial port?
#define GPSSerial Serial1

// Connect to the GPS on the hardware port
Adafruit_GPS GPS(&GPSSerial);

// Set GPSECHO to 'false' to turn off echoing the GPS data to the Serial console
// Set to 'true' if you want to debug and listen to the raw GPS sentences
#define GPSECHO false

uint32_t timer = millis();


void setup()
{
  //while (!Serial);  // uncomment to have the sketch wait until Serial is ready

  // connect at 115200 so we can read the GPS fast enough and echo without dropping chars
  // also spit it out
  Serial.begin(115200);
  Serial.println("Adafruit GPS library basic parsing test!");

  // 9600 NMEA is the default baud rate for Adafruit MTK GPS's- some use 4800
  GPS.begin(9600);
  // uncomment this line to turn on RMC (recommended minimum) and GGA (fix data) including altitude
  GPS.sendCommand(PMTK_SET_NMEA_OUTPUT_RMCGGA);
  // uncomment this line to turn on only the "minimum recommended" data
  //GPS.sendCommand(PMTK_SET_NMEA_OUTPUT_RMCONLY);
  // For parsing data, we don't suggest using anything but either RMC only or RMC+GGA since
  // the parser doesn't care about other sentences at this time
  // Set the update rate
  GPS.sendCommand(PMTK_SET_NMEA_UPDATE_1HZ); // 1 Hz update rate
  // For the parsing code to work nicely and have time to sort thru the data, and
  // print it out we don't suggest using anything higher than 1 Hz

  if (GPS.newNMEAreceived()) {

    // we end up not listening and catching other sentences!
    // so be very wary if using OUTPUT_ALLDATA and trying to print out data

Hello andreadp271
Can the GPS receiver see satellites or only the ceiling of your room?
Have a nice day and enjoy programming in C++ and learning.

@andreadp271

[ No TinyGPS because my arduino can't work with Software Serial library ].

TinyGPS does not 'require' the Software Serial library as it will work with standard hardware serial ports.

[andreadp271]

yes he can see them, using the adafruit example the gps works very well

[andreadp271]

do you have an example? because i find examples only with Software Serial

[jremington]

@andreadp271

i find examples only with Software Serial

Use Serial.read() or Serial1.read() instead of SoftwareSerial.read().
