NewPing library + Arduino UNO R4 Minima

Projects Libraries
1

Hello,
I'm trying to use the newping library with a SR04M sensor and an arduino UNO R4 minima. When uploading the scketch i get the following message :
ATTENTION: la bibliothèque NewPing prétend être exécutable sur la (ou les) architecture(s) avr, arm, megaavr, esp32 et peut être incompatible avec votre carte actuelle qui s'exécute sur renesas_uno.

Am I missing a configuration or something to do ? Or is it just not compatible ?
Thanks for your help :slight_smile:

Not every library is compatible with every board/processor (especially newer boards/processors). It however might be; the only way to find out is to test.

Note:
Is that the only message or do you also get errors?

You can test it without a library:

The mechanics are plain state change detection.

Thanks for your answer.
I get no errors, only that message, but nothing is happening when i upload my sketch to the minima, so i guess it is a compatibility issue...
I'm using this sample script from the library, connexions are ok :

// ---------------------------------------------------------------------------
// Example NewPing library sketch that does a ping about 20 times per second.
// ---------------------------------------------------------------------------

#include <NewPing.h>

#define TRIGGER_PIN  12  // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define ECHO_PIN     11  // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 400 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.

NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.

void setup() {
  Serial.begin(115200); // Open serial monitor at 115200 baud to see ping results.
}

void loop() {
  delay(50);                     // Wait 50ms between pings (about 20 pings/sec). 29ms should be the shortest delay between pings.
  Serial.print("Ping: ");
  Serial.print(sonar.ping_cm()); // Send ping, get distance in cm and print result (0 = outside set distance range)
  Serial.println("cm");
}

I'm not sure I understood correctly what you mean by "nothing is happening". Please provide a more detailed description of what you mean by this in a reply on this forum thread to help us to understand it.

Did you open the Arduino IDE Serial Monitor? If so, did you see anything printed there?
