I am trying to get this basic tutorial working for the Nicla and Portenta H7 connected over ESLOV (I2C connection). The bug in the example code is that it only works for a little over half an hour before crashing.
I modified his code for debugging purposes:
arduino-libraries/Arduino_BHY2Host/examples/Accelerometer/Accelerometer_copy.ino:
#include "Arduino.h"
#include "Arduino_BHY2Host.h"
#include <LandoRGBLedPortenta.h>
SensorXYZ accel(SENSOR_ID_ACC);
LandoRGBLedPortenta portentaLeds;
const int MAX_DUPLICATE_READINGS = 10;
String colorToToggle = "white";
int duplicateReadings = 0;
static unsigned long printTime = 0;
static unsigned long startTime = 0;
static String timeToCrash = "";
static String lastAccelReading = "";
void setup()
{
Serial.begin(115200);
while(!Serial);
Serial.println("Serial started!");
portentaLeds.setColor("red");
BHY2Host.begin(false, NICLA_VIA_ESLOV);
Serial.println("BHY2HostSuccess!");
portentaLeds.setColor("green");
accel.begin();
Serial.println("Leaving setup!");
portentaLeds.setColor("blue");
printTime = millis();
startTime = printTime;
}
void loop()
{
BHY2Host.update();
if (millis() - printTime >= 1000) {
printTime = millis();
String accelReading = accel.toString();
if(accelReading == lastAccelReading) {
duplicateReadings++;
if(duplicateReadings == MAX_DUPLICATE_READINGS) {
timeToCrash = " " + String(printTime - startTime) + " ms";
colorToToggle = "red";
}
}
else {
duplicateReadings = 0;
}
Serial.println(String("Acceleration values: ") + String(accelReading) + String(timeToCrash));
portentaLeds.toggleColor(colorToToggle);
lastAccelReading = accelReading;
}
}
arduino-libraries/Arduino_BHY2/examples/App/App_copy.ino:
#include "Nicla_System.h"
#include "Arduino.h"
#include "Arduino_BHY2.h"
void colorCycle(int loops) {
for(int i = 0; i < loops; i++) {
nicla::leds.setColor(red);
delay(1000);
nicla::leds.setColor(green);
delay(1000);
nicla::leds.setColor(blue);
delay(1000);
}
nicla::leds.setColor(off);
}
void setup(){
BHY2.begin(NICLA_I2C, NICLA_VIA_ESLOV);
nicla::leds.begin();
colorCycle(5);
}
void loop(){
// Update and then sleep
nicla::leds.setColor(blue);
BHY2.update(500);
nicla::leds.setColor(off);
}
After 1,881,243–2,398,485 ms, the Nicla stops updating…
- The blue led on Nicla stops flashing, indicating that the BHY2.update(500); line in the loop probably caused an exception.
If I reset just the Portenta and relaunch the serial printer, the Portenta halts at the accel.begin(); line in the setup...
