serialEvent with Nano Every board

Projects Programming

Hi,

I'm trying to use serialEvent with a Nano Every board. Does it work ?

Prior, my code is running perfectly with a Nano. I need more memory, so I've decided to upgrade to Nano Every. Same code, just a compile and upload.

Then it does not work anymore.

Any feedback on serialEvent and Nano Every board ?

Thanks in advance,

#include <Adafruit_NeoPixel.h>

#define led_pin 2
String inputSerialString = "";
bool serialStringComplete = false;

Adafruit_NeoPixel strip = Adafruit_NeoPixel(134, led_pin, NEO_GRB + NEO_KHZ800);

void setup() {
  // Initialize the led strip
  strip.begin();
  strip.setBrightness(20);
  strip.show(); // All pixels to 'off'
  
  Serial.begin(9600);

  inputSerialString.reserve(200);
}

void loop() {
  // Process the command when a new one arrives
  if (serialStringComplete) {
    // Process the new command
    displayMyStuff(inputSerialString);

    // Clear the buffer
    inputSerialString = "";
    serialStringComplete = false;
  }
}

void serialEvent() {
  while (Serial.available()) {
    // get the new byte:
    char inChar = (char)Serial.read();
    // add it to the inputString:
    inputSerialString += inChar;
    // if the incoming character is a newline, set a flag so the main loop can
    // do something about it:
    if (inChar == '>') {
      serialStringComplete = true;
    }
  }
}

void displayMyStuff(String s) {
  strip.setPixelColor(0, strip.Color(255, 0, 0));
  strip.show();
}

Why do you want or need to use it. You might just as well use Serial.available() at the end of loop(), or any other point or points in you sketch, to see whether there is any serial data in the buffer. serialEvent brings nothing to the party but confusion

It would be a different matter if calling serialEvent were interrupt driven which would allow serial data to be serviced by an ISR, but it isn't
