How to get Barcode label from Pixy2 with Arduino?

Pixy Software
#1

I want to trigger an event with my arduino code when Pixy2 detect a certain barcode and keep the event going for as long as the barcode is in sight.

if barcode 14 is detected then trigger event
while barcode 14 is being detected > loop

How do I do this?

My code:

#include <Pixy2.h>
Pixy2 pixy;
void setup()
{
Serial.begin(115200);
Serial.print(“Starting…\n”);
pixy.init();

  pixy.changeProg("line");

}
void loop()
{
int8_t i;
char buf[128];
pixy.line.getAllFeatures();
if (pixy.line.barcodes)
pixy.line.barcodes->print();
}

The serial monitor gives me: Barcode: (75 41), val: 14 flags: 2

It’s unbelievable that none of the pixy example code comes with a simple blink example, it’s all I need. Receive input from Pixy, let the LED on the Arduino blink if a certain object is recognized…

Hello,
If you want to get barcodes continuously, you should check out getAllFeatures(), which will return all features regardless of whether they’ve been detected before.

Hope this helps.
