Interrupt for Adafruits Neotrellis button/led board

[Moris526]

Hi all.

I have 32 Adafruits Neotrellis boards (8x8 led/button) making a big led/button board, controlled with Raspberrypi zero.

Adafruits page says the interrupt works with python (https://learn.adafruit.com/adafruit-neotrellis?view=all) but in the sample code theres is not that function. It is in the Arduino code.
This is my first project so im trying to make it work.

I found some interrupt code for python (http://raspi.tv/2013/how-to-use-interrup...d-rpi-gpio)

I had no luck. Im trying different things but dont have enough knoledge.

Any help is welcomed

I need the interrupt because the time it takes to read the entire board is too much

The code I found is for a button, not a board .....so...

import RPi.GPIO as GPIO
import time
import serial

GPIO.setmode(GPIO.BCM) 
GPIO.setup(5, GPIO.IN, pull_up_down=GPIO.PUD_UP)



ser=serial.Serial('/dev/ttyS0',57600 )

from board import SCL, SDA
import busio
from adafruit_neotrellis.neotrellis import NeoTrellis
from adafruit_neotrellis.multitrellis import MultiTrellis


i2c_bus = busio.I2C(SCL, SDA)


trelli = [
    [NeoTrellis(i2c_bus, False, addr=0x35), NeoTrellis(i2c_bus, False, addr=0x3A), NeoTrellis(i2c_bus, False, addr=0x4A), NeoTrellis(i2c_bus, False, addr=0x33), NeoTrellis(i2c_bus, False, addr=0x4B), NeoTrellis(i2c_bus, False, addr=0x45), NeoTrellis(i2c_bus, False, addr=0x4C), NeoTrellis(i2c_bus, False, addr=0x42)],
