aw9523b 1.1.0

a library for raspberry pi gpio extend using aw9523b

Example

Input

from AW9523B import EX_GPIO,Port0,Port1

fiveWaySwitch = [Port1.PIN7, Port1.PIN6, Port1.PIN5, Port1.PIN4,
                 Port0.PIN7, Port1.PIN0, Port1.PIN1, Port1.PIN2, Port1.PIN3, Port0.PIN0]
key = ["A2", "B2", "C2", "OK2", "D2", "A1", "OK1", "B1", "C1", "D1"]

for pin in fiveWaySwitch:
    EX_GPIO.setup(pin, EX_GPIO.INPUT)

if __name__ == "__main__":
    import time
    import RPi.GPIO as GPIO

    def my_callback(channel):
        pin = EX_GPIO.readInput()
        if pin:
            # print("my_callback",pin)
            for x in range(len(fiveWaySwitch)):
                if fiveWaySwitch[x] is pin:
                    print("key:", key[x])
                    break

    aw9523Int = 27
    GPIO.setmode(GPIO.BCM)
    GPIO.setup(aw9523Int, GPIO.IN, pull_up_down=GPIO.PUD_UP)
    GPIO.add_event_detect(aw9523Int, GPIO.FALLING, callback=my_callback)
    EX_GPIO.readInput()
    while 1:
        try:
            time.sleep(1)
        except KeyboardInterrupt as e:
            GPIO.cleanup()
            break

OUTPUT

from AW9523B import EX_GPIO,Port0
import time

led1 = Port0.PIN5
led2 = Port0.PIN6

EX_GPIO.setup(led1, EX_GPIO.OUTPUT)
EX_GPIO.setup(led2, EX_GPIO.OUTPUT)



if __name__ == "__main__":
    while 1:
        time.sleep(5)
        EX_GPIO.output(led1,EX_GPIO.HIGH)
        EX_GPIO.output(led2,EX_GPIO.LOW)
        time.sleep(5)
        EX_GPIO.output(led1,EX_GPIO.LOW)
        EX_GPIO.output(led2,EX_GPIO.HIGH)
