Add Condition to Stop read_response Function in i2c.py

[YairBenamou]

I’d like to propose an enhancement for the py532lib library, specifically in the i2c.py file. Currently, the read_response function continuously listens for incoming NFC chips without a built-in mechanism to stop this process based on a condition.

I suggest adding a simple flag to the class that can be used to control the execution of the loop.

def __init__(self, address=PN532_I2C_SLAVE_ADDRESS, i2c_channel=RPI_DEFAULT_I2C_NEW):
    ...
    self.condition = True

def read_response(self):
    ...

    while self.condition:

        ....

This change would provide more control over the NFC reading process, enabling users to stop listening based on specific conditions like listening for incoming chips only on working hours.

I have not found any existing method to stop the read_mifare() function from waiting for incoming chips, so this enhancement would fill a useful gap in the library’s functionality.

Thank you.
