Checking a bit sequence

[cmisztur]

I'm working with SX1509 peripheral.

Based on this value '00000000 00000110' from 0x18+0x19 I know that pin 01 and pin 02 caused an interrupt. Now I need to read IO state for pin 01 and pin 02.

Below code works, but can you suggest improvements?

def digitalReadFromInterrupt(self,interruptSource):
        readResults = []
        
        for i in range(15,0,-1):
            if interruptSource & (1<<i):
                readResults.append([i,self.digitalRead(i)])

        return readResults
