Where's your code from my_accessory.c?

i can share, but homekit is working fine and i was able to add one physical button with red led and its working fine with homekit..

my concern is how i can add second ace button to green led?
i am trying but something going wrong in my coding as above, when i press any button only red or only green respond in homekit.

please guide me correct way of code to add second acebutton to above code.

rather than repeat yourself ... you'll get more help if you respond to questions
