wiringpi and interrupt issue - Raspberry Pi Forums

i using pi2 , mcp23017 expander. have succesfully setup wiringpi in can press switch connected input on bank b , lights corresponding led on bank a.
problem trying use interrupts - have code -

code: select all

import wiringpi  import sleep  pin_base = 65 i2c_addr = 0x20  wiringpi.wiringpisetup()                      # initialise wiringpi wiringpi.mcp23017setup(pin_base, i2c_addr)       wiringpi.pinmode(80,0)     # sets pin of mcp23s17-0 input wiringpi.pullupdncontrol(80, 1) #pulldown wiringpi.wiringpiisr(80, int_edge_rising, my_int)  wiringpi.pinmode(65,1)     # sets pin of mcp23017-0 output wiringpi.digitalwrite(65,0) # sets  pin of mcp23017-0 0 (0v, off)   def my_int():     print('led on.')     wiringpi.digitalwrite(65,1)     return true  while true:     time.sleep(1)     print('waiting...')     wiringpi.wiringpiisr(80, int_edge_rising, my_int)     wiringpi.digitalwrite(65,0)

error message nameerror: name int_edge_both not defined.
thought line 12 define line.
don't mind if rising or falling trigger.

missing?
thanks
