The user code should call micropython.alloc_emergency_exception_buf(size) where size is the size of the buffer used to print the argument passed to the exception. With the test code from #732, and a call to micropython.alloc_emergenncy_exception_buf(100) the following error is now printed: ```python >>> import heartbeat_irq Uncaught exception in Timer(4) interrupt handler Traceback (most recent call last): File "0://heartbeat_irq.py", line 14, in heartbeat_cb NameError: name 'led' is not defined ```
