possibilities:
a) drive int 0 directly and int1 through an inverter b) use a 'continuously adjusted' timer to create the other interrupt c) switch to e.g. a SILabs chip and use a comparator interrupt which has interrupts on both edges d) Insert an XOR between the source and the interrupt. Make the interrupt level triggered. Connect the other input to the XOR to a port pin. In the ISR complement that pin. Work it out on a piece of paper, you will see. Erik |
