Hi, I've collected some questions during my first developed program, which can be found her: http://mbed.org/users/Renegr/programs/IRQKeypad1/m216ms
1. Is there an alternative to polling whether the isr has started, maybe something like "if( waitforirq(irqn))"? 2. If I set a pin as output, which was previously handled as an irq input, do I need to setup the irq handler again? Or is it enough to just set the direction to input to get the irq? (the local InterruptIns are just a workaround to setup the irqIn again after 1 key was pressed)
Any other constructive suggestions? You're welcome!
thx in advance, René
