 |

Hi Guys
Is it at all possible to do inputcapture using the 8 bit Timer 2 (on zx-128ne)?

The 8-bit timers (like Timer0 and Timer2) don't have an input capture unit on any of the AVR devices that I've worked with.
You might be able to accomplish a similar result using a pin change interrupt or external interrupt in conjunction with a timer. The accuracy of this method won't be as good as that realized by using the input capture unit, though. |

ok no worries.
Just been reading about the new atmel XMEGA, is there any possibility of the zx range including these in the future?

Perhaps. The biggest obstacle at this time is that they aren't available in production quantities. |
