pulseIn support on attiny25 / 45 / 85

[kotsklont]

Dear David,
Your tutorial on high low tech has helped me a lot.
I would like to suggest something for the supported commands:

• pulseIn only works correctly on pin 7 (pin 2 in arduino) on the attiny25 / 45 / 85 when reading pulses for IR remote signal or RC control signals. (might have something to do with INT0)
• I haven't been able to test it yet, but this problem could also appear in attiny24 / 44 / 84. According to the datasheet of attiny24 / 44 / 84, INT0 is located on pin 5 (pin 8 in arduino).

While searching for this problem I found a lot of forum posts about similair problems so I think this information could be a great addition to your tutorial.

pieter,
