[Flashforth-devel] Microsecond counter problem, please help

[Laszlo K. <Ko...@ce...>]

I am newbie in forth and especially MCUs
I would like to ask for help.
I would like to write a driver for DHT-22 humidity/thermo sensor. It
needs measure microsecond resolution changes in pin state, so I wrote a
small code in order to count microseconds based on this article:
https://www.reddit.com/r/arduino/comments/1q1chr/using_timer1_to_count_clock_cycles/

I try to implement it but failed in several various ways.
once it looks like stuck in a infinity reset, sometimes no prompt after
running, sometimes flood garbage when use 'words' after running the
code.

What mistake I made in this code? 
Please help me!

Thanks in advance!
