timer can capture full hi/lo pulse , just see my IR-receiver input:

0693W00000WIqQPQA1.pngi choose the timer5 clk+ prescaler, to get 1us tics; so on timer5 INT i get us count for hi and lo time of every incoming pulse.

perfect... right?

What microcode do you use?

Totally unrelated...

The advice was given. If you do not understand how timers work, open the reference manual and start learning!
