Now it becomes really complicated

I connected a tsop1740 to my circuitry and sent the attached signal(lower area) to see this response from the pic(upper area).

I am very confused but this explains why my rc5 decoding did not work.

The pic code responsible is something like

WHILE tsop1740 = 1
... count microseconds
WEND
..write to array

WHILE tsop1740 = 0
... count microseconds
WEND
..write to array

which is being repeated till no signal is there anymore and finally written to the eeprom. Then I reconstruced it and created a wave-file out of it to show. It is 192000 Hz. The area shown is roughly 29ms.

Do you see a pattern?
