Is there in fact a way (on Linux - Raspbian) to get a tickcount with
higher resolution than 1 ms?
I need us so I can time between two events (pulse rise and pulse fall)
which are 20

Hi,
I recently built a Weather-Station using an RPi and Lazarus/FPC, but:
anything that's not I2C or SPI (or otherwise supported within the RPi
hardware) is IHMO hard to realize. I went on and used an AVR (Arduino)
to interface the DHT11, and hooked that up to the Pi with UART (just
before dumping

As Alexander writes, the right way to do such a task is to use a hardware
timer in capture mode. I don't know how difficult this is on RPi.
