FreeBSD DHT11/DHT22/AM2302 sensor reading program

This program is a slightly modified version of Adafruit's Python DHT library but with FreeBSD's native libgpio library. Run ./build.sh to build the program. Output executable is test_dht11. The GPIO pin and sensor type parameter is hardcoded in main.c, so change it accordingly. This program is tested with DHT11 and a Raspberry Pi 1 board.

TODO list

• add GPIO pin and sensor type argument for running the program
• different single board computer CPU might have different clock. Several variables in pi_dht_read.c must be rechecked for different CPU clock
