Examples for getting started and testing ANAVI hardware
ANAVI Infrared pHAT is an open source hardware Raspberry Pi add-on board with IR receiver, transmitter, UART and 3 I2C slots for sensors. The project allows you to convert your Raspberry Pi into a smart remote control using the open source software LIRC.
ANAVI Infrared pHAT Raspberry Pi HAT includes:
- IR LED
- IR photo sensor
- Slots for up to 3 plug and play I2C sensors
User's manual for ANAVI Infrared pHAT is available at: http://anavi.technology/files/anavi-infrared-phat.pdf
It is mandatory to enable I2C to use any of the sensors supported by ANAVI Infrared pHAT Raspberry Pi HAT.
Follow the steps below to use the BMP180 I2C temperature and barometric pressure sensor with ANAVI Infrared pHAT:
-
Connect BMP180 to any of the I2C slots on ANAVI Infrared pHAT using male to female Duport jumper wire.
-
Type in the following command and verify that the address of the sensor is listed:
sudo i2cdetect -y 1
- Type in the following commands to build and run the sample application that display temperature and barometric pressure:
cd ~/anavi-examples/sensors/BMP180/c/
make
./BMP180
- Verify that the output is similar to (the exact values depend on the atmospheric condition):
pi@raspberrypi:~/anavi-examples/sensors/BMP180/c $ ./BMP180
