If you are interested in running any of the examples for I2C written in C/C++ as a regular user (not root) perform the following steps:
- Remove line "wiringPiSetup();" in "HTU21D_test.c"
- Add your user in "i2c" group
Simple application to test if a piezo buzzer attached to pin 11 is working.
Install wiringPi and after that execute the following command to build the application:
cd buzzer/c/
gcc beep.c -o beep -lwiringPi -std=c99
Execute the following command to run the application:
sudo ./beep
Implementation of the Imperial March from Star Wars.
Install wiringPi and after that execute the following command to build the application:
cd buzzer/c/
gcc starwars.c -o starwars -lwiringPi -std=c99
Execute the following command to play the Imperial March:
sudo ./starwars
Install i2c tools:
sudo apt-get install i2c-tools
Enable i2c on Raspberry Pi with Raspian GNU/Linux distribution:
sudo raspi-config
Go to Advanced Options > A7 I2C and reboot the board
Verify that TSL2561 is detected on i2c address 39 on bus 1:
pi@raspberrypi:~ $ i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f

Build and run the source code
cd TSL2561/c/
make
./TSL2561_test
Build and run the source code
cd MAX44009/c/
make
./MAX44009_test
