grizzlei / mpu6050 Goto Github PK

this program will read gyro and accelerometer sensor data from mpu6050 imu and forward it to serial port, so you can work with the data on your development pc. in main.c mpu6050 is initialized with ±500 °/s gyro, ±4g accelerometer configurations.

following format is what you will receive from serial port, which are respectively accelerometer's x, y, z and gyro's x, y, z values:

-11224,6704,-88,-84,-99,-7

you can use libimu (https://github.com/grizzlei/libimu) to process the data you get from sensors. for a quick start, you can compile and use demo.c on your development pc.

first, enable i2c-0 and uart-1 interfaces from underlying operating system's tool. if you have to use a different configuration, update the code accordingly.

for armbian, use armbian-config

usb-ttl wiring is not necessary if you don't want gyro and accelerometer sensor data over serial.
