Hello,

 

i was trying to connect sensors via i2c, and neither wiringPi.h nor i2c-dev.h are comiting Read/Write comands.
The file descriptor is given a value, so i think the connection worked, but functions like : i2c_smbus_read_byte_data(FILEDESCRIPTOR, (u_int8_t)REGISTERADRESS) just pop errors.
Do you guys have any idea?

Thanks for any help!

 

edit: 

i have also included /linux/i2c.h and the function error persists.

"I2C_SMBUS_READ_BYTE_DATA was not declared in this scope"

I can only assure you that I2C works. If you enable it in the armbian-config -> hardware.

I use it. But software you are trying to use (wiringpi) has nothing to do with Armbian. But I read around people use it on Armbian so its possible, but perhaps you need to adjust some things ...
