exploring-cpp - lesson_4_i2c example not working on Intel Joule

[fmanea]

I have tested on Ubuntu Core/ Ref-Os-IoT 1705( mraa 1.7.0, upm 1.3.0).

On Ubuntu Core:
jhd1313m1_command: mraa_i2c_write_byte_data() failed
jhd1313m1_set_color: mraa_i2c_write_byte_data() failed
jhd1313m1_data: mraa_i2c_write_byte_data() failed
On Ref-Os-Iot:
jhd1313m1_init: mraa_i2c_init(LCD) failed.
terminate called after throwing an instance of 'std::runtime_error'
what(): Jhd1313m1: jhd1313m1_init failed

Is there a problem with Intel Joule I2C? I saw that other users had problems with it here:

Did this example really worked on Intel Joule?
