This is my i2c sensor: http://www.mindsensors.com/rpi/76-smartdrive-high-current-motor-controller look in pdf in Documents sessions please
Based on this google guide https://developer.android.com/things/sdk/pio/pio-cli.html What I need to put in XX ZZ YY UU to run motors in determined speed, direction, duration, etc...
e.g.: pio i2c I2C1 0x1B write-reg-buffer 0xXX 0xYY 0xUU 0xZZ
As (in this case) I will use writeRegBuffer() on my android things app to run one, two or both motors in determined spped, direction, duration, etc?
e.g.: I used (via jcenter) this driver in intel edison/android things DP2, but now I want to create an AT driver to use smartdrive in nx pico and rpi 3, because there would be no more mraa:

My questions is: If you see here: https://github.com/intel-iot-devkit/upm/blob/master/src/smartdrive/smartdrive.hpp and especially in this: https://github.com/intel-iot-devkit/upm/blob/master/src/smartdrive/smartdrive.cxx in function
SmartDrive::Run_Seconds(int motor_id, int direction, uint8_t speed, uint8_t duration, bool wait_for_completion, int next_action )
you will see writeArray(array, sizeof(array));
ok. I need help to use this in android things using writeRegBuffer(int reg, byte[] buffer, int length) and write(byte[] buffer, int length)
