Tic36V4 - no device was found - [SOLVED]

Robotics and electronics discussion Software and microcontrollers

Hi,
After installation of pololu-tic-1.8.1-linux-rpi according to README file, I got the following error:

$ticcmd -s
Error: No device was found.

But the “sudo i2cdetect -y 1” returns the correct device address 0x0E:
$sudo i2cdetect -y 1
… 0e …

Any idea of what is going wrong here?
Thx,
Stephane

Apparently ticcmd works only with an USB connection but not with a I2C connection.
That was not clear to me when reading the doc.

Cheers,
Stephane

Hello.

I am glad to hear you figured out the problem!

Yes, ticcmd can only communicate with the Tic via USB; I apologize for any confusion. For examples and resources with guidance about how to control the Tic via I2C, I suggest referring to the “Setting up I²C control,” I²C command encoding,", and the “Writing PC software to control the Tic” sections of the Tic user’s guide. Our Tic Stepper Motor Controller library for Arduino might be a useful reference as well.
