I’ve came accross with a strange issue while calling ControlMotoDriver using GrovePi library (dll). </s><i>
</i>sensorController.ControlMotoDriver(true);
public void ControlMotoDriver(Boolean onoff)
{
if (onoff)
{
motor.drive1(100);
motor.drive2(100);
} else
{
motor.drive1(0);
motor.drive2(0);
}
}<e>
Calling this method causes the whole application to crash (restart). Is there any known issues around that? Is there any possiblity that application is crashing because using wrong port on the GrovePi+?
Any progress on that? We’ve bought GrovePi+, because there is written that is can be used for fast prototyping - now we have bunch of problems, not only with Moto Driver, but with LCD display too…
Hi Nace, Sorry for the late response, we try to simulate the issue. but we stuck at some place. I talked with software team manager. He is looking at the issue now. thanks.
No, the I2C Grove doesn’t care which I2C port you’re connecting it to, your problem might be caused by bad network communication to the Azure, in which case the program will throw an exception which is not catch-ed. I’ve updated the code to catch these exceptions. Please try our latest App bundle with instructions here: <LINK_TEXT text=“https://github.com/Seeed-Studio/AzureGr … /README.md”>https://github.com/Seeed-Studio/AzureGroveKit/blob/master/README.md</LINK_TEXT>
I’ve updated my code with your improvements on Github. Now i am able to print out the error. After calling the following line:
</s>sensorController.ControlMotoDriver(true);<e>
i got this error:
“Sorry…The system cannot find the file specified. Slave address was not acknowledged. Contact us for help”
Otherwise the communication with Azure IoT HUB is working fine - we’ve already managed to establish a connection for other sensors (temp., hum., PIT, …).
I’ve successfully driven the Grove - Mini I2C Motor Driver, and there’s no same issue reported for this, so I can temporarily conclude that your issue isn’t a common one.
Could you share more informations about your research? Have you tried other I2C Groves e.g. Grove - OLED Display 0.96" ?
From the error message
What I get from the message is, the Grove - Mini I2C Motor Driver may be damaged. Have you tried to drive this Grove via an Arduino board? Or grab some board that can do I2C scan, does the Grove - Mini I2C Motor Driver respond to any I2C communications?
