Re: how to get x,y coordinates of hedge on the serial port of arduino?

Hello,
I don't quite understand what 7.11 of the packet streaming (FN0007) in the manual does, could you please explain?thank you.

Re: About the IMU

Thank you very much for your help. I have got the IMU data by running the code.If I want to read the direction information, do I need to use compass_x and compass_y data, I don't quite understand what they mean. :o

About the IMU

How can I get IMU data from the stream? Is there any Arduino code available to get IMU data?

How to use IMU and ultrasonic for precise navigation

hello!
I have bought a hedgehog with IMU, I want to use IMU and ultrasonic to achieve accurate navigation and combine with Kalman filtering, but I don't know how to do. :|

Re: how to get x,y coordinates of hedge on the serial port of arduino?

Hello, Please check the ultrasonic coverage. Does your mobile beacon on line of sight with stationary beacons? Please refer to operating manual, especially sections 10.4, 10.5 10.6: https://marvelmind.com/pics/marvelmind_navigation_system_manual.pdf Check ultrasonic signals as shown in section 10.5...

Re: how to get x,y coordinates of hedge on the serial port of arduino?

Thanks for your help very much.I have solved this problem.
But when I use the coordinates to control my robot,I find that the coordinate is not stable, it always drift. So how can I improve coordinate stability?

Re: how to get x,y coordinates of hedge on the serial port of arduino?

Hello. This is not a problem but a feature. Locations of all hedgehogs are available from any hedgehog or from modem. You can separate them by address of hedgehog transmitted in offset 22 of the data packet. Please see section 1.1.2 of the protocol: https://marvelmind.com/pics/marvelmind_beacon_int...

Re: how to get x,y coordinates of hedge on the serial port of arduino?

Hello!
When I connect a hedgehog to arduino(I want to obtain its coordinate), and I wake up two hedgehogs. But I obtain the two hedgehogs coordinates mixed together from the Serial monitor. So what's the problem? How can I separate them?

Re: how to get x,y coordinates of hedge on the serial port of arduino?

When I want to obtain coordinate and send it to the arduino, I could only pin the RX0, When I change the pin to RX1,I can't get anything.
