"Could not find ADXRS450 gyro on SPI port 0" Error - Java

[Arhowk]

Have you hooked up a probe to the clock and message lines to the spi gyro to make sure that valid data is being exchanged? If the RIO isn't sending data you may have a firmware issue. If data is being sent than either your not lighting the right chip select line or you have an issue with the gyro

Hi mikets and Arhowk, thank you for your replies.

Mikets, under the hood, your code looks similar to our code. I downloaded it and ran it, and I get the same problem. This leads me to believe we have a hardware issue. But, the knowledge that other teams are using this successfully with Java is important, so thank you.

Arhowk, no, we haven't done that. I think that's what our next step needs to be, but unfortunately due to resource constraints (in particular time), I'm not sure that we will in the imminent future. I was hoping this would just be a silly code issue.

I think for now, we will be reverting to the old kit of parts gyro. If we have time to either test our SPI or test a different ADXRS450 sometime before the end of season, we'll try that. If not, perhaps after our season ends.

Thanks again for the help!

We use the same gyro and it works fine. Here is the line that I used to call the gyro.

public static ADXRS450_Gyro gyro= new ADXRS450_Gyro();

Do you guys use any roboRIO expansions since I don't think it is an error how you guy's code
