[Autopilot] 6DOF IMU kit

[dong L. <don...@ya...>]

Hello Trammell,

I bought 6 DOF IMU kit several weeks ago, but I am still unsucessful to make  it working. Let me tell you the history.

When I ordered it, I asked Futaba PPM version, and Rotomotion sent to me.

However,  PPM reading didn't work with Futaba system, and I asked JR version again, and Rotomotion gradly sent it to me. 

Yesterday, I tried with JR version again, but the symptom was almost same.

PPM readings are always full scale, and do not response at all.

I suspected my PPM signal had a problem, but PPM readings work fine with the image code for atmega 163 (8mhz) which I downloaded from your web site, and programmed it into another chip, Atmega 163 (I replaced the crystal also to 8 mhz)

But, this code does not work for auto mode, (in manual mode, all servos work fine, but in auto mode servos do not response to sensor boards, X,Y, Z)            In IMUviewer, ADC works fine

Let me summarize what I have done so far.

1) I have only Futaba system 

2) ADC and IMU monitoring are always fine in IMUviewer

3) RS-232 works fine always

4) Image codes for atmega 32 (16mhz), JR and Futaba versions, do not work for  PPM reading, while ADC and IMU work OK

5) Image code from Rotomotion web site (JR version atmega 163 8mhz)  works ADC,IMU and PPM readings, even though I use Futaba system. But servos work only on manual mode.

6) When in Auto mode, servos do not response sensor boards. (but this time ADC works on IMUviewer)

Could you tell me possible causes?

By the way, what is the correct fuse settings for atgema 32 and atgema 163?

Can wrong fuse setting  casue this kind of problem ?

Thanks for your answer in advance.

Dong
