RDAS Compact Memory Failure - Ideas?

[jderimig]

This is a dead thread, so since we are already on the same page:

I would really like to use the accelerometer throughout the launch. Not only to establish the gravity vector but to assist the gyro/drift during flight. Unfortunately, as I'm sure this was the reason you alluded to the omittance of the accelerometer during flight, accelerometer vibrations during flight muck up raw data values rendering the IMU worthless in the air.

mikec is right, you probably should start another thread on this. You can use the accelerometer during flight to determine the external forces (drag and thrust) on the rocket but you CANNOT establish the gravity vector during flight.

Here as a thread on the subject which can review which covers this discussion starting at post #23, have fun. https://www.rocketryforum.com/showt...DURING-Actual-Flight&highlight=detect+gravity

Gravity in fight isn't always intuitive, until you hit the ground.

Thanks. I'm not sure I would get much help from this crowd, however, and this being the reason I was specifically targeting you in this thread. Thank you for your help.

To mikec: Noted.

To OP: I apologize for distracting your audience. It was my understanding that you determined your issue to be a hardware one and that the discussion was over with your post #8.

It looks to me based on your report and the manual https://www.aedelectronics.nl/rdas/download.htm that it's the RAM chip that's bad, not the flash (since the bootloader works and you can update the firmware.) You should check the solder joints on the RAM. It might be possible to replace that chip, though it looks more to me like a bad connection. Without a good photo of the board I can't tell which chip the RAM is or what type.

I was hoping for support from them.
