Hi
I have trouble with my x-y Gyro readings. I’ve got the new APM with an IMU Shield bought at buildyourowndrone. When I connect it to hk gcs the x-y gyro readings drift away. Sometimes it is drifting slowly and is reacting to movements; sometimes it drifts fast (like 60 degrees in 5 seconds) and hardly reacting to movements. As this sounds much like a soldering error, I reflowed my solder connections (twice) but still getting errors.
I tried to measure my connections (from header to the destination, for example from header to CLI / flying switch). The ones I measured were good, although there were some I don’t know where they are leading. I looked up in the EAGLE files, but it seems to be an older layout and not every pin connected (?) Is there another plan where I see where I can measure the remaining pins?
If the two boards are together and I measure form solder connection to solder connection, everything is fine.
Currently I am running only the APM with Shield, no gps or xbees. I am using APM2.012 with minimum config:
#define GPS_PROTOCOL GPS_PROTOCOL_NONE
#define GCS_PORT 0
#define GCS_PROTOCOL GCS_PROTOCOL_MAVLINK
I did reset the EEPROM, IMU test in CLI looks the same.
As I only have a simple magnifying glass, I am not able to see whether to gyro connections are ok.
Any advice would be greatly appreciated.
Thanks
