Hi Chris,

I had brown out problems to start with, I have isolated the power supplies running a seperate battery and BEC to the input and receiver. Ive got to the point of isolating the positive/power from the ESC to the APM2 output positive rail. Only the negative and and control signal are connected to the APM2 from ESC and steering servo, the postive is connected to the servo off board and that has fixed alot of crashing issues.

I have the APM2 and receiver removed from the rover and power by USB and its still crashing selecting auto.

Im curious about the ch5 input changing mode when it should be ch8, has the code changed or is there another flag or function that im missing? I have verified that ch5 is working correctly in manual and aquire mode with being able to store and deleted WP's from the APM2

Any more ideas?

Chris

Chris: Are you sure about that In 5 mode thing? Mine is connected like the diagram: RC CH5 goes to APM IN8. Works fine... I'm using APM 1, but I don't think that should make a difference.

Chris: Mine is connected RC CH5 (3 position sw) to APM2 IN5, if i connect to APM2 IN8 i get no change in mode.

Chris: I'll try one of the older versions to see if i get the same result

Chris: Did you select APM 2 as the board in the config.h file: 

#define CONFIG_APM_HARDWARE APM_HARDWARE_APM2

3D Robotics Comment by Chris Anderson on July 11, 2012 at 10:40pm

Also, LITE should be disabled for APM 2:

#define LITE  DISABLED    // if LITE is ENABLED, you may use an APM1280 or APM2560 CPU only (IMU less) with a GPS MT3329

// if LITE is DISABLED, this is for a full APM v1 (Oilpan + GPS MT3329 + Magnetometer HMC5883L) or APM v2

I'm pretty sure I set those variables but it does hurt to check and reload

Could somebody help me getting my xbees to work? I have downloaded the latest Firmware 2.2 and uploaded to my apm2. in the code I have set it to APM2 and LITE DISABLED. But I do not get a xbee connection. What do I have to set, that the xbees will work? I have a second APM2 with the Arduplane Firmware on it. There I can connec the xbee to and it starts working... So shoulb be a code issue?!

cheers Boris

Boris: Make sure you have the Port 3 speed set to 57,400 in the code. 

Developer Comment by Andreas M. Antonopoulos on July 12, 2012 at 8:59am

I believe Chris meant 57,600

 

Look for SERIAL3_BAUD
