Hello, I am using V1.4 APM but can't seem to get the Arduino to upload to the board.  I see it as com 8 but when I choose to upload it compiles then fails after a long time out.  I am lost, I feel lie I am missing some instructions but do not know where to go next.  I have been trying this for a week now and seem that I am no closer than I was the first day.  Please help....  Thanks.

jesse,

Are you communicating directly with the APM1 or through the USB connector on the Oilpan? If you are communicating directly with the APM1 are you using the correct FTDI cable and is it connected to the APM1 header correctly? Also, if you are using a FTDI cable, do you have the RST reset box checked in the COM8 port properties?

Too bad you live clear down at Corpus Christi as I could have come over and helped you out, but I live a ways away in Garland!

Just a thought.

Regards,

TCIII

JLN: ArduRover 2.16 is giving a couple of compile errors with the new MAVLink 1.0 libraries: 

APMrover2.cpp: In function 'void send_heartbeat(mavlink_channel_t)':
GCS_Mavlink:74: error: 'MAV_MODE_FLAG_LEARNING_ENABLED' was not declared in this scope
GCS_Mavlink:94: error: 'MAV_MODE_FLAG_LEARNING_ENABLED' was not declared in this scope
APMrover2.cpp: In function 'void init_ardupilot()':
system:234: error: 'MAV_GROUND' was not declared in this scope

hey, is anybody willing to advise me as to how to fix my rover/car?

it ran into a piano and the RC receiver/controller circuits are non-functional now. (it will not respond to signals)

the motors are fine, it's just the RC circuits. I've been thinking of just adding a control chip and ignoring the remote part of it.

sorry of this is a dumb question but I am after a bit of clarification. You said that v1 light works with the apm v1 1280. did you also test v1 light with the magometer? And did you also test it with the camera? Thanks in advance.

@Chris,

Are you using a newer library than comes with APMrover2?

Chris, Garland just up the road.lol.  I am plugging in to the IMU shield(Blue Board).  I made the changes to the COM port but still no go.  Does it matter what is selected on the Tools/Programmer Menu?

jesse,

If you have an FTDI cable handy, I would try communicating with the APM1 with that cable to ensure that the APM1 is functional. I assume that you have selected the correct processor in the tool drop down menu? Is your board a 1280 or a 2560? Also, does your USB port have enough capacity to handle the APM/Oilpan combination. I assume that the power light on the APM1 is ON when you have the module plugged into the USB cable. Is the USB cable good to go?

Regards,

TCIII

I ordered a FTDI cable so I will see if that works.  I am able the use APM Planner without any issues, so I'm sure my system is ok.  Thanks for your help I'll let you know once I get the FTDI cable.

A few more lessons from testing today: 

 

1) The new 3DR uBlox GPS, which will be coming out in a few weeks, is 1000% better on ArduRover than the original MTK. Night and day! Totally locked in and 1m accuracy.

 

2) Warning for those using the magnetometer with ArduRover. For some reason, the default setting of its orientation in the code (APM_Config_Rover) is  #define MAG_ORIENTATION AP_COMPASS_COMPONENTS_UP_PINS_FORWARD.

 

This is upside down for most people (the default setting for all other Ardu* projects is Components Down). So change that line to:  #define MAG_ORIENTATION AP_COMPASS_COMPONENTS_DOWN_PINS_FORWARD

We'll be posting a fuller tutorial soon.
