@Alan,

Where have you been? I think that the move to the Hardware Abstraction Layer was pretty well advertised on the forum. The move to the HAL requires a special version of the Arduino IDE 1.0.3 that includes a "ArduPilot" menu in the IDE header that allows the user to identify the flavor of the APM that they are trying to program. Without the modified IDE, post HAL versions of the ArduRover2 v2.30 alpha code will not compile and will give compiler errors when using the stock IDE 1.0.3.

Regards,

TCIII

@Thomas,

Any idea why a special version of 1.03 needs to be used?  I have both, one for ros_arduino_bridge, and one for APM.  They work, although it's always a chore to get the libraries in the right place.

@Bot_Thoughts

The APMs have an I2C port that is presently used for reading the compass.

@saba,

You have to use a specially modified version of Arduino IDE 1.0.3 that can be found here: http://code.google.com/p/ardupilot-mega/downloads/detail?name=ArduP... 

When you start the IDE you must select the model of the APM you are using from the menu in the "ArduPilot" menu in the IDE header. Then restart the IDE for the selection to take affect.

Regards,

i downloaded the software ArduRover_v230_firmware_20120222 zip folder. but i am getting the attached compilation error. pl guide for the correct software version. thanks in advance.

@Vijay -- I second that recommendation. It's boosted SNR by 10dB on both my SiRFIII and Venus GPSs.

@KM6VV -- cool! I wanted a tiny form factor that would plug in right next to the sensor with a dedicated ADC and careful PCB layout for better performance (yet to be verified, but I think it'll be good). Prototype Rev0.1 pictured at right.

@ben -- when your robot is bookin' along at > 25mph trying not to slam into 55 gal barrels and lose the race, ... well... gotta have that obstacle detection :D  But I do have a safety cutover circuit where I have manual control an instant after I turn it on.

if u just want obstacle holy crap stop button just get normally closed sensor and wire it up to ur ch3 output to shutdown throttle.

A similar "adapter" could be made up for SRF08 rangefinders.  I run six off of a PIC.

I had bad experiences with the MediaTek GPS I had. I love the Venus 638FLPX I am using now. I haven't tried the uBlox yet but have a test one that I keep meaning to play with.
