Ardupilot 2.0.1 Released

Main changes:-Solved compatibility issue with Arduino IDE 14 and 15, (thanks very much Arduino Mega).-Z Sensor support (extremely recommended, otherwise you will fly strange).-An small Ground Station based in Labview to play with ;-)...And can be donwloaded from here.The problem with the Ground Station is that i can't compile it, but you can run it if you have Labview installed. Later i will release the EXE.It includes a better virtual horizon and displays Speed, Altitude, Climb rate, Heading, Bearing and show the aircraft position in real time using Google Earth.What you need:-Any radio modem (XBEE) running at 57600bps.-Labview 8.6 installed.-Run the file "groundtest.vi".-Select the port number, then click open and enjoy!(You can try it with the FTDI cable if you don't have radio modem).Note: This ground station is same I'm using right now to debug the new ArduPilot firmware 2.1.Ground Station download click here.[UPDATE: The Ground Station for Labview 8.5 please Click here]Be ready for the next release of ArduPilot firmware, the version 2.1, that will include:-Diagonal X Sensors.-Throttle Control-AirSpeed Sensor Support[Warning: You need Arduino 0015 or higher in order to use this firmware]

  • When i conect the GPS and the FTDI cable, sometimes the telemetry information stops. The FTDI cable are interfering with the comunication? Only a RS232 or a Xbee can be used?
  • Just one last question in the future version of ArduPilot (2.X), there will be possible to transfer the flight plan via the Xbee wireless connection?

  • I had stayed a minimum speed of around 20 kilometers per hour ....
    It evolves quickly and well ... perfect!!!
    Thanks Jordi
    Thank you for saying hello to the Sparkfun webcam ;-))

    Larry,
    Well is working perfect around 8km/s, but the new version has 33% more resolution, so would be better... ;-)

    @Graham. The reasons we didn't catch that is that we're flying 2.1 and 2.2, and it's fixed in both of those. I think we just accidentally released a bug in the preliminary public version. We'll be releasing new code this week.
  • Chris, Jordi,
    What speed is the minimum that can measure the pitot tube?
    The measurement of low speeds is it reliable below 20km/h (12 miles per hour) ?

    @Graham. I think that's right--good catch. I'm just double-checking with Jordi. Weirdly it compiles okay for me, but the logic does seem wrong.

    I get the following error when compiling or uploading v2.0.1:
    "error: 'catch_analogs' was not declared in this scope"

    {
    catch_analogs(); //Reading infrared...
    }

    I changed 'catch_analogs()' to 'catch_IRs()' on the Infrared tab, it compiles now but is that right?
  • Thanks Chris

    @Larry. The pressure sensor is dual (differential). You can use either a dual-tube pitot like you showed, or just a single-tube pitot with the second sensor port getting ambient pressure from the cockpit.
