Re : Interfacing Ardupilotmega with Labview with Mavlink Protocol

[daniel2222]

Sorry. i still Work on another project. What Kind of Terminal sw do u use?

and ive Some problems like u With different chipsets on rs232 converter.
Maybe try another on with another chipset

[scstefa]

i solved my problem...

it was still a missing converter on hardware side.

now i use a tll-rs232 converter (SparkFun RS232 Shifter SMD) - the UART port uses other voltage levels

to view the data on the laptop, i connect the PX4FMU first to the tll-rs232 and then to the rs232-usb converter.

Hi,i want to read data from ardupilot by using labview,so  i use the exmple in the disscusion ,but its give me error in mavlink crc.vi    the message showing is : 
""  Error 7 occurred at Call Library Function Node in mavlink CRC.vi->initialize.vi->example usage.vi  ""    thanks for help

achrafbak, the file "mavlink_crc.dll" needs to be in the same folder as the .llb file.  That error is saying that the library call node can not find the dll file.

thanks       Shadowclaw           for your help,i move the following file,but it still give me error : 

"Error 12 occurred at Call Library Function Node in mavlink CRC.vi->initialize.vi->example usage.vi"

[Shadowclaw]

it looks like error 12 means that architecture is wrong.  The dll is a 32bit dll which means that it will only work with 32bit labview.

thanks, i have windows 7 64bit,i will test it in 32 bit and report the result,

thanks again

[Shadowclaw]

whether it is 64bit or 32bit windows should not matter (I wrote the dll on a 64bit machine).  What matters is whether or not you installed the 32bit or 64bit version of labview.  I would recommand installing the 32bit version of labview even if you have 64bit Windows.  You get very few benefits out of the 64bit version of labview and in a most cases you will never notice a different between the two.

How do I use this software? when I open it in labview it is a whole bunch of file that seem to do different things, How do I make them all work in one interface?

Thankyou.

[Shadowclaw]

Tryingtolearn, if you are refering to my mavlink software there should be an example_usage.vi in the llb that has some comments about what pieces do what.
