IPort Programming

Kimson

I downloaded a IPort Program from www.iportmusic.com for controling the Iport FS-4.
But it can't compile, could anybody know what happen and how to resolve this problem?

NMarkRoberts

It compiles fine for me.

I extracted al of the zipped files into a fresh folder, launched NetLinx Studio 2.5.0.163, opened the .APW file and clicked on [Build Active System].

Kimson

thanks for your testing.
I had followed your step to do it again, but it still can't work.

the error as below:

Here is the tree of workspace

UnicodeLib relies on the availability of a bunch of routines called _WC_* which are to be found in the library include NetLinx.axi. My copy is in

C:\Program Files\Common Files\AMXShare\AXIs

and that location is set in NS2 in Settings/Preferences/NetLinx

thanks for your reply!~

i had checked the UnicodeLib is here. The path of this file is same as your's one.
but also can't compile.

NMarkRoberts

You need NetLinx.axi as well as the UniCode library.

NetLinx.axi also is here.
Thanks.

Just a quick note about control of iPort from AMX: use the NetLinx module not the Duet one. The NetLinx module works great with a nice layout and manages well international characters and stuffs like that

Vince

I'd second that. I had some problems with the Duet module but the Netlinx one worked a lot better.

Anyone seen the new RS-232 board for the iPort that lets you control the video side as well as audio?

NMarkRoberts

Try looking in NetLinx.axi to see if the _WC_* routines are there.

Thanks!
After enable the _WC_* routines in NetLinx.axi, i can compile the program.

Kimson

To All:
Thanks for your help!
Now i got another question about the RS-232 command for iPort.
I don't how is the command and how to make a checksum code.
Could anyone can give me some advice?

NMarkRoberts

Almost all AMX modules offer a PASSTHRU option so if you have the module installed and send it the command string it will add the CRC for you:

send_command vIportComms, "'PASSTHRU-',commandstring"

Alternatively, if you read the manual it says

"2's complement of the sum of all bytes excluding the start character and the checksum"

here is the relevant code, untested. To be honest I'm not sure about the 2's complement calculation and others may have a neater implementation.

define_function char iPortChecksum(
  char sArgText[])
{               
stack_var integer nMyChecksum
stack_var char    nMyChar
stack_var integer nMyPointer

nMyChecksum = 0 (* Habit *)

(* Add all characters excluding the first one *)
for (nMyPointer = 2; nMyPointer <= length_string(sArgText); nMyPointer++)
  {
  nMyChecksum = nMyChecksum + sArgText[nMyPointer]
  }         

(* Just the low order byte *)
nMyChar = type_cast(nMyChecksum BAND $FF)

(* Two's complement *)
nMyChar = type_cast(256 - nMyChar + 1)    

return nMyChar;
}

Probably a year ago I talked with someone from tech support you said the Duet Module was buggy and really shouldn't be used and to use the Netlinxs version instead.

One would think that it would have been fixed by now but then again with all the module they write with bugs in them this one would be of a low priority. But that makes you wonder why they don't just pull it until it's fixed leaving the Netilinxs module as the only choice. Are they sadistic and want us to suffer and waste are time and resources? Hmmm.. makes you wonder!

NMarkRoberts

Looking in inConcert I could only find the Duet module with no source code, no documentation of the protocol and no NetLinx module. Is it hidden somewhere?

vincen

Unhappy it's not avalaible through website. Only way is to ask tech support in Dallas. You'll find attached most recent version I have that works pretty nice

Hope it helps you

Here?s the published protocol posted at iportmusic.com. It?s a pretty cool device to integrate with. I believe future revs will allow us to grab cover art.

Have fun! I sure did?still am.

iPort Support

With the install of the most recent version of Visual Architect v1.2 came a new Netlinx.axi file. The WC options have been commented out in this version. I have attached the new Netlinx.axi file that has the WC options commented in if needed.

Version 2.01 of the Netlinx module is on the Inconcert section of the AMX website. I am working to get the readme file before the end of April plus a new version that will support the newer Video supported version of the iPort SW5 and FS5. I have a beta of this version if you need it - it works but we need to improve it before posting it.

The Duet version will be updated after the API for these type of devices is improved (MAX, Fireball, Request, etc.).

Here is the Checksum from the iPort COMM file:

DEFINE_FUNCTION INTEGER Calc_Chksum (char cmd[]) // Calculate Checksum
{
   stack_var integer i
   stack_Var integer checksum
   
   checksum = 0
   
   // Sum up all the elements of the command
   for (i = 1; i <= length_array(cmd); i++)
   {
       checksum = checksum + cmd[i]
   }
 
   // Subtract 1 from the sum
   checksum--

    // Calculate the checksum
   checksum = $FF - checksum 
  
   return checksum
}

It will be interesting to see the cover art functionality over 232. From what I understand it will only show cover art for the current playing song like the iPod does.
