Hello Mr Roberto ,

i try your structure and it work thank you so much for your help also i pass -1 in the  in OutputQueueSize parameter 

this my function i think i have a problem with the buffer always show the same value any suggestions please

Of course you receive only the last formatted string! A function can return only one value and the way your code is written RES string is overwritten each time.

You could modify your function to receive three independent strings and format the output message in one or the other. The caller must use the three strings as input/output parameters.

i need the function to return only the last frame readed 

i do strcpy (RES,msg) only with the last one the others just msg to show them  to verify 

this is the function i need only to explore the last frame readed

A few hints to help you debug this situation.

  • You always read in a variable 'response' which is not defined in the function: is this a global variable? Can it be overwritten elsewhere in the program? Can it be locked by other functions so that ComRd fails and you terminate interpreting an old message?
  • What if you don't use memcpy and elaborate directly 'response' buffer instead?
  • Add some error checking at least on ComRd calls, just to be sure there isn't any problem in the communication
  • You don't place any delay between writes and reads: does the device responds immediately? Doesn't it need some time to elaborate the commands received?
  • Is there a reason to use a series of ComWrtByte instead of a single ComWrt?

These are only common-sense suggestions, as I don't know the device you are speaking to. Communications with external devices is not always a simple task as it involves two independent devices to sync together.

Thank you for your help 

i trying to communicate with an PSA automobile display using CAN box AXIA and USB/ RS232 adapter
- yes Reponse it's a global variable and it''s overwritten in every functions
- i delete memcpy and i'm manipulate the 'Reponse' directly
- the device respond immediatly and i'm not using any delay between write and read
my problem start from the PSA_MODE function all the previous  functions work so well
this the whole code and the functions that i'm trying to developp and the last result that i getresult.PNG

Rif.: create a function in CVI

‎06-07-2017 12:31 AM

Ahmed,

I see little of my suggestions in that code and this last PSA_MODE function does not even return a string so please keep calm, revise this entire discussion, implement all suggestions and try again!

 

With this I mean:

  • OpenComConfig called with -1. By the way, you do not need to pass the device name when you open the port, simply pass an empty string and let the driver choose by itself. See the help for that function
  • Output message buffer need to be unsigned in order to correctly format high-value bytes
  • Clear 'Response' before reading: memset (Response, 0, 20);
  • Add error checking to ComRd! You must ask yourself (and in the code): are there any communication errors? If not, am I receiving anything? If yes, am I receiving the correct number of bytes? Only after all answers are satisfactory you can proceed to check received response

Finally, do not publish all the code! You are wasting forum resources with plenty of unnecessary code and screenshots that really add nothing to the discussion.

Rif.: create a function in CVI

‎06-07-2017 07:30 PM

Hello Mr Roberto
thank you for your help
i implement all the suggestions , this structure work with previous functions like init can, i don't have any problem with communication my problem is i can't get the right received response especially when i send this frame i receive null bytes and when i delete memset (Reponse, 0, 20); i receive the same previous response
CAN :->88 55 03 24 FA
CAN6 :<-88 55 09 40 06 65 03 02 50 03 A5 :OK
as you can see in the capture result iget the right response in previous sended frame 



result.PNGthis my try any suggestions please 

	char*  PSA_MODE  (int Port_CAN , char*RES)

Rif.: create a function in CVI

Apparently your device does no respond or returns a string of NULLs, which seems strange to me. I cannot comment on this as I don't know what the device is expected to respond and within which time.

 

But you are still missing to check the result of ComRd! Go and check it before continuing to argue on the code: you cannot be sure of what's happening as far as you don't check it!

this what the device  is expected to respond CAN6 :<-88 55 09 40 06 65 03 02 50 03 A5 

and it respond immediately i verify this with other development environment from where i get  these frames 

i cannot check ComRd with breakpoint i get error always

how can i check response in CVI not in Labview after i build the dll like i do ?

Which error? Do I have to guess it out of my gazing ball?

And without thinking to breakpoints, why not saving the result to a variable and printf-ing it on output?
