UDS_SetValue DLL

Postby sjash » Thu 10. Jan 2019, 23:28

Hey,

I've been trying to set value on the pcan usb device using the UDS_SetValue dll api. I'm unable to set the values. I get an exception which is as below.

Exception 0xc0000005 0x0 0x1 0x7ffa616767fc
PC=0x7ffa616767fc

syscall.Syscall6(0x7ffa61702920, 0x4, 0x51, 0xe2, 0x1, 0x4, 0x0, 0x0, 0x0, 0x0, ...)

Please could someone here help me resolve this problem.

Also when using PUDS_PARAM_MAPPING_ADD and passing TPUDSMsg struct as value I get invalid parameters.

Hello,

The exception don't offer any useful information. Please first check that you are using the last versions of the APIs. If the problem persists, then provide more information about your case:
  • Which program language are you using?
  • Operating system used
  • Snippet of code where you are seeing the crash
Best regards,
Keneth

I'm using golang to build an api.
OS : windows 10
PCAN-UDS API Version : 1.3.1.30

I get this error when trying to mapp
Code: Select all

st, _ := u.SetValue(uds.PudsUsbBus1, uds.PudsParamMappingAdd, &request, unsafe.Sizeof(&request))
func (u UDS) SetValue(CanChannel TPUDSCANHandle, Parameter TPUDSParameter, Message *TPUDSMsg, BufferLength uintptr) (TPUDSStatus, error) {
   proc, err := u.TPUDS.FindProc("UDS_SetValue")
   checkError(err)
   res, _, err := proc.Call(uintptr(CanChannel), uintptr(Parameter), uintptr(unsafe.Pointer(Message)), BufferLength)
   return TPUDSStatus(res), err
}


This returns a TPUDSStatus of 8 which is Invalid Parameters

I go that exception dump when trying to set the param debug to true.

Do have a PCAN-UDS api support for linux?

This is the structure of my TPUDSMsg

Code: Select all
//TPUDSMsg Defines a CAN UDS message. The members of this structure are sequentially byte aligned
type TPUDSMsg struct {
   // Network Addressing Information
   NETADDRINFO TPUDSNetAddrInfo
   // Result status of the network communication
   RESULT TPUDSResult
   //States wether Positive Response Message should be suppressed
   NoPositveResponseMsg byte
   // Data Length of the message
   Len uint
   // Type of UDS Message
   MsgType TPUDSMessageType
   // Represents the buffer containing the data of this message
   Data DATA
}

// DATA is the data structure of the TPUDSMsg
type DATA struct {
   RAW []byte
}


UDS_GetValue and UDS_SetValue works fine for all the other Parameters except for UDS_PARAM_MAPPING_ADD

Hello,

sorry but we don't support this programming language. Refer to a Go forum instead, since this problem is not related to the API but to the DLL porting.

No, only PCAN-Basic is actually available for linux. The high layer APIs are only available on Windows.
