PCAN-UDS API Version-2.3.0.256
When I used UDSApi.AddMapping_2013 function to mapping CANID(request 0X784,Response 0x 78C) and used the sample (UDS specification page 166 with C# )
and then send the uds diagnostic session control message with function UDSApi.SvcDiagnosticSessionControl_2013(sample from page260)
and after running the code ,initialization and mapping seems successful ,but arose error(PUDS_STATUS_SERVICE_TX_ERROR) when sent the diagnostic session message
Below is my code
Code: Select all
private void Init_Click(object sender, EventArgs e)
{
StringBuilder buffer = new StringBuilder(BUFFER_SIZE);
stsResult = UDSApi.GetValue_2013(cantp_handle.PCANTP_HANDLE_NONEBUS, uds_parameter.PUDS_PARAMETER_API_VERSION, buffer, BUFFER_SIZE);
MessageBox.Show("PCAN-UDS API Version - " + buffer.ToString());
stsResult = UDSApi.Initialize_2013(m_clientHandle, m_baudrate, (cantp_hwtype)0, 0, 0);
if(!UDSApi.StatusIsOk_2013(stsResult))
{
MessageBox.Show(UDS_STATUS_OK_KO(stsResult));
}
PUDS_SetRequestResponse_CANID();
}
private void ReadMsg_Click(object sender, EventArgs e)
