coTfsSDOBlockUpload (Level 2)

Valid for: CANoe DE • CANoe:lite DE • CANoe4SW DE

​
Function Syntax

long coTfsSDOBlockUpload( dword index, dword subIndex, dword useCrc, dword outCrcUsed[1] ); // form 1
long coTfsSDOBlockUpload( dword index, dword subIndex, dword useCrc, dword outSize[1], byte outValueBuf[], dword valueBufSize, dword outCrcUsed[1] ); // form 2

​
Description

This function executes a complete SDO block upload. The block transfer must be supported by the receiver. After a successful upload, the data received can be called up with the command coTfsSDOGetUploadData. (form 1) Alternatively, the received data can be used as parameters directly and set whether the block transfer is executed with or without CRC support. (form 2) A fallback to segmented transfer is not supported.

​
Parameters

  • index: Object index
  • subIndex: Object subindex
  • useCrc: Enables use of CRC check.
  • outSize[]: Data size of the received data.
  • outValueBuf[]: Data field with the received data.
  • valueBufSize: Reception buffer size in byte of outValueBuf.
  • outCrcUsed[1]: The passed CRC.

    write("data %i = 0x%X",i,pReceiveData[i]);
  } // for
