TransferData Question

[imecar-github]

Hi. I have a question about TransferData with blocksize 128. I want to send data from client to server 128 byte packets. But I could not manage to use kISO14229_CLIENT_CALLBACK_PENDING and kISO14229_CLIENT_CALLBACK_DONE. How can I handle 128 byte packet is sent? I want to see positive TransferData response but I could not see.

I'm using SD CARD with FATFS. But TransferDataStream is using iostream. I could not use TransferDataStream with FATFS.

My first question is, Is there any other else TransferData function with blocksize 128? Second question is, how can I use TransferDataStream with FATFS ?

Edit1: I am using iso14229ClientSequenceRunBlocking.

Please attach code

how can I use TransferDataStream with FATFS ?

You can retarget the stdio.h functions either at the linker level (defining your own fread, etc) or at the compiler level (compile iso14229 with -Dfread=f_read and it will directly use your FATFS functions)

` if(fileEOF == false) { if(file_counter > fileFileInformation.fileSize) { fileEOF = true; return kISO14229_CLIENT_CALLBACK_DONE; } file_willRet = 128; if((fileFileInformation.fileSize - file_counter) < 128 ) { file_willRet = fileFileInformation.fileSize-file_counter; lastBlock = true; } TransferData(client, file_blockSizeCounter, 130, fileFileInformation.buffer + file_counter, file_willRet); if(!lastBlock) { if(20 == file_canMessageCounter) { file_blockSizeCounter = file_blockSizeCounter + 1; if(file_blockSizeCounter == 256) { file_blockSizeCounter = 0; } file_counter+= 128; file_canMessageCounter = 0; g.serverRecvQueueIdx = 0; } } else { if((((fileFileInformation.fileSize - file_counter) / 7) + 1) == file_canMessageCounter) { file_blockSizeCounter = file_blockSizeCounter + 1; if(file_blockSizeCounter == 256) { file_blockSizeCounter = 0; } file_counter+= (fileFileInformation.fileSize - file_counter); file_canMessageCounter = 0; g.serverRecvQueueIdx = 0; fileEOF= true; }

               }
                file_canMessageCounter++;
                HAL_Delay(5);
                return kISO14229_CLIENT_CALLBACK_PENDING;
        }
        else
        {
             return kISO14229_CLIENT_CALLBACK_DONE;
        }

        return kISO14229_CLIENT_CALLBACK_DONE;`

I write something like this, but It does not work every file. Could you provide me an algorithm ?`

Edit:

`if (file_driverEOF == false) { if (file_counter > fileFileInformation.fileSize) { file_driverEOF = true;

    }
    file_willRet = 128;
    if ((fileFileInformation.fileSize - file_counter) < 128) {
        file_willRet = fileFileInformation.fileSize - file_counter;
    }

    TransferData(client, file_blockSizeCounter & 0xFF,
            file_willRet + 2,
            fileFileInformation.buffer + file_counter,
            file_willRet);
    if(client->state == kRequestStateSent)
    {
         file_counter += 128;
            file_canMessageCounter = 0;
            file_blockSizeCounter++;
            g.serverRecvQueueIdx = 0;
    }

    HAL_Delay(5);
    return kISO14229_CLIENT_CALLBACK_PENDING;
}

return kISO14229_CLIENT_CALLBACK_DONE;

I just tried this code and everything seems fine!

OK. I'm closing this issue.
