Missing definition ReadSMBusByteArray and WriteSMBUsByteArray and WriteSMBuSCommand

Hi,

so i translate vb SaveDataFlashImageToFile in c code, the SMBus function used is correct or not ? thanks in advance for your help

Function SaveDataFlashImageToFile(sFileName As String) As Long
Dim iNumberOfRows As Integer
Dim lError As Long
Dim yRowData(32) As Byte
Dim yDataFlashImage(&H700) As Byte
Dim iRow As Integer
Dim iIndex As Integer
Dim iLen As Integer
Dim iFileNumber As Integer
'// FOR CLARITY, WITHOUT USING CONSTANTS
'// 0x700 is the data flash size.
0x700 \ 32 = 56 rows
iNumberOfRows = &H700 \ 32
'// PUT DEVICE INTO ROM MODE
lError = WriteSMBusInteger(&H0, &HF00)
DoDelay 0.01
'// READ THE DATA FLASH, ROW BY ROW
For iRow = 0 To iNumberOfRows - 1
'// Set the address for the row. &H9 (0x09) is the ROM mode command.
'// 0x200 is the row number where data flash starts.
'// Multiplication by 32 gives us the actual physical address where each row starts
lError = WriteSMBusInteger(&H9, (&H200 + iRow) * 32)
'// Read the row. &HC (0x0c) is the ROM mode command.
lError = ReadSMBusByteArray(&HC, yRowData, iLen)
'//Copy this row into its place in a big byte array
For iIndex = 0 To 32 - 1
yDataFlashImage((iRow * 32) + iIndex) = yRowData(iIndex)
Next iIndex
Next iRow
'// WRITE DATA FLASH IMAGE TO FILE
iFileNumber = FreeFile
Open sFileName For Binary Access Write As #iFileNumber
Put #iFileNumber, , yDataFlashImage
Close #iFileNumber
'// EXECUTE GAS GAUGE PROGRAM
lError = WriteSMBusCommand(&H8)
End Function

VB to C code with SMBus Functions, what you think about that it is right or absoluty wrong ?

#include <stdlib.h>
#include <stdio.h>

long lError;
int iFileNumber, iNumberOfRows, iRow, iIndex;
bytes[] yRowData = new byte[32];
bytes[] yDataFlashImage = new byte[1792]; // 0x700

#define ADRESSE_SLAVE 0xXX

FILE* fichier = NULL;

// 0x700 taille diviser par 32
iNumberOfRows = 56;
// mettre le bq20z655 en mode ROM
lError = i2c_smbus_write_word_data(0x00,0x0F00);
// pause à vérifier
sleep(10);
// lecture de la flash

for(iRow=0;iRow<iNumberOfRows;iRow+1)
{
	// 0x09 rom mod command
	// 0x200 strat row flash
	// x32 the next row 
	lError = i2c_smbus_write_word_data(ADRESSE_SLAVE, 0x09, (0x200+iRow)*32);
	
	// 0x0c rom mod command
	lError = i2c_smbus_read_i2c_block_data(ADRESSE_SLAVE, 0x0C, yRowData, iLen);
	
	for(iIndex=0; iIndex<32; iIndex+1)
	{
	yDataFlashImage((iRow*32)+iIndex) = yRowData(iIndex);
	}	
}

fichier = fopen("data_flash.txt", "w");

if(fichier != NULL)
{
	fputs(yDataFlashImage,fichier);
	fclose(ficher);
}

lError = i2c_smbus_write_word_data(ADRESSE_SLAVE,0x00,0x0008);

I use a Raspberry PI to read and wirte the bq20z655 but the target device on SMBus is 0x48 and 0x0b but not 0x16.

What's happen, can you explain why i can't see the 0x16 address ?

Thank's you in advance
