Well, that may be not i2c but gpio, for example, we have received the
following code for key scanning from Gotview www.gotview.ru We failed to
make it work mostly due to the lack of testers. As I see we need to
reset gpio pin to allow key scan.


BYTE ReadRemoteDataFromGPIO34(void)
{

#define RESETADDR 15

BYTE ScanCode=0xFF;
HRESULT hr;
long isnotpressed=0;

if (pGPIO)
{

hr=pGPIO->Reset();
pGPIO->WriteGPIO(RESETADDR,1);
pGPIO->WriteGPIO(RESETADDR,0);

Sleep(25);

if(bSaa7135)
{
isnotpressed=!ReadGPIO(4);
}
else
{
isnotpressed=ReadGPIO(14);
}

if (isnotpressed)
{
ScanCode = 0xFF;
}
else
{
if(bSaa7135)
{

BYTE mask, kvalue, gpion;
int i;
BYTE Result = 255;

if (pGPIO)
{
mask = 0;
kvalue = 0;
for( i=9;i>=2;i--)
{
if (i == 3)continue;
if (i == 4)continue;
if (i == 5)continue;
gpion = ReadGPIO(i);
Sleep(25);
kvalue = kvalue | gpion << mask;
mask++;
}
gpion = ReadGPIO(3);
kvalue = kvalue | gpion << mask;
}
ScanCode = kvalue;
}
else
{
ScanCode = GetGPIOMaskValue(8,13);
}

if(lastcode==ScanCode)presscounter++;
else presscounter=0;
}

lastcode=ScanCode;
hr=pGPIO->Reset();

pGPIO->WriteGPIO(RESETADDR,1);
pGPIO->WriteGPIO(RESETADDR,0);

}

if(bSaa7135)
{

return F35to34(ScanCode)-0x80;
}

return ScanCode;

}
