Prerequisite:
FT4222_I2CSlave_Init
Example:
FT_HANDLE ftHandle = NULL;
FT_STATUS ftStatus;
FT4222_STATUS ft4222Status;
ftStatus = FT_Open(0, &ftHandle);
if (FT_OK != ftStatus)
{
// open failed
return;
}
// initial i2c slave
ft4222Status = FT4222_I2CSlave_Init(ftHandle);
if (FT4222_OK != ft4222Status)
{
// i2c slave init failed
return;
}
ft4222Status = FT4222_I2CSlave_SetClockStretch(ftHandle, TRUE);
if (FT4222_OK != ft4222Status)
{
// set clock stretch failed
return;
}
uint8 sent_data[] = {0x1A, 0x2B, 0x3C, 0x4D};
uint16 sizeTransferred = 0;
ft4222Status = FT4222_I2CSlave_Write(ftHandle, sent_data, sizeof(sent_data),
&sizeTransferred);
if (FT4222_OK != ft4222Status)
