Now I must read sensor(MT9M112)'s parameter via i2c bus,
this sequence is :
1.send Slave Device addr and data addr,
2.read data.
and as follows,it confuse me.
=======================================================================

PSP_I2cRequest readBuf;
size_t size;
char buffer;
int status;
readBuf.i2cTrans.buffer = (Uint8 *)&buffer;
readBuf.i2cTrans.bufLen = 1;
readBuf.i2cTrans.flags = PSP_I2C_DEFAULT_READ;
readBuf.i2cTrans.param = NULL;
readBuf.i2cTrans.slaveAddr = 0x50;
readBuf.timeout = SYS_FOREVER;
size = 1;
status = GIO_read(i2cHandle, &readBuf, &size);
=============================================================
in this process,which part I can input the "data addr"?
and the GIO_read() function can read from eeprom or other sensor via i2c bus?
thanks
