Below is the program section taken from the WifiAppDemo. ( I will post the full source code later in the wiki page)

tmpH is the MSB and tmpL is the LSB of the temperature or humidity reading from the device, if current pClientProp->i2ccmdstep is under step3, the tmpvalue is humidity reading, or else is the temperature reading. The calculation is in the if-else loop.


                tmpvalue=(double)(256*tmpH)+tmpL;
                if (pClientProp->i2ccmdstep==step3)
                {
                    //Humidity reading
                    pDrvHumidity->humidity=(float)(125*tmpvalue/65536)-6;
                    DMgr_RecNextStep(pClientProp,&DrvHumidity_refresh);
                }
                else {
                    //temperature reading
                    pDrvHumidity->temperature=(float)(175.72*tmpvalue/65536)-46.8;
                    pDrvHumidity->dataready=1;
                    DMgr_SendDone(pClientProp);
                }

Just uploaded the full source code for the Wifi Remote I2c Server and the Demo App. The link in the wiki are,

Thanks for answer. But I already find solution...)))
Bty, another info might be helpful is that the Temperature/Humidity sensor will do a I2c clock stretching when the host request to read the reading from the sensor. This is because the sensor require about 100~200ms to convert the reading to digital data. If you did not implement clock stretching in you I2c communication, you will receive the wrong reading.

Hi. I have problem with my I2C POT board. When i set jumper to 3.3V. I2C POT board still give 5V. I try set all (two) jumpers to 3.3V, power for i2c still 5 volts....
@Artyom, Just PM you on the I2c POT Board problem.
