Si705

Hi, I'm trying to read the temperature from Si705. I have connectiong to the sensor, as I have tested it, when I read the firmware-version using the measurement-process described in this pdf (https://www.silabs.com/documents/public/data-sheets/Si7050-1-3-4-5-A20.pdf) page 16. However, when I try to read the temperature, my output ends up being 0, 0. As of now my code is this:

uint8_t cmd;

uint8_t data[2];

uint16_t degrees;

cmd = Temp_H;
