Setting these registers to the desired values would be part of a normal initialization or setup procedure. In addition, to maximize the performance of the device under various conditions, the integration time and gain may be changed often during operation. The following pseudo code illustrates a procedure for setting up the Timing Register for various options: // Set up Timing Register //Low Gain (1x), integration time of 402ms (default value) Address = 0x39 Command = 0x81 Data = 0x02 WriteByte (Address, Command, Data) //Low Gain (1x), integration time of 101ms Data = 0x01 WriteByte (Address, Command, Data) //Low Gain (1x), integration time of 13.7ms Data = 0x00 WriteByte (Address, Command, Data) //High Gain (16x), integration time of 101ms Data = 0x11 WriteByte (Address, Command, Data) //Read data registers (see Basic Operation example) //Perform Manual Integration //Set up for manual integration with Gain of 1x Data = 0x03 //Set manual integration mode – device stops converting WriteByte (Address, Command, Data) //Begin integration period Data = 0x0B WriteByte (Address, Command, Data) //Integrate for 50ms Sleep (50) //Wait for 50ms //Stop integrating Data = 0x03 WriteByte (Address, Command, Data) //Read data registers (see Basic Operation example) |
