APPLICATION INFORMATION: SOFTWARE

Configuring the Timing Register

The command, timing, and control registers are initialized to default values on power up. 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 12ms (default value)

Address = 0x39

Command = 0x81

//Timing Register

Data = 0x02

WriteByte(Address, Command, Data)

//Low Gain (1x), integration time of 101ms

Command = 0x81

//Timing Register

Data = 0x01

WriteByte(Address, Command, Data)

//Low Gain (1x), integration time of 12ms

Data = 0x00

WriteByte(Address, Command, Data)

//High Gain (16x), integration time of 101ms

Command = 0x81

//Timing Register

Data = 0x01

WriteByte(Address, Command, Data)

Command = 0x87

//Gain Control Register

Data = 0x20

WriteByte(Address, Command, Data)

//Read data registers (see Basic Operation example)

//Perform Manual Integration of 50 us

//Set up for manual integration

Command = 0x80

Data = 0x01

//Disable ADC_EN

WriteByte(Address, Command, Data)

Command = 0x81

Data = 0x10

//Set manual integration

WriteByte(Address, Command, Data)

Command = 0x80

Data = 0x03

//Enable ADC_EN and begin integration

WriteByte(Address, Command, Data)

//Integrate for 50ms

Sleep (50)

//Wait for 50ms

//Stop integrating

Command 0x80

Data = 0x01

//Disable ADC_EN and stop integration

WriteByte(Address, Command, Data)

//Read data registers (see Basic Operation example)
