After applying V
to access the CONTROL register followed by the data value 03h to power up the device. At this point, both ADC
channels will begin a conversion at the default integration time of 400 ms. After 400 ms, the conversion results
will be available in the DATA0 and DATA1 registers. Use the following pseudo code to read the data registers:
Address = 0x39
//Address the Ch0 lower data register and configure for Read Word
Command = 0xAC
//Reads two bytes from sequential registers 0x0C and 0x0D
//Results are returned in DataLow and DataHigh variables
ReadWord (Address, Command, DataLow, DataHigh)
Channel0 = 256 * DataHigh + DataLow
//Address the Ch1 lower data register and configure for Read Word
Command = 0xAE
//Reads two bytes from sequential registers 0x0E and 0x0F
//Results are returned in DataLow and DataHigh variables
ReadWord (Address, Command, DataLow, DataHigh)
Channel1 = 256 * DataHigh + DataLow
Address = 0x39
Command = 0x8C
ReadByte (Address, Command, DataLow)
Command = 0x8D
ReadByte (Address, Command, DataHigh)
Channel0 = 256 * DataHigh + DataLow
Command = 0x8E
ReadByte (Address, Command, DataLow)
Command = 0x8F
ReadByte (Address, Command, DataHigh)
Channel1 = 256 * DataHigh + DataLow
