14.1 AIN Extended Features [T-Series Datasheet]

Available AIN Extended Features

For any given AIN channel, one AIN-EF feature may be selected. AIN-EF indices:

AIN-EF Usage

To use any AIN-EF:

1. Set the EF_INDEX to select an extended feature
2. Configure the extended feature using the EF_CONFIG registers
3. Configure normal AIN configurations through the normal AIN registers
4. Read from READ_A to perform the extended feature operation
5. Read additional results from B, C, and D

For a quick example of setting up an AIN-EF in thermocouple mode, see Configuring & Reading a Thermocouple.

1. Set the AIN#_EF_INDEX to select an extended feature

Each AIN-EF index requires different configuration parameters, so the meaning of the AIN#_EF_CONFIG registers depend on which AIN#_EF_INDEX is set.

3. Configure normal AIN configurations through the normal AIN registers

Analog input range, resolution, settling, and negative channel settings are configured through the normal AIN registers.

4. Read from AIN#_EF_READ_A to perform the extended feature operation

Only reading AIN#_EF_READ_A will trigger the selected AIN-EF operation. The AIN#_EF_READ_A result is returned. Additional results are saved for later retrieval.

If the AIN-EF index uses stream-burst, reading AIN#_EF_READ_A will block for the length of time it takes to collect the necessary samples.
