How to choose digital channels to acquire

[Tamires]

Hi,

I'm using Analog Discovery 2 to perform data acquisition through digital channels, in a C++ application, based on the DigitalIn_Sync.py code, available in the SDK.

I want to choose which digital channels the data should be acquired (eg DI0, DI2, D8, D9 and D15).

The function FDwfDigitalInStatusData(HDWF hdwf, void *rgData, int countOfDataBytes) gives me the data information of all 16 AD2 digital channels.

Is there any function that I can specify the channels that I want to get the data and only they are given to me?

Hi @Tamires

The bits in each sample represent DIO 15...0 There is no option to change this but you could use masking and/or shifting in your application as needed.
