Type: SystemBoolean
If set to this method automatically calls Start if you do not explicitly call it. You cannot set this parameter to if you have installed events on the task.
data
Type: SystemUInt32 A 2D array of 32-bit unsigned integer samples to write to the task. Each element in the first dimension of the array corresponds to a channel in the task. Each element in the second dimension of the array corresponds to a sample to write to each channel. The order of the channels in the array correspond to the order in which you add the channels to the task. The order of the lines in the array corresponds to the order in which you add the lines to the channel.
Use this method for devices with up to 32 lines per port. If the task uses on-demand timing, this method returns only after the device generates all samples. If the task uses any timing type other than on-demand, this method returns immediately and does not wait for the device to generate all samples. Your application must call the WaitUntilDone method to block until the device has generated all samples.
NI-DAQmx read and write methods time out after the amount of time specified by the Timeout property on the task you are reading from or writing to.
This method returns immediately if the output buffer has sufficient space for the samples. Otherwise, the call is blocked until the application generates enough samples to fit the new data into the output buffer.
