We are working on a data acquisition application via SPI, and we already achieved reading from our sensors with NI-USB8452 from a C++ program. However, we have to manually ("polling") issue writing+reading commands to read each measurement, which imposes some delay. 

Is there any way to tell the USB board to perform some SPI script automatically at a fixed rate? In that case, how are the reading data retrieved from the C++ program?

Best,
