using SUB-20 SPI read-write.vi

[acc-gyro]

XDIMAX has provided a LabVIEW VI (SUB-20 SPI read-write.vi) for SPI communication and I am working on using it with the SUB-20 together with an IC (acc/gyro, LSM330DL) using SPI. Eventually, I want to use the IC to develop some algorithm using LabVIEW. There are certain issues that I need help to achieve my goal. I am breaking my goal down to some smaller tasks:
1. Configure SUB-20 to give command and to read data from the 3 axis accelerometer
2. Configure SUB-20 to give command and to read data from the 3 axis gyroscope
3. Configure SUB-20 to give command and to read data from the 3 axis accelerometer and 3 axis gyroscope
4. Stream all above 6 axis data set to LabVIEW for data processing/algorithm development

The list of the 8-bit registers embedded in the device for the gyro and the acc. (they have a different CS) and the respective address:

OUT_X_L_A 0x28
OUT_X_H_A 0x29
OUT_Y_L_A 0x2A
OUT_Y_H_A 0x2B
OUT_Z_L_A 0x2C
OUT_Z_H_A 0x2D

I am having difficulties using the VI. Would you how to use the vi or to modify it to achieve my objectives?

Hi acc-gyro,

Before developing your vi in LabView I would suggest to use our GUI application - subtool, to communicate with your LSM330DL device, i.e
- Configure SPI (or I2C), SS polarity, clock edge, clock rate etc. See the datasheet for the LSM330DL
- Read registers from the device, check if reading is reliable. Then go ahead and develop your vi.
By the way, have you seen our new labview driver here

Try to achive your goal by the GUI tool, first. This will allow you to eliminate hardware related issues, like connections, grounds, pull-ups, signal levels etc.
