Hi sanjosanjo, The SPI_Transfer_Ess method accepts two parameters: data array and a control string. The SS is controlled by specifying 0,1,2,3 in the control string. See the 3.5.3 sub_spi_transfer_ess section of the User Manual for more info. We are going to add the _Ess methods into the .NET docume...

Yes, these warnings due to the newer version of the header file. Starting MATLAB 7.6(R2008a), you can use the function 'IsNull' to verify if a LIBPOINTER is pointing to a null reference. For previous product releases use a try-catch block http://www.mathworks.com/support/solutions/en/data/1-4WQ8HZ/i...

Hi sanjosanjo, Here is the code you can use loadlibrary('C:\WINDOWS\system32\sub20.dll','C:\projects\sub20\matlab\libsub.h'); hSub20=calllib('sub20', 'sub_open', libpointer); buf = 'a':'z'; [size, dummy, SerialNumber] = calllib('sub20', 'sub_get_serial_number', hSub20, buf, length(buf) ); status=cal...

Hi Russ, ...It would be nice if the examples were in C# and not just VB. vb.net and C# are very similar in terms of usage of the .NET components. All the differences fall into data types related and language syntax related. Let us know what vb.net sample you have difficulties with and we will provid...

In some rare cases, when a problem is not obvious we ask our customers to provide us with a trace log of communication between SUB-20 board and a host PC. Capturing trace log under MS Windows This can be achieved by using the SUB-20 tool GUI application, included into the standard SUB-20 software pa...

Hello Mike
There is nothing hidden in the sub20.dll. The SPI_SLAVE and all the other constants are C/C++ preprocessor definitions, located in the C:\Program Files\SUB-20\inc\libsub.h header file. You can use this file as a reference.

This VEE Sample demonstartes using of the SUB-20 SPI interface.

Agilent VEE is a graphical dataflow programming software development environment from Agilent Technologies for automated test, measurement, data analysis and reporting(Wiki). There is a good document http://cp.literature.agilent.com/litweb/pdf/E2120-90011.pdf which describes using the VEE. The "7. U...

Hi hatepod,

The SUB-20 doesn't support interrupts currently. It has an "edge detector", but you still need to call a function to read the detection result, i.e basically the same polling. The only advantage is that this functionality can be used for edge triggered interrupts detection
