Digital Discovery - Script Question 2

[engrpetero]

I have been using the Waveforms Protocol panel to successfully send SPI messages using the Digital DIscovery device.  For now, I Execute two long sets of bytes (an example of the second set of bytes is shown in the pic below).

In playing with the scripting, I'm trying to do the same thing but by sending many sets of three-byte-blocks instead of just that one long DQ0 line above.  The simple script is shown below.  FWIW, the content in DQ0 above is the second set of Write's in the script after the wait statement.  Anyway, I don't get the same result when I execute/Run this simple script.  Any assistance with the solution?

 

clear() // clear the output window

print ("Starting script...");

print("Lowering chip select.");
Protocol.SPI.Start();

print("Peforming the init sequence from the NewHaven user manual.");
Protocol.SPI.Write (8, 0xF8, 0x50, 0x40);     // Function set (extended command set)

Hi @engrpetero

Function expects an array of words.
Protocol.SPI.Write (8, [0xF8, 0x50, 0x40]);

Well, heck, I missed that.  Works now.  Thanks @attila. :-)
