Communication between Excel and my bench instruments is over GPIB but for the Espruino I am using the USB cable. It appears as COM12. In addition to Excel you will need to install IO Libraries from http://www.keysight.com/find/iosuite .
The attached screenshot shows data from Espruino on row 9 (cell A9,B9,C9,D9). Row 7 has data from my instruments. The graph in the lower right corner shows output voltage of the testobject as function of load current measured by a 34401 precision meter (blue) and same measurement from Espruino. I used a simple Median filter to remove measurement noise. You can see the 16.6mV steps caused by the 12 bit resolution when a measurement range of 68V is used. It should be possible to improve the Espruino filter to smooth the line.
The test object is a buck-boost converter that is capable of handling power flow in both directions, and I am adding digital control so I can demonstrate the function of the power stage.
