Units of parameters obtained using "readHistogramData()" function? #5

Hi @marlon360

Thanks for this wonderful work. I would be grateful if could please clarify the units of various parameters which we can obtain by using "readHistogramData()" function. The parameters for which I want to know units are in the image below (the data obtained using your library):

esp

The image below shows the units and values of the parameters obtained when SPI-USB converter and their software is used:

spi_usb

The values of corresponding variables are different by orders of magnitude, so I suspect that units are different when using their software and when using your library.

Waiting for your reply. Regards.
