Yeah.. I have a cheap (like $15 buck or something) Casio FX-115ES PLUS on my desk which I use for quick Decimal to Hex and Binary Base N conversions.

This one. It's actually really great for the money, but I mostly work in very dim light (except for my big monitor), so I can barely read it at night:

But the problem is that the display is not backlit, so most of the time I cannot read it after 5PM! LOL ... but I did order a USB light from China a few days ago... but this Casio is 'da bomb... me thinks.

.... guess I will wait to see if the price drops a bit more by the weekend and then buy it and ship it here. It's twice as expensive here in TH even with Amazon shipping included!

I like the fact we can write Python on the computer and transfer to the Casio via USB and do data AQ as well; even though it is only MicroPython with limited capability, but still !!

EHCI(4)                                                    BSD Kernel Interfaces Manual                                                    EHCI(4)

NAME

     ehci -- USB Enhanced Host Controller driver

SYNOPSIS

     device ehci

DESCRIPTION

     The ehci driver provides support for the USB Enhanced Host Controller Interface, which is used by USB 2.0 controllers.

     EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol.  This means that they normally have one or more companion
     controllers (i.e., ohci(4) or uhci(4)) handling USB 1.x devices.  Consequently each USB connector is electrically connected to two USB con-
     trollers.  The handling of this is totally automatic, but can be noticed since USB 1.x and USB 2.0 devices plugged in to the same connector
     appear to connect to different USB busses.

SEE ALSO

     ohci(4), uhci(4), usb(4)

HISTORY

     The ehci device driver first appeared in FreeBSD 5.1.

BUGS

     The driver is not finished and is quite buggy.

     There is currently no support for isochronous transfers.
