Unfortunately I didn't think about Windows at all when I
designed the firmware. The device just exposes a vendor specific
class. It also has a bulk in and out endpoint, and an interrupt
in endpoint, all of which are currently unused in the latest
firmware (they were previously used, and I've forgotten to
remove them from the descriptor).<br>
<br>
In the first version of the firmware I streamed back every
sample taken by the ADC to the PC, using a standard serial
class, however I ended up having problems with this (I can't
remember exactly what). The newest version of the firmware
dropped the tracing ability in favour of accumulating onboard
and sending back the final energy figures, which turned out to
be much more robust.<br>
<br>
I don't think there is any reason the serial link couldn't be
added back in. There is an example using libopencm3 here:<br>

That's great thanks James. I'm going to be out of the office next
week but look forward to picking this up on my return :)<br>

Hi James,<br>
<br>
That's really useful thanks. I have some background in USB
development so can see where you are coming from with this.<br>
<br>
Am I right in thinking that the device is a HID class device, or
is it more custom than this? (thinking about Windows driver
support here)<br>
<br>
I had assumed that it would be enumerating as a standard serial
class device and you would have a protocol running over the <br>
virtualised serial link, this being easier in terms of driver
support on host OS platforms.<br>
<br>
Was there a reason for not going down the USB serial route? I am
wondering how difficult that would be for me to put in place?<br>
<br>
Thanks!<br>

<div class="moz-cite-prefix">Hi Alex,<br>
<br>
I haven't gotten round to writing up the protocol yet, but
it is reasonably simple. Here is a fairly long and detailed
email, which will probably be copied to the wiki at some
point.<br>
<br>
<br>
The device appears as a custom USB device, and all of the
commands are sent as control transfers. There is almost a
one-to-one mapping between the methods in the <tt>pyenergy.EnergyMonitor</tt>
class and the control transfers performed to the device. The
only slight complication is there are 3 ADCs and 4
measurement points, the mapping of which ADC measures which
measurement point is done in the <tt>enableMeasurementPoint</tt>
method (with request number 7).<br>
<br>
For the exact details, see: <a moz-do-not-send="true"
href="https://github.com/jpallister/stm32f4-energy-monitor/blob/pyusb/src/python/pyenergy.py">https://github.com/jpallister/stm32f4-energy-monitor/blob/pyusb/src/python/pyenergy.py</a><br>
<br>
The actual control transfers themselves use the <tt>bRequest</tt>
parameter of the control transfer to differentiate between
types of action. The <tt>wValue</tt> and <tt>wIndex</tt>
parameters both specify data for that particular request.
There are many possible requests:<br>

they are averaged over the last 32 samples. This

I'm not sure how this would be implemented in .NET, however
if there are bindings for libusb, then it boils down to some
fairly easy control transfers. The USB device appears as ID

<br>
Here the code is performing a control transfer on endpoint
0xC1 (indicating there is data to receive, endpoint 0x41 is
used when no data needs to be returned). Request type 8, for
"is running", then the measurement point as wValue. The
final parameter indicates 4 bytes to be returned. This is
converted to a boolean. I suspect it would be similar in
.NET.<br>
<br>
The board should be fairly forgiving about the sequencing of
requests sent to it, with the exception that Bad Things will
happen if different ADCs are mapped to the same measurement
point in request 7.<br>
<br>
If anything is unclear, or I've missed out some vital bit of
information, just shout.<br>
<br>
