HouseBot

I've attached the dll and the source code for the $25 DATAQ 194rs data acquisition module ( http://www.dataq.com/194.htm ). The module contains four analog/digital conversion channels and three digital inputs. The plug-in reads all the channels, but I did not bother displaying data from digital chan...

Hi, Apparently, HouseBot does not decode the low battery status with X10 DS10a door open/close sensors. Here's a W800RF32 interface trace for the normal case: "1/15/2009","7:16:27 am","W800RF32","Debug","W800 received raw data [3f 30 04 fb]." "1...

Scott, The suggestion to disable the disk on-board write cache is a good one, but folks probably should be aware of severe performance consequences. As I posted elsewhere: "On my laptop, with WCE (write cache enabled) I get 20MB/s throughput for 64K OS-cache-bypass writes; without WCE I get onl...

Mark, Interesting ... The device is "rated" at -20C which is -4F so it should work around 32F, but I guess it does not. I wonder how you connect the device to your computer. Is your PC located outdoors ;) ? I thought about measuring the outside temperature with wireless temperature sensors...

Here's the dll with read-only Temperature -- posted to a wrong thread first time

I've attached a dll with the read-only Temperature property (ioInputOnly). I believe the device has to be recreated for ioInputOnly (should it not be rather called ioOutputOnly ?) to take effect.

I've attached the modified piece of code and the DLL.

It works with < 10 COMxx ports.

OK, I think the problem is caused by naming: http://support.microsoft.com/kb/q115831 If you want to specify a COM port name higher than COM9, the "correct" syntax is: "\\\\.\\COM20" I'll modify the code and see if it still works with lower port numbers. I cannot force my laptop t...

Hi, Error 2, as any other possible error, is just a MS standard system error. '2' means that the the 'file' or rather the com port does not exist ( http://msdn.microsoft.com/en-us/library/ms681382(VS.85).aspx ). Did you change the default 'COM4' to to 'COM 20' ? You can do that with the device runni...

Hi, I've created a simple plug-in that can read this ( http://www.funponsel.com/blog/archives/2007/10/01/temper-usb-thermometer-for-laboratorians/) inexpensive (~ $10 on e-bay) USB thermometer. The plug-in can be compiled using VS 2008 Express. I had to make minor changes to the SDK Device.cpp (cast...
