Here is a web site (http://www.1wireprojects.net) that uses the CGU4x1 USB devices to control home automation using 1-wire devices. The USB interfaces can communicate with 1-wire devices and forms the basis for home automation through some custom-made 1-wire interface modules. Welcome to my 1-Wire Project web site. I created this site to discuss and help [...]
The On-line Development Notebook (ODN) at USBmicro has been updated to include information on the U451 USB relay board, as well as the new commands for interfacing to 2-wire (I2C) devices. Visit USBmicro, or download the entire ODN in PDF format.
On the Liberty BASIC Community Forum was a posting asking: Has anyone used LB to interface to USBmicro I/O modules see http://usbmicro.com/ RobotBasic & VB provide this functionality The moderator “Rod” replied: If I take the short VB example listed on the web page it would convert like this. ‘open the .dll Open “USBm.dll” for [...]
New capabilities are being added to the U401/U421 firmware. The first new function that I am testing here is a “Quiz Show” function. Also called “Fastest Finger First”, as it shows which line, of all sixteen of the lines on the device, has been pressed first. This capability is used in game/quiz shows and contests. [...]
A customer was kind enough to share an example project for the U401/U421 centered around the 1-wire temperature device. The project was written in Delphi and is available for download (source and executable) here: http://www.circuitgizmos.com/files/u401delphi.zip You can get the DS1822 from CircuitGizmos along with the U401 USB Interface and the U421 USB interface
Guest blog by Samuel Mishal Hi All, One of the very exciting new facilities in RobotBASIC V4.0.0 is the support for USBmicro’s U4x1 family of USB devices that provide the ability to do digital I/O with a PC and lots more! See this guide: http://www.robotbasic.org/resources/RobotBASIC_USBmicro_U4x1.pdf
Guest Blog by Harry What do you think about when you hear the words “home automation”? I’m guessing you probably think about lighting control. Perhaps you think about temperature control. Or perhaps you think about your every need being automatically tended so all you have to do is stare at the T.V., munch on some [...]
I created a tool that runs on the command line or “DOS box” that lets you use a U401 or U421 (output) in a batch file or other type of PC script. This is output only. You can set or reset the lines on the U401 or U421 using this executable file. The program is [...]
Part 1 Part 2 Part 3 Part 4 The Mail Light hardware could easily be modified to turn on some rotary warning lights, such as these lights from Woot.com. The example pictures below show the modification of a set of these lights to be driven by a U401 which works just as well as the [...]
Post on a (sometimes offline) blog at: http://robotics.reefat.com/2008/08/22/analog-to-digital-converter-demo-sensor-interfacing/ using the U401 and an ADC0804 for analog conversion. I’ll repost the pics and code here. Oddly, the video was removed because “Fox” considers it to be a copyright infringement. Um… ?? Someone needs to explain this to me… (Author doesn’t know why, either.)
