iMon Helper utility updated

iMon_Helper has been updated to provide (slow) remote control support without needing Growl. In addition, I compiled it to be a Universal Binary. View the included README file for details.

Download the latest version now!

I am hoping to get this project up on SourceForge to encourage further development.

iMon Helper utility available

I just completed a new helper utility that will allow a standard LCDproc install to communicate with your iMon display. No more compiling special Mac OS X iMon drivers for LCDproc!

iMon_Helper is intended as a go-between to allow your Mac OS X installation of LCDProc to communicate with your iMon display. Because it is installed a separate binary, you will not need special Mac OS X specific compilations of LCDproc or the iMon driver to take advantage of the features of your iMon display. This will allow you to keep updated with the latest features of the iMon LCDproc driver.

Download the latest version now!

Unfortunately, I have not tested it on the newest Mac OS X or in 64 bit. Leave a comment if you have any problems.

Cox web hosting also recently ended their service, so the previous downloads I have posted are no longer available. I will try to get a version of GrowLCDproc up ASAP.

Receiving HID remote codes!

So I tried taking another look at getting remote codes from my iMon Soundgraph (0x0038) LCD. I am receiving the remote codes finally! I need to do some more work cleaning up the code and I think I can get something released!

iMon LCDproc Compiler Script Update

See the original iMon LCDproc Compiler Script post for installation details.

Many new features have been added:

Auto Discovery

The driver will now auto-discover your iMon device with no need to edit the LCD.conf file. You can still specify specific product and vendor ids if you wish.


The new driver works with newer iMon HID devices (with "HID" printed on the back), to allow Mac OS X to open the device and let you use your remote control as a mouse. Several Mac OS X drivers are available to extend the use HID devices and will now work with the remote buttons. If you had an older version of the iMon installer script that installed the LCDprocUSBShield.kext, you will need to reboot after you run the install script to gain full control of your remote.

Older iMon devices that use the iMon Pad remote, but do not use HID, such as the 0xffdc VFD, can also use the remote with the help of a few programs:

  1. GrowLCDproc 1.4.1, 1.3.11 or newer must be running and connected to lcdproc.
  2. Remote Buddy must be running with the "Script Remote" enabled in the "Hardware" area.

The imon lcdproc driver will send remote control button presses to GrowLCDproc, which in turn, sends commands to Remote Buddy via AppleScript. Remote Buddy is not a free product, but it is so professionally written with so many excellent features that it is worth the money. Remote Buddy has many options to control all of your essential Mac OS X programs. There is also a free 30 day download available.

Improved features with 0x0038 SoundGraph LCD

New features have been added that improve the stability of the SoundGraph LCD and allow users to control what the LCD will display after LCDproc shuts down.

Good Luck!

GrowLCdproc 1.4.1 Available

Growl Claw

GrowLCDproc 1.4.1 is now available for download.

GrowLCDproc 1.4.1 is compiled for 64-bit Leopard. It also includes a feature to display the current date and time when no other notifications are visible. It is largely untested and may have some minor bugs in the configuration screen. It appears to work otherwise.

See it in action.

Take a look at the documentation.

Download the latest version now.


GrowLCDproc 1.3.11 is now available for GrowLCDproc users using Pre-Leopard Operating Systems. It has all of the features of 1.4.1, but works with Mac OS X 10.4.


GrowLCDproc 1.4.1 fixes an error in GrowLCDproc 1.4.0 that would cause the display to not load on some systems.

iMon based VFD and remote on ebay

CoolerMaster Multimedia Pack

This seems like a good deal:

Cooler Master RC-260-OSB1 Multimedia Value Pack w/VFD M. Less than $15 shipped.

I just bought my next project!

Update 4-NOV-2009

This device lists as: Product ID: 0xffdc Vendor ID: 0x15c2 and works with the iMon LCDproc Compiler Script. Just change the /usr/local/etc/LCDd.conf file to include the proper USB Product id.

I was also able to get the remote working with some additional code, applescript and the very impressive Remote Buddy


iMon LCDproc Compiler Script

I uploaded the iMon LCDproc Compiler script / installer for Mac OS X. You need to have the Apple developer tools installed to use it. The script will download the latest LCDproc, compile it and install it with the iMon LCD driver. You may need to edit the LCDd.conf file to suit your particular LCD. This will likely block the mouse from working on your remote.

To use it, just:

  1. Download the latest version now.
  2. Open the iMon_LCDproc_Installer archive
  3. Double-click the "install.command" script
  4. Enter your password to allow installation
  5. Edit the /usr/local/etc/LCDd.conf file to include the product id of your iMon display

Download the latest version now.


The iMon LCDproc driver for Mac OS X now supports many more iMon displays including product IDs 0xffdc, and 0x0037.

Update 2009-12-21
