CMUcam3: Open Source Programmable Embedded Color Vision Platform

lexo — Fri, 09 Jul 2010 23:59:38 +0000

The goal of the CMUcam project is to provide simple vision capabilities to small embedded systems in the form of an intelligent sensor. The CMUcam3 extends upon this idea by providing a flexible and easy to use open source development environment that complements a low cost hardware platform. The CMUcam3 is an ARM7TDMI based fully programmable embedded computer vision sensor. The main processor is the NXP LPC2106 connected to an Omnivision CMOS camera sensor module. Custom C code can be developed for the CMUcam3 using a port of the GNU toolchain along with a set of open source libraries and example programs. Executables can be flashed onto the board using the serial port with no external downloading hardware required.

OpenPICUS

lexo — Tue, 11 May 2010 22:52:26 +0000

OpenPICUS is PIC 24F series (16 bit) based new open hardware platform with embedded wireless module (Bluetooth and Wi-Fi). The project will let developers (hardware and software) create their advanced wireless sensor applications even without any hardware experience. At this time, the project is under development. If you have great idea and want to contribute to the project, you will have a chance to get OpenPICUS evaluation board for FREE.

Here is main characteristics of OpenPICUS:
HARDWARE

* CPU Microchip PIC 24F 16 bit 44 pins QFN 64K Flash 8K Ram)
* Wireless (Bluetooth / Wi-Fi)
* Power 5V or 3,3V
* Main connections: UART, Digital Inputs, Digital Outputs, Analog Inputs, PWMs, SPI display, I2C
* Connector: 26 Ways IDC header (male) suitable for TH mounting or flat cable
* SMT: 26 Pins for direct soldering PICUS to a PCB

Software

* PICUS gives a possibility to upload software by a serial port (you do not need a Microchip programmer).
* Bluetooth offers SPP, OBEX, Headset profiles.
* Wi-Fi gives an access to the integrated webserver, TCP socket, embedded FTP and email clients.

Using Asterisk PBX to Control your Arduino

lexo — Thu, 10 Dec 2009 20:54:26 +0000

I was searching something about integration of Arduino with Asterisk PBX and I found this interesting article:

Using Asterisk to Control your Arduino

This article is how to control Arduino over Ethernet using Asterisk PBX, making a call and controlling over it comm channel.

So then, you can make a IVR and control your Arduino calling it wherever you are.
