So it is time to wrap up the project ahead of the deadline. This week will be a mixture of finishing off board layouts, summaries, and anything else that comes up. Sure to be interesting while I'm on holiday! (Just a little short notice, was only booked yesterday)

In the meantime, here is a demo video. Or would be anyway. Thanks to the previously blogged about tool chain issues (I've had great luck, only broke 3 of them ), there isn't much of a demo. Wouldn't want to disappoint however so to keep you entertained is a short presentation on the work done. This includes a very short introduction to the components and a walk through of the code. Please, ask questions should you have them. All the software parts (code and schematics) are available in the repos. If anyone wants to try to get it working, fix it, improve it, make it into a paper plane (Please keep it green. Save the paper for your next project proposal or similar!), please do. Fork away and let us know how you get on. A text based summary will come during the week.

Design Summary

This system is designed to make watching your favourite film, TV or game easier by reducing the number of things you have to do to get the environment just right. For many, the habit is to turn off the lights, close the blinds and watch the film in the dark. Lets face it, if you are going to put on a film you are looking to be lazy, so why not automate what you can?

The challenge is to do this using the Texas Instruments CC3000 WiFi evaluation kit. This project makes a few assumptions, if you are the kind of person to have a home automation system, you most likely have a smart phone, a tablet, a laptop or other wireless device (If anyone has data on how this applies to those using home automation due to a health issue, please share!) This makes the design a little easier, use the wireless device as the remote control. Something of a Bring Your Own Device approach to the problem. Why create a whole new device when you can use standard hardware and simply drop in an app? The use of WiFi (Implemented as a client rather than an access point), would also allow the user to control the system from outside the network through the internet. Stuck late at work or in traffic? Close the blinds and turn on the lights on the go through mobile internet. With this design, the system is broken down into a device per room with one base station acting as a controller. The diagram below shows how it is configured.

This system is made up of several main components, the WiFi network, the ZigBee network and the drivers. The Wifi portion connects the main user interface to the system. This means any Wireless enabled computer is able to send the relevant instructions to the system to say what mode the relevant room needs to be in. Once these instructions are with the base station, one of two things can happen. The first is that the instructions are followed. This is because the base device controls a room just like any of the end devices. If the instruction is not for the base station it is forwarded onto the right end device using the second main component, the ZigBee network.

The ZigBee protocol was chosen for a few reasons, one being previous experience with XBee modules, second being the availability of processors which natively support the protocol and lastly, the protocol is designed for this. ZigBee has several published profiles for applications and several draft profiles. Out of these profiles, there are two which fit this use, the published Home Automation profile and the draft Building Automation profile. When you look into the specifications for these, the Home Automation profile covers exactly what is being done here as it provides lighting and closure controls (Window coverings, shades etc). Couldn’t get more suitable if you tried! To make it even better, the available software stacks for TI ZigBee products are compliant, as tested by a ZigBee Alliance test house. Z-Stack samples also support the Home Automation profile. It is like a match made in heaven!

With the instruction at the right end device, you need to have an output, to do this we need two components, a lighting driver and a motion controller. With the move towards green technology, there are very few options for lights, the biggest one being LEDs. As it happens, TI provide some lovely LED drivers, including one controllable by a PWM signal. The result is a dimmable light that can be controlled by a tiny processor. Sticking with the PWM theme, this kind of signal can also be used to drive the motor of choice. With the available range of motor drivers, there are multiple options for motors, be it a DC motor, a stepper motor or a servo. For this system, a stepper motor was chosen, allowing suitable levels of precision and the use of a step counter rather than a timer. With this in mind, the solutions chosen were the DRV8805 for the motion control and the TPS61042 for lighting control.

The user interface is not just limited to the computer application however. The base station, and eventually each end device, is designed to accommodate a control panel. This means a LCD to display a menu and buttons to switch through the menu. Other options for the interface included using a capacitive touch sensor in place of buttons, much like the iPod and many touch screen devices.

The Nice Asgard Project - Part 1

Many people enjoy a good film, be it at the cinema or in the comfort of their own home. We all have our habits when it comes to watching films through our Home Cinema System (Be it big TV and surround sound or just a laptop), for some it is to turn the lights off, close the blinds (Or whatever you have), get yourself a drink and enjoy the film....

The Nice Asgard Project Part 3 - PCB Adventures

While I wait for some input on the motor control problem, its time to start piecing together the PCB for a prototype. This means breaking out EAGLE.

The first challenge for this is to find the right package....

The Nice Asgard Project Part 4 - Displays

While working on the PCB, I realised one thing. I haven't found a display yet! (Pretty useful!) There is a challenge here, the MSP430FR5739 being used does not have a built in LCD module, so any solution will have to be in software or using a different interface. The best option for me....

The Nice Asgard Project Part 5 - Displays (Again)

So it seems a bad week has gradually got worse. Out of the blue, it seems the toolchain used by CCS has disappeared (but hasn't) meaning that nothing can be compiled. While I can still write the code, there is currently no way of testing it. Rather infuriating at this point, but we shall try again another day. ....

The Nice Asgard Project Part 6 - Alternatives and How to Give Couriers De Ja Vu

The whole CCS not finding things has been narrowed down to the machine as a whole. It either needs a holiday or a kick/complete reinstall. Not a fun task either way, so in the meantime there will be a quick switch to mspgcc. ...

Project Final Summary View the full document

The theory of operation is very simple. Remote commands come through as UDP datagrams to the CC3000 via Wi-Fi and them MSP430FR5739 parses these datagrams and processes accordingly. It could not be any simpler. This because all aspects such as TCP/IP networking and Wi-Fi are handled transparently by the CC3000.

The firmware for the MSP430FR5793 contains a function that reacts to incoming datagrams and then extracts the parameters from the received payload.

Where applicable the project firmware will respond with appropriate responses such as sensor readings and command acknowledgements.

A complete solution incorporates CC3000 devices and partnering remote systems such as Twitter, PCs and portable Internet devices. The focus of this project thus far has been the development of the CC3000 based device to Ultimately Road Test it. I have plans to complete partnering support software soon to demonstrate a total end to end solution.

The toy is controlled by activating the assigned relay using an MSP430FR5793 Output Pin. The select relay switch closes which asserts the control signal on the toy causing the selected feature to be activated.

The functions under relay control are;

     Power On
     Neck Up/Down
     Mouth Open/Close
     Suspension Activate/Deactivate
     Headlights Light/Unlight
     Audio Enable/Disable

Audio is produced using a DAC (DAC5311) from a 8kHz 8-bit .WAV audio file
This is used to produce an audio level signal with in turn is amplified by the toy's own amplifier and output through it speaker
The .WAV file is downloaded via the CC3000 and stored in the FRAM buffer.

The articulation of the toy mouth is performed similarly where the corresponding .LSP file is downloaded and stored in the FRAM buffer.

Playback works by reading both the current .WAV and .LSP samples to be played and then outputting to the DAC and mouth control relay at

the desired 8kHz sample rate.

The Motor, Lighting, Digital Camera Modules and Thermopile Sensor Interfaces all use the MSP430FR5739 Serial Interface via the serial

mux/demux. The desired serial channel is selected using two digital output pins that control the mux/demux address select pins.
The MSP430FR5739 then communicates with the selected module's protocols. For the Lighting control it uses the protocol for the Multi-

DC/DC Colour LED demonstration, for the Motor control it uses the protocol for the DRV8312-C2-KIT demonstration for the Digital camera is

uses the protocol as specified by its reference manual and similarly for the Thermopile Sensor. View the full document

... "So I think it is about time to compile what I have done so far and call it a day. Here is a bit of a video of my system as it is, as you can see there is still work to be done. My project so far is still definitely in the proof of concept stage but I think it does that nicely. I have a system which is easy to expand upon and no doubt I will continue to play with in the future, I think the idea has promise.

Once thing missing is the web integration, I need to work out a way to give my Bread & Butter project an online presence to make it really useful. I may try and integrate it into my website, I'm sure people will want to know what I have in the fridge..

I will make a final post tonight when I am not at work, this will have all circuit diagrams/eagle files, the code I have written (there is actually quite a lot) and what ever else I have to include to finish off the competition. I will probably continue work on this project (slowly) for the next few months, it will all be available somewhere on the Internet. Most likely here and on my website www.HowNotToEngineer.com

Well it has been fun, I have learned a lot and got to play with some really cool toys. I would highly recommend going out and trying some of the TI equipment and tools."...
