Project "code name" Part 031

COMPACT
June 27th

Here is some Substance to the Matter

Here is a block diagram of the prototype.

What we have a block respresenting the Animated toy on the top right showing its faculties,

below it a block representing the Graphic LCD Screen

and below that Intelligent Control and Sensor modules

 

The Animated toy is been reverse engineered such that its faculties can be driven independently from its own embedded controller.

These tap points are connected to a relay board that is controlled with digital output pins from the CC3000.

 

The Animated toy also has an audio amplifier.

The audio input signal for this is derived from the CC3000 generating an analog audio signal through a SPI DAC5311IDCKT.DAC5311IDCKT. and driver buffer.

An 8-bit signal sampled at 8kHz is used.

Since the CC3000 does not have enough capacity to hold a the required data samples to generate such a signal an external SPI FRAM buffer is used.

In addition to just the audio the toy has a mouth that simulates the actions of speech it too uses the external FRAM buffer.

 

The LCD is used for displaying messages and graphics.

It is driven by the CC3000's SPI interface.

 

In addition to just driving the toy, provision has been made to accomodate Self contained Home Automation modules such as sensors and drives via its Serial Interface which is switched using a dual channel 4:1 multiplexer demultiplexer.

 

For clarity the output pins for generating the additional handshake signals such as Chip selects and device selections is not shown.

  • Good clean simple approach.

    You can always expand the channels as you need them and then implement the new devices via auxiliary controllers as needed.

     

    I like the way you kept the animation simple.  You just run two canned scripts down to the toy so it looks like the animal is doing the talking while the rest of the system does its own thing.  Simple but effective.  I suspect you could also add additional scripts to have different performances based upon which sensors detect problems.

     

    I like it,
