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
