Voice recognition

Cenlasoft

Hello,
Does anyone know if there is an ic other than the hm2007 (only in india and not dip format). I want to use the prop to recognize a few commands for a robot. Foward, Backwards, right, and left.
Thank you.

Thanks for the information. In the source code (spin), It is using the TV. I have a prop professional board and I can't seem to find what pins to use for the TV. I created the circuit for the microphone already and saw where to change the pins for that. Thanks.

Looks like it was written for the Demo Board, which uses P12 as the Base Pin for TV. TV uses P12,P13,P14 and P15 is optional, (aural subcarrier).

On the PPDB, P12 would go to V0, P13 to V1, and P14 to V2.

There are no predefined I/O pins for the video. You can jumper V0, V1, V2, and optionally VA to any set of I/O pins starting at a multiple of 4. Most commonly P12-P15 are used.

Of course, Mike is correct. What I should have said is "TV on the Demo Board uses P12,P13,P14 and P15". Use these pins if you do not want to change the code.

Where the main program picks the base pin, is line 44 [ tv.start(12) ]

Thanks everyone. I set it up on ppdb and I cannot get it to work. I tried using Jef's suggestion of the robot code with leds red, yellow, and green to indicate learning. the green led flashes three times and then the red led turns on and stays on, sometimes the yellow led flashes. thanks, Curtis
