Connecting the Babblebot to the Handy Board
The Babblebot is a carrier board for the SpeakJet voice synth chip. Here is the 1-page manual for the Babblebot board.
The SpeakJet web site is a horrible Flashified mess. Just get the PDF user manual.WHEN BUILDING THE BOARD: MAKE SURE TO USE AN 18-PIN SOCKET FOR THE SPEAKJET CHIP. DO NOT SOLDER THE SPEAKJET CHIP DOWN TO THE BOARD!!!!!!!!!!
Please also note that the electrolytic capacitors (small cylinders) are polarized. Find the lead labeled – (minus). The other lead is + and goes in the hole marked + on the board.
To connect to the Handy Board on Digital "Input" 9 (which can function as a 9600 baud serial output). Get the driver from here. Use the non-inverted TTL version.
Here is a diagram of the HB's digital input bank. Connect the Babblebot to x, +, and -:
[ ][ ][ ][ ][ ][ ][x][ ][ ] [ ][ ][ ][ ][ ][ ][+][ ][ ] [ ][ ][ ][ ][ ][ ][-][ ][ ] 15 14 13 12 11 10 9 8 7
- x is the signal output; connect to Babblebot x pin.
- + is the +5v supply; connect to Babblebot V+.
- - is ground; connect to Babblebot Gnd.
Do this by building a pin header connector like the HB's standard sensor and motor connectors.
Find a cheapo computer speaker for the Babblebot from the computer recycling center in Olney.
Software:
- Schuyler uploaded some sample IC driver code onto a InventionDB entry. The sertest.c file included with the driver isn't relevant to the BabbleBot directly.
- We have a pre-release version of the Win32 desktop software for the SpeakJet.
