Test setup for interfacing the SP03 to an OOPic.

Introduction

In this example, an OOPic module uses a Devantech SP03 Speech Module to say pre-programmed phrases.

Circuit Schematic

In the following schematic, the SP03 is connected to the OOPic's I2C bus through its empty EEPROM socket, which also provides power and ground.

Wiring diagram between the OOPic and the SP03.

A close-up of the ends of the custom interface cable built for this example is shown below. The wires on the 2-pin male connector are SDA (denoted by black tape) and SCL. The red wire is ground. The other wire is +5V. Each wire has a female connector placed in the appropriate slot in the black housing. The black housing connects to the SP03. The male ends fit into the EEPROM socket.

Source Code

This code uses BASIC syntax. It runs with version 5.0.1 of the OOpic compiler and version A.1.7 of the OOPic chip.

The OOPic oI2C object provides an interface for the SP03. The sayphrase subroutine initializes the I2C communication and sends a command across the bus to make the SP03 speak one of its 30 stored phrases. The routine polls the SP03 module to find out when it has completed saying the phrase. Stored phrases are convenient for common messages. For a robot, some examples might be "ouch", "hello master", or "my batteries are low".
