Has anybody managed to get the SP03 working with an Arduino.
Data sheet here for SP03
http://www.robot-electronics.co.uk/htm/Sp03doc.shtml
You can store 30 phrases using a custom app and then call these phrases using the MCU. Alternatively you can feed it text to it sbuffer and then request it speak this text.
Example code here for the basic Atom

I have wired up the I2C interface to the Arduino as follows : +5v, both gnds, and the SDA to arduino analogue pin 4 and the SCL to Arduino Analogue pin 5. When I power up the the synth it speaks the default text that is stored in the first storage space. This is what its suppose to do simply by getting power
I am pretty new to Arduino and I2C maybe too ambitious
My code is:
#include <Wire.h>
void setup()
{
Wire.begin (); // join i2c bus
}
void loop()
{
Wire.beginTransmission(0XC4); //predefinedI2C address of SP03
Wire.send ("0X01");
Wire.endTransmission();
}
Obviously nothing happens when I run this although the code does actually compile.
I am missing selecting the Command Register
I have read a few articles on I2C but not enlightened yet
This is from the data sheet
To say "Hello" send the following sequence over the I2C bus:
Start Bit I2C Start Sequence
0xC4 SP03 I2C Address
0x00 SP03 Command Register
0x00 SP03 NOP Command
0x00 Volume (Max.)
0x05 Speech Speed
0x03 Speech Pitch
'H' (0x48) Text
'e' (0x65) Text
'l' (0x6C) Text
'l' (0x6C) Text
'o' (0x6F) Text
0x00 NULL
Stop Bit I2C Stop Sequence
I'd appreciate any help
