SP03 - No Luck

[JavaRN]

I've connected everything for my SP03, but I cannot communicate. I tested the connections with a multimeter and everything seems ok the parts seems to be connected in the right way. I am including a copy of the program I am using to connect to the SP03, if anyone can see any errors (logical) please tell me because I cannot find anything wrong:

(Note: This is not my work, I got it from NovaOne, just a copy and paste, may be I forgot something)

You are missing a few of my original lines:

You should have filled the speech buffer, but

The datasheet then seems to say that if you wish to speak the contents of the buffer, you send the SPKBUF command &H40

I2cAddr = &Hc4 'SP03 default address
I2cReg = 0 'Command Register
I2cData = &H40 'Speak Buffer command
GOSUB I2cByteWrite

The orignal code I posted does work, please compare your code with my original for any more mistakes.

Also to speek predefined phrases:

Using the free configuration program you can load upto 30 predefined phrases into memory. This should play a phrase back:

I2cAddr = &Hc4 'SP03 default address
I2cReg = 0 'Command Register
I2cData = &H01 'Speak 1st predefined phrase
GOSUB I2cByteWrite

I'll try to help as much as i can...

I also noticed you have added the Start_Speech and say_hello routines which are just the FillSpeechBuffer routine split in two?


Just add this after GOSUB FillSpeechBuffer in the Main loop:


I2cAddr = &Hc4 'SP03 default address
I2cReg = 0 'Command Register
I2cData = &H40 'Speak Buffer command
GOSUB I2cByteWrite

Or you could delete the contents of your Start_Speech routine and insert the above code. Then GOSUB Start_Speech after GOSUB FillSpeechBuffer
