SP03 and I2C

[JavaRN]

I am trying to connect an SP03 speech module to Robonova through I2C. I soldered a resistor from the SDA and SCL connections to the +5V using a 4.9 K resistor as shown below:



The problem is that if I don't connect the SDA and SCL connections to the Robonova the SP03 will light up and also sounds a message and as soon as I connect the SDA and SCL lines to the robot's SDA and SCL, the SPO3 speech module lights up but the robot doesn't perform the initial routine (standing up and wait for the messages), also I cannot upload programs to it.

When I remove the SCL and SDA connections everything returns to normal. Any help please would be greatly appreciated.

These are the exact symptoms I got when I tried to connect to the EEPROM I2C port.

I'm currently using spare ports 15 (for SDA) and 16 (for SCL), Ive taken some photos but they are not very clear. I really need to draw a diagram.....

I'll upload the photos in a minute, with links in "Need for sound"

I've tested my previously posted SP03 I2C code with the routines I wrote for the Compass and you will be pleased to hear it works fine. Please remember if you try to integrate it into a standard robobasic template program to only turn on the motors ports you need for servos DO NOT the ones you are using for I2C. as some move commands my interfere.
