PCM programmer. I think you are right. Your program did not work either which makes me think there is a hardware error. Have you used an external oscillator for your slave? If so what was the frequenc ...

Thank you guys, I will work on your suggestions and keep you updated.

We looked at this with the logic analyzer and can see that the Master [NXT] I2C Read stops dead after the first two bytes are sent to the slave (PIC).
1st byte: 0xA1 (Read)
2nd byte: 0x02 ("Reg ...

The pre-programmed chip has an address of A2. However, I have changed the master's program to call the 0XA0 address.

Yes I did. I have tested my circuit with a pre-programmed PIC from microchip and it works. Therefore, the problem is in the software for sure. However, I'm not using an external oscillator. I don't kn ...

I'm using a LEGO Mindstorms NXT Brick to make a sensor for a LEGO Mindstorms NXT. The baud rate of the LEGO Mindstorms I2C is 9600 bits/s. If you need more information please use the link below.

Thank you. This helped a little bit. However, I still can't communicate with my master (an external device not a PIC). I was able to communicate with another pre-programmed chip from Microchip. So the ...

Hey Guys,
I'm using a PIC18F2420. I would like a very simple slave code that returns a "1" when the master asks for data. I've been trying the code that came with the compiler but it's not ...
