I2C issue

[pr83]

I had a couple of questions.
I am trying to implement I2C interface between a master and slave device.
1. I see there are pull up resistors connected to the SDA and SCL line of both the device(Master and Slave). Is that an issue, and what will I need to do?
2. I get some values in the slave device from its 10 bit ADC. I have been multiplying that number to an ADCfactor = (5/(2^(10))). But instead of doing this I want to take that number coming out of the 10 bit ADC and send it to the Master in 2 write commands so it could be packed into a 16 bit value. How do I take that number and convert into a bunch of 0s and 1s as a 16 bit packet. I also have some instances when I need to convert that number coming out of the ADC in the slave as just an 8 bit number and send it to the Master through just 1 write command. What will I need to for that.

What are the resistor values ? For a 5v i2c bus, the lower limit for
the pull-ups is about 1.6K. If you have two pullup resistors, use the
"product over sum" formula to find the effective resistance.
Example:
One side has 4.7K. The other side has 3.3K.

Thank you PCM Programmer. You are correct I can treat them as Rs in Parallel.
