Thanks.
I usually do 485 by
#use rs232(baud=115200, xmit=PIN_C6, rcv=PIN_C7
and the just use putc on the line with a max 485 chip. Is this the correct way?

Firstly as I have stated it depends on what pic you are using and what your sample rate is.
You have to set that manually with a statement such as

Just to ensure that I am understanding correctly. Is this what you suggest?
i2c_start();
i2c_write(HMC6352_I2C_WRITE_ADDRESS);
i2c_write(0x77);//write to eeprom

Thanks dyeatman.
Should it be in sequence with one i2c_start at beginning of each comand and stop at each comand or one start comand, 3 data comands and then 1 stop comand. |

{
int8 lsb;
int8 msb;
i2c_start();
