I2C Slave with 33J12MC201

Guest · Posted: Tue Apr 15, 2008 10:03 pm

I'm trying to set up a dsPIC33J12MC201 for I2C slave use as follows:

#use i2c(slave,Fast,sda=I2C_SDA,scl=I2C_SCL,address=0x08)

But I get the following error: Bad Option: SLAVE

The datasheet clearly indicates I2C slave support for this part. What gives? I'd really rather not have to implement all of this myself.

Notice that your slave address isn't compliant with I²C specification.
To be sure to have a correct address choose it in the range from 0x10 to 0xF0.
There is a few other possibilities but in this range all values are allowed.
