Forum Post: RE: tmp112 i2c with cc1101 spi

Hello Erkan,

There is no CS with I2C.  It only uses two wires.  If the pic has I2C then you wire those two lines directly to the TMP112 with pull up resistors on the SCL and SDA lines.  If you are looking for an SPI sensor, then the TMP121 to TMP125 is what you want.  You can use the parametric search to help in selecting a sensor to meet your requirements.
