Other Parts Discussed in Thread: TMP006

Hi!

I have a little problem, I would like to connect via I2C tmp006 using 16 sensors on the example that comes in the tiva, but I have problems to enable other ports I2C ...
could you help me?
Thank you

Hi,

since there can be 8 sensors on each bus, you will need one extra I2C controller. I suggest you look at the TIVA PinMux utility, since it will nicely tell you what is needed and how to enable it.

certain is that we use the I2C3 and I2C0 I2C will place every 8 sensors, but do not know whether to put 16 define

As a suggestion, you could extend the define to include a controller ID like this:

#define TMP006_I2C_ADDRESSR3 0x0342

where the 0x00 is the ID for I2C0 and 0x03 for I2C3. Then you can select the I2C controller base from the ID field.

Hello Fernandez,

The function TMP006AppErrorhandlerR could not be found by the linker. Where is it declared? If it is in the senortlib then you would need to rebuild the sensorlib driver library. If it is a new file in the project you have, then please make sure that it is included in the compile
