RF430FRL152H: Connecting through I2C

Renan Santos Adriano

Part Number: RF430FRL152H
Other Parts Discussed in Thread: TMP112, ASC-STUDIO

Hello Team,

My Customer wants to connect the TMP112 with the RF430FRL152H through I2C.
1) Which option should they select in ASC-Studio for "Host MCU I2C Master"?
2) And they wondered how the frequency of the SCL is determed in the code? they want to communicate with 100kHz due to dimensionation of the Pull-Up-resistors.
3) Which firmware project from the RF430FRL152H should they use as the basis for this Code and why?

Thank you and very kind regards

Renan

Hi Renan,

all necessary information about the build in ROM firmware can be found in the Firmware Users Guide:

http://www.ti.com/lit/pdf/slau603

see also the Technical Reference Manual:

http://www.ti.com/lit/pdf/slau506

As start for a project that uses a digital sensor the RF430FRL152H_SensorHub_Project should be used, which can be found in the following ZIP archive:

http://ti.com/lit/zip/slac691

In the subroutine DigitalSensorInit the initial configuration of the sensor has to be made including the setting of the frequency. In the function DigitalSensorMeasurement the actual measurement has to be done and then the result is passed to the ROM firmware via the Mailbox.

Best Regards,

Helfried
