Where is the software for the TIDM-RF430-TEMPSENSE EVM?

There is no software download for the TIDM-RF430-TEMPSENSE EVM. This EVM runs from the ROM code that is part of the RF430FRL152H. The EVM does not have any FRAM programmed at production.

The RF430FRL152H ROM RF Stack plus Sensor Stack enable temperature measurements. The RF stack is used to receive configuration commands for the SD14 ADC through NFC/RFID communication. The configuration commands are written to the device virtual registers starting at the Block 0x00 for RFID commands, which corresponds to Address 0xF868 of FRAM. The virtual registers are used by the Sensor Stack to manage the ADC sampling process and read the raw ADC result from the thermistor.

The conversion from the ADC result to a temperature measurement is not done on the RF430FRL152H device. Instead, the raw ADC result is stored in FRAM and transmitted over RF. The application that receives the ADC result must convert the data to temperature. Section 4.1 describes the calculations for the conversion.


Details about device memory addressing are described in Section 4.4 of the RF430FRL15xH firmware user's guide and details about available registers and virtual register address mapping are described throughout Section 7 of the firmware user's guide.
