RF430FRL152H ADC Output Register

Luciano Mogorovic

Hello,

I am using an app from the Google Play store to read a voltage over NFC from using my RF430 board. The application works great, but it shows the data on all the registers on the board. I need to know which register is connected to the ADV on the board where the voltage is coming in. I hope someone can help, thank you!!

    What you are seeing with the NFC app is all of the FRAM memory (about 2kB of it). The FRAM memory has about 64 bytes of virtual registers at the beginning that control the ROM code. The rest of the memory is mostly for the data logging. The very end of the FRAM is for the interrupt vector table.

    The ADC output registers (the logs) start at block 9. However to get any data in them you first need to configure and initiate a ADC sampling.

    At the very least this means that you need to write to block 0 which sensors to use (thermistor, ADC0 - third byte) and to start the ADC measurement by setting the start bit in block 0.

    This will get you a basic measurement. However there is a lot more configuration options like, the number of measurements, accuracy and time, and other settings. Please look at the Firmware User's Guide for all the details on the register definitions.
