This small footprint example uses the built-in ROM library. This example includes the required patches for the ROM code. It also defines a custom command example. With this example, a thermistor can be used for temperature measurements over RF. Other sensors can be used.
This example cannot have a user main function as it is built into the ROM code. Because the ROM uses the SD14, eUSCI, RF module, GPIO, watchdog, and timer modules, these modules cannot be used for custom code. Any required functionality needed is likely available as part of the ROM library functionality. However, if any desired functionality is not available, then using the NFC example project may be the only option, because it does not have these restrictions.
