intuitional way. The user only needs to connect the USB Programmer between the PC and the device, fill in/select the proper

value of each parameter on the RFPDK, and click the “Burn” button to program the configurations into the device. The

configurations of the device will then remain unchanged until the next programming. No external MCU control is required in the

application program.

The RFPDK also allows the user to save the active configuration into a list by clicking on the “List” button, so that the saved

configuration can be directly reloaded from the list in the future. Furthermore, it supports exporting the configuration into a

hexadecimal file by clicking on the “Export” button. This file can be used to burn the same configuration into a large amount of

devices during the mass production. See the figure below for the accessing of the EEPROM.

5.4 All Configurable Options

Beside the demodulation, frequency and symbol rate, more options can be used to customize the device. The following is a table

of all the configurable options. On the RFPDK, the Basic Mode only contains a few options allowing the user to perform easy and

fast configurations. The Advanced Mode shows all the options that allow the user to customize the device in a deeper level. The

options in “Basic Mode” are a subset of that in the “Advanced Mode”.
