1 Hardware Platform
The CMT2390F64 evaluation board is consist of CMT2390F64-EB and LCD Shield.
CMT2390F64-EB is used as the evaluation board，and CMT2390F64 is the development board for chip
controller. The evaluation board is with functionality and performance evaluation by default and it can be used
as the development board for getting to know CMT2390F64.
It provides two average frquency band：434MHz and 868MHz，with +20dBm Tx power in Direct Tie
matching mode;
CMT2390F64-EB can also provide two types of standard single antenna (default) and antenna diversity
(one PCB with different BOM, double Layout compatibility)
LCD Shiled is plugged into the CMT2390F64-EB. It is used as the man – machine interaction interface
for it provides LCD screen and buttons.

4 RF DC-DC Select
The RF part of the CMT2390F64 is embedded with DC-DC module. The
DC-DC mode can either be enabled or disabled. It should be noted that
this jumper is a hardware selection and should be used together with the
control software. If the DC-DC module needs to be enabled, the software
also needs to configure the corresponding register BUCK_SEL to 1
(located in Page1, address 0x01, Bit4). Note: The DC-DC only applies to
the RF part, while not to power supply of controller part.

2 Introduction for Parameter Setting
A firmware will be pre-burned around the chip before delivery for multiple functional test and evaluation (it
needs to be used together with LCD shield display) for CMT2390F64-EB or CMT2390F64-QFN48-EB. This
firmware will be updated from time to time as functional changes, it can be downloaded from the official
website of HOPE and it will be updated through J-Flash software from J-link debugger (the updated firmware
is described in detail in Chapter 4 of this article). In this chapter, parameter setting menu of the factory
firmware will be introduced in detail.
