Please note that the configuration for the Normal scheme is not provided by the RFPDK by default. If the user want to evaluate the Normal mode, the user can follow the below steps to configure the Normal scheme, as shown in figure below
Rev 1.0 | Page 14 / 34 www.cmostek.com
AN113
Figure 17. Configuring the Normal Scheme Based on LED On/Off Scheme
1. Start from CMT2150A – Basic Mode – LED On/Off Configuration
2. Change the Button Mode from Toggle to Normal, please note that by changing this, the Study Button is changed to
Pin12(K0) by default.
3. Change the Number of Button(s) from 5 to 4
4. Burn the configuration to the CMT2150A-EM
5. Burn the CMT2250A – Basic Mode – LED On/Off Configuration to the CMT2250A-EM
After the programming is done, the CMT2150A-EM and CMT2250A-EM can be used in normal scheme with the following items to be noticed.
1. Since the push button, which should be connected to Pin12(K0), is not designed on the CMT2150A-EM V1.0, with the configuration steps introduced above, the LED1 on the CMT2250A-EM cannot be controlled. Only K1, K2 and K3 are
of the push buttons.
2. Proper configuration of the Data Pin Reset Code for the CMT2250A-EM is required if the user wants to turn off all the
LEDs at the same time. For example, if the Data Pin Reset Code is set to D0:D3 = 0100, K1 on the CMT2150A-EM becomes the Off button to turn off all the LEDs on the CMT2250A-EM.

The CMT2251A-EM is the Rx PWM control module with a CMT2251A device, a PWM controlled LED, battery case and a couple of necessary external components. The EM-Connector on the back side of the module allows the connection to the
USB Programmer. The main components are listed below:
Figure 24. Top View of CMT2251A-EM
1. EM-Connector – The EM-Connector is a 10-pin, 2.54 mm male connector used to connect to the USB Programmer.
2. Power Mode Switch –The power mode Switch (S1) is used to select the power supply source of the module. The module can be supplied by the battery (S1 switched to the VBAT side) or the EM-Connector (S1 switched to the VEXT side). It is recommended to put the switch to the VEXT side when programming the CMT2251A-EM with the USB
Programmer.
3. LED – A red LED is available on the PCB connecting the PWM pin of the CMT2251A. An NPN transistor is used to turn on the LED when there is PWM signal coming out from the CMT2251A to adjust the brightness of the LED.
The definition of the EM-connector on the CMT2251A-EM is given below:

two tabs at the top of the panel to choose the product family: either devices operating in the 2.4 GHz frequency band or the sub-1 GHz frequency band. Under each tab, all the products belong to the family are listed in the middle of the panel. The products can be filtered by the buttons of All, Transmitters, Receivers and Transceivers. The main features of the products, including Device, Function, Band, Package, Modem and Symbol Rate, are shown to assist the device selection.
If an evaluation module is connected to the PC through the USB Programmer, the device part number, USB Programmer hardware version and firmware revision will appear in the “List of connected device”.
The rest part of this chapter takes configuring the CMT2150-EM with the RFPDK as an example unless otherwise noted.
