CHAPTER 1 Matrix Evaluation Kit Overview 1.1 Description The evaluation kit provides the end user the ability to quickly become familiar with the Matrix module. Included in the kit are two Matrix modules and a quick start guide to demonstrate the communication link between the two modules. Also included is a GUI interface referred to as the Matrix Evaluation Test Tool (TT) to quickly communicate with the RF modules. The Evaluation software demonstration is presented in Chapter 4.
CHAPTER 2 Quick Start 2.1 Board Description The Matrix module is a 2.4GHz 802.15.4 data transceiver module based on the Chipcon CC2430 Low Power 8051/Transceiver device. It provides enhanced range performance with either a 10mW or 100mW* power amplifier. The module also contains an integrated PCB trace antenna. Power is supplied by the host device through the interface connection in accordance to the operating voltage requirements with a nominal operating voltage of +3.3V.
2.2 Operational Overview The quick start demonstration presented in this chapter is referred to as the ping pong test. The ping pong test allows an end user to easily verify communication between two transceivers and get a feel for the quality of the link via feedback of the flashing LEDs. Operation involves two boards, with one designated as a master device and the other as a slave device. The master periodically transmits packets to the slave.
2.2.2 Master/Slave Selection Master device setup: 1. Press reset button (S1), see Figure 3-1 location 5, and user button (S3), see Figure 3-1 location 6, on Interface Board simultaneously. 2. Release reset button (S1) on Interface Module. 3. Wait until yellow LED (LED2) is lit, then release reset button (S1). Slave device setup: 1. Press reset button (S1) and user button (S3) on Interface Board simultaneously. 2. Release reset button (S1) on Interface Module. 3.
2.2.5 Channel Changing (can only be peformed if boards have been associated) While in the ping pong mode, the current channel can be changed to one of four other unique channels (four channels total). This is accomplished by holding the push button for approximately two seconds, at which point the yellow LED (LED2) will be lit steady. Once the push button is released, the current channel option number (one through four) is displayed by a series of flashes on the red LED (LED3).

4.3 Setting Up and testing a Wireless Link Operational testing of the Matrix RF module requires at least 2 units in order to establish a link. One unit will be the initiator and the other will be the responder. In order for a link to be established it is necessary to setup the transceiver’s RF Channel, long or short address, and PAN ID. Link testing may be performed in either a single ended or a round trip fashion.
Device 2 (Refer to Figures 4-11 and 4-12) 1. Set PAN ID to 100 (IDs Page). 2. Set short address to 2 (IDs Page). Note to use long addressing set short address to 65,535. 3. Disable Acknowledgements/Retries (RF Settings Page). 4. Disable Receive All RF Messages (RF Settings Page). 5. Set to RF Channel 23 (RF Settings Page). 6. Set transmitter power setting to 31 (RF Settings Page). 7. Set Short Destination address to 1 (Located Upper left corner of TT). 8.
Figure 4-11. ID Settings for Device 2. Figure 4-12.
Operational Description Place the 2 units in physically separate locations and apply power to them. The statistics will clear when power is cycled, but they will need to be cleared manually after each test if power is not cycled. Connect each individual PC serial port to each of the units and verify the correct destination address is typed in the address field on the top of the test tool. Type a short message into the “RF Data” window of the initiating device. The message can be any text or numbers.
CHAPTER 5 Matrix/Zigbee Ready Module Input/Output 5.1 Overview There are a total of 12 user input/output pins on the Matrix module, all of which can be configured as digital inputs or outputs. Of the 12 configurable digital I/O pins, 8 of them can also be configured as analog inputs. 5.2 Digital Inputs/Outputs There are 12 configurable digital input/output pins that can be programmed to be either inputs or outputs.
5.3 Analog Inputs There are 8 pins that can be configured as analog inputs. Refer to Table 4-2 for the specific I/O pin capabilities. Using the analog input pins consists of the following: Configuring the pins Select direction as analog input. Select the analog-to-digital converter settings for each specific pin configured as an analog input (refer to Section 4.2.7).
CHAPTER 6 Matrix Application Guide 6.1 Overview This Chapter describes the essentials for using the host protocol to configure and use a Matrix module in an application. Please refer to Host Protocol Document for Further Details on messaging. 6.1.1 Host Protocol The host protocol that is used to communicate with a Matrix module is a simple binary based protocol.
Communication Parameters There are six configuration parameters used to setup the Matrix module for communications, which are outline below. 1. Set PAN ID – The Personal Area Network (PAN) ID is used to establish networks of transceivers. Only devices with the same PAN ID will communicate with one another. 2. Set Transceiver Address – The Transceiver Address is used to differentiate transceivers within a network. Each transceiver should be configured with a different address.
2. Set I/O Sleep State – This message defines the state that the I/O pins will be put into when the low power sleep mode of operation is requested for the module. Similar to the “Set I/O Configuration” message, the direction of the pin, whether or not the pull-up or pulldown resistors are enabled for input pins, and the output value for output pins can be configured. Upon exiting sleep mode the pins will be configured back to the state they were in prior to entering sleep mode. 3.
Diagnostics and Feedback Parameters There are two configuration parameters used to setup diagnostics and user LED feedback which are outlined below. 1. Set Debug Mode – Setting the debug mode allows the host application to configure what debug information gets displayed on the three mode pins when the mode pins are in their default state. The default state for the mode pins is that none of the pins are externally pulled-down.
Host Messages 1. Set PAN ID < 0x07 0x01 0x07 0x01 0x64 0x00 0x6D 0x04 > 2. Set Transceiver Address < 0x0F 0x01 0x0F 0x03 0xF4 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0xFF 0xFF 0x06 0x04> 3. Set RF Channel < 0x06 0x01 0x06 0x05 0x12 0x1E 0x04 > 4. Disable Receive All RF Messages < 0x06 0x01 0x06 0x07 0x00 0x0E 0x04 > 5. Enable Acknowledgements and Retries < 0x06 0x01 0x06 0x09 0x01 0x11 0x04 > 6. Set Transmit Power Level < 0x06 0x01 0x06 0x0F 0x1F 0x35 0x04 > 7.
6.1.3 RF Messaging Overview The Matrix module provides a versatile command set for communications between modules. Depending on the application’s requirements, either short or long address modes can be used. Short addressing mode uses a two byte transceiver address, while long addressing mode uses eight byte transceiver addresses.
Receive All (Feature Currently Not Available) Receive all mode is used as a diagnostic mode in which a transceiver can listen to and receive all of the messages from any device that is communicating on the same PAN ID and RF channel. Messages with long and short addressing types will be received, and when a message is received it is sent out the host serial port with a message type of 0xA9. In receive all mode it is not possible to transmit messages to other transceivers.
Host Send Mode (Host -> Txcvr A) Short Short Short Short Long Long Long Long Addressing Mode (Txcvr A -> Txcvr B) Txcvr A Txcvr B Short Short Long Long Short Short Long Long Short Long Short Long Short Long Short Long Host Receive Mode (Txcvr B -> Host) Source Destination Short - (Note 1) Long - (Note 1) - (Note 2) Short - (Note 2) Long Short - (Note 1) Short - (Note 1) - (Note 2) Long - (Note 2) Long Broadcast Ok Ok Ok Ok - Table 6-1.
6.1.4 Example Messaging For all of the following examples it is assumed that the PAN ID and RF channel are set to be the same on both Matrix modules. Also the messages will originate in the host connected to transceiver A and they will be sent to transceiver B. The data contained in the message will be 0x01, 0x02, 0x03. All received messages have a Link Quality Indication (LQI) of 200 (0xC8).
Short To Long Addressing The following example will show details of communications between two Matrix modules with transceiver A configured to use short addressing and transceiver B configured to use long addressing.
Long To Long Addressing The following example will show details of communications between two Matrix modules both configured to use long addressing.
configured as digital inputs contain any meaningful information. A zero indicates a low signal is applied to the input, while a one indicates a high signal is applied. Example: Digital Inputs = P0_6, P0_5, P1_7, and P1_1.
