Page 3: Introduction
INTRODUCTION The CY3635 N:1 development kit was designed to demonstrate a “many to one” protocol using the WirelessUSB™ family of radios. This DVK will support up to 512 Sensor nodes connected to a single Hub. The N:1 protocol has been designed to operate in noisy environment and uses a combination of frequency agility, coding gain, and packet error detection and correction in order to provide reliable wireless communication. -

Page 5: N:1 Software Application
N:1 SOFTWARE APPLICATION With the network up and running, the N:1 Application screen should look similar to the following screen capture. Figure 2: Software Application Screen Capture The Sensors initiate communication with the Hub. This allows for the Sensors to optimize their power conservation. When they are not communicating, they are in a low-power state waiting for a hardware wake-up event or the sleep timer to expire. -

Each element in the pane is described below. 4.1.1 Sensor Properties Group Box The Sensor ID field shows the Device ID assigned to the selected Sensor. The Sensor Name edit control displays a user-definable friendly name for the Sensor (e.g. -

When communication is established the button will change to the Connected state. • Capture Message Log to File – When enabled, all output to the Message Log Pane is also written to a file. - Page 11 a Hub before it can successfully transmit data again. In the N:1 DVK, a Factory Reset will need to be performed. • Bind On/Off – When Bind is on, the Hub spends half of its time servicing the Bind channels which removes bandwidth from servicing normal network traffic.

Page 12: Control Dialog
Control Dialog In addition to the main application window, a special Control Dialog is provided that is designed to monitor temperature Sensors and turn an actuator on and off. We will use an HVAC control system as our example when describing the Control Dialog. Air conditioners, heaters, and electronic dampers will be controlled based on the wireless temperature information collected by the N:1 Application. -

environment and allow their readings to settle. Then select the Sensors to be calibrated and then click the Calibrate button. This process takes all of the current temperature readings for the Sensors and computes an average temperature. That average temperature is then compared to each existing Sensor reading and an offset is created and stored in the Windows registry. -

5.1.2 DIP Switch Configuration The DIP Switches can be used as general purpose switches during run- time. If S1 is pressed during Reset, the DIP switches are used to access special modes as noted in the following table: The kit is shipped with the DIP Switches set to 0000.

The “Clear Non-Volatile Storage” function is used to erase the bind parameters stored in FLASH on the Hub and Sensor. On the Hub, this function also clears the non-volatile FRAM that contains the Device ID table. When the Erase Bind parameters is complete, the firmware will flash the red LED indicating that the procedure has been completed and will need to be reset by pressing the Reset Button to resume normal operation. - Page 20 Sensor Seeded Bind Procedure Use the following procedure to add a new Sensor to a new or existing network via the Seeded Bind method: Step Device Description Sensor Set the DIP Switches to desired network from Table Sensor Press and hold both the S2 “RESET” button and the S1 “BTN”...

The subset was chosen to fit in three DIP switches and work with both 64cpb and 32cpb. To perform a Seeded Bind, set the first three DIP switches to the desired setting based on the table below. S1 needs to be depressed when the PSoC comes out of reset in order for the firmware to perform a Seeded Bind based on the dipswitch setting. -

Note: Serial debug output may change the PSoC radio timing. Adding extensive debug output is not recommended as it may alter the system timing causing devices to timeout before data can be transmitted. Network Latency Tools (Test Mode 1&2) By default, the Sensor firmware supports two 100 packet latency tests. Both tests will transmit 100 packets to the Hub while recording the total number of packet retries and the latency from when the packet was sent to when an acknowledgement is received from the Hub. -

WirelessUSB Listener Tool To assist developers in debugging WirelessUSB N:1 systems, Cypress has created the WirelessUSB Listener Tool which is available separately (CY3632L). The Listener Tool works by listening to WirelessUSB traffic on a given channel and PN code. It passes the captured packets to a Host computer through a full-speed USB connection. - Page 26 The following figure shows a sample screen capture of the WirelessUSB Listener Tool.
