The supply current of the AS3900 can be measured. The SDI –Interface from the microcontroller can be replaced by an proprietary solution Serial Digital Interface DATA Input Serial Digital Interface Clock Serial Digital Interface Enable Serial Digital Interface DATA Output Microcontroller Clock Output External Interrupt for Microcontroller Power On Reset Output How to easily get started with the AS3900 demo kit? • Allocate 1 board as Master and 1-8 boards as Client via switch “D”. • Select for each Client a unique ID via the dip switches “E”. • Connect the Master to the PC via the provided USB Cable on “G” and start the GUI. • Turn on all board. For the Master turn the ON/OFF – switch “F” to USB. For the Client turn the switch “F” to BATT. If the Master is not connected to the PC, supply the board from battery also. When turning on the boards all indication-LEDs flash up once. • Press the PAIR – button “C” at all Clients, in order to prepare the Clients for the pairing procedure. The PAIR led is blinking red. • Press the PAIR –button “C” at the Master. All Clients will get visible on the GUI. All PAIR - LEDs are blinking green. • Press the WAKEUP – button “B” at all Clients, in order to prepare the Clients for the data transmission. • Press the WAKEUP – button “B” at the Master to start the communication. All light sensors get visible at the GUI. All WAKEUP - LEDs are blinking green. • Darken the light sensor “A” at the Clients. The current brightness of the sensor is visualized on the GUI. www.austriamicrosystems.com Revision 1.00 3-8 AS3900 - Demo Board Manual 27MHz Low Power FSK Transceiver Install the GUI: 1. 2. 3. Execute the AS39xxx_EvalSW.msi Follow the installation guide Run the GUI
AS39XX_EvalSW.exe Note: If the Master is correctly connected, the USB field in the lower left corner is green. Afterwards the GUI is ready to run the following procedure to establish the network. How to execute a Firmware Update: 1. 2. 3. Connect AS3900 Demoboard with the PC and turn on the board (Set switch “F” to USB) Go to Help
Firmware Update (Ctrl + F) Select and load latest Hardware (*.bin – File) Note: After a Firmware Update it is recommended to restore the default settings from flash, in order to get a working setup. Go to the Expert Mode and press the button “restore default settings”. www.austriamicrosystems.com Revision 1.00 4-8 AS3900 - Demo Board Manual 27MHz Low Power FSK Transceiver Operational sequence This demo board comes with one antenna, one 3V battery and one USB-cable. Prepare the Hardware 1. Drive the IC on the demo board only with the recommended settings and values as described in the datasheet. If not present get the datasheet for the AS3900 from www.austriamicrtosystem.com. 2. First connect the power supply via connector “G” to a powered USB port or insert the provided 3V battery. Power on the Demoboard by turning the switch “F” to USB or BATT. The Master is recommended to be supplied from USB. The Client is supplied from the 3V battery. To power down the system turn the switch “F” into its middle position (OFF). 3. Select one Demoboard as Master and at lease one Demoboard as Client at Switch “D”. Make sure not to have more than one Master. 4. Select for each Client a unique ID via the Dip Switches “E”. Make sure not to have Clients with the same ID. PAIR the Clients to the Master 1. Press the “PAIR” Button “C” at all Clients. The “PAIR” Button is blinking red. 2. Press the “PAIR” Button “C” at the Master. The Master starts the communication and the Clients send their IDs. If the Master gets valid IDs the PAIR LED switch from blinking red to blinking green. This mean, that the Master has recognized at least one Client for the network. After a handshake the Clients start to blink green as well. 3. If not all Clients are paired at the first time, press the “PAIR” button at the master again, until all Clients are blinking green. 4. The GUI at the Master shows all valid Clients with their appropriate address. (Dip Switch + 1) WAKEUP the Clients to start the communication After the clients are successfully paired, they are automatically switched into a Sleep Mode. In order to start the data communication, the Clients need to be woken up: 1. Press the “WAKEUP” Button “B” at all Clients. The “WAKEUP” Button is blinking red. As soon as the communication is running the WAKEUP Button is blinking green. 2. Press the “WAKEUP” Button “B” at the Master. The Master starts again the communication and the Clients begin to send data. As soon as the Master receives valid data, the WAKEUP Button at the Master is blinking green as well. Transmitted, received and lost packages are indicated via LEDs “TRANS-PACK”, “RCV-PACK” and “LOST-PACK”. 3. The brightness sensor can be seen on the GUI (Master) and actual data can be changed at the Clients by shading the sensor. 4. Once the connection to one Client is lost, the appropriate Client stops blinking “TRANS-PACK” and “RCV-PACK”. If the Client is again very close to the Master the connection is re-established automatically. “TRANS-PACK” and “RCV-PACK” starts to blink again. Note: Pressing the WAKEUP Button “B” at the Master, starts and stops the communication. If there are questions do not hesitate to contact us.
