atmel avr2160: REB233SMAD evaluation kit - quick start guide features this application note briefly describes how to set up and run the pre-flashed applications supplied with the atmel ? REB233SMAD evaluation kit. the atmel controller base board (cbb) is intended to serve as microcontroller platform for the atmel radio extender b oard (reb) family. t he reb connected to a cbb forms a full functional, battery powered and portable wireless node. the REB233SMAD evaluation kit is targeted fo r evaluating the ne w features (for example improved low power capabilities) of the atmel at86rf233 radio transceiver. 1 kit contents 2 atmel cbb 2 atmel REB233SMAD 4 sma antenna m35-s 2 usb adapter 1 quick start guide 4 aaa battery from left to right: 2 cbb, 2 REB233SMAD, 4 sma antenna, and 2 usb adapter. 2 board assembling 1. check/set power switch off at the two cbbs. 2. insert two batteries in each cbb. 3. mount the antennas to both rebs. 4. connect each reb to a ccb to create two reb-cbb assemblies. 8-bit atmel microcontrollers application note rev. 42000b-avr-04/12 expand1 connector
2 atmel avr2160 42000b-avr-04/12 off power switch on 3 simple range measurement the pre-flashed rf performance test suite in the atmel REB233SMAD evaluation kit assemblies features a simple range measurement application. each assembly operates in a standalone manner, and is able to transmit or receive data frames. a successful transmit or receive operatio n is indicated by a blinking led. 3.1 power up the assemblies apply power to both reb-cbb assemblies by switching on the power switch located on the top side of the cbb. the assemblies run a power-on check and indicate the su ccessful completion by switching on the second of the three leds. 3.2 run simple range measurement application choose one of the reb-cbb assemblies, and press button t1 to start the simple range measurement application. first, the reb-cbb initiates a connection and configuration procedure by sending broadcast frames and waiting for a response from the second re b-cbb. after a successful configuration, the reb-cbbs turn on led-d1 to indicate that status. the initiator starts to transmit data frames. each data frame transmission is indicated by blinking the tx status led-d2 . a successful data frame reception on the second node is indicated by blinking the rx status led-d3. the rx status led stops blinking if no data frames are received, such as when, for example, the node has left the communication range. data frame transmission can be stopped by pressing t1 once more on the node transmitting frames. the reb-cbbs are able to transmit and rece ive simultaneously. pressing button t1 on both nodes initiates each node to transmit fr ames. operating modes are indicated as: led-d1 a successful start-up, led-d2 in transmit and led-d3 in receive mode. note the node configuration gets lost when resetting or switching off the reb-cbb power supply; to restart, a reset or power cycle is required for both reb-cbb assemblies before pressing t1 on one (or both) reb-cbb(s). 4 packet error rate measurement the rf performance test suite features a packet error rate measurement (as defined by ieee ? 802.15.4), and allows to explore various radio transceiver features, radio transceiver registers, and performance by tuning with customized configurations. for this application, at least one reb-cbb as sembly needs to be connected to a pc. 4.1 board assembling 1. assemble the boards as described in chapter 2 . 2. make sure that the power switch on both assemblies is in the off position. 3. plug an usb adapter into a free usb port on your pc. interconnect this adapter and one of both reb- cbb assemblies via the 6-pin ribbon cable so that it fits the notch on the adapter and the colored stripe of the ribbon cable connects to pin 1 of the cbb header, usartd0. ? d3 d2 d1 t1 rx tx configuration status
