6 AVR0000 0001B-AVR-10/09 3 Firmware Description 3.1 Prerequisites Before power-on the DUT by moving (Sw) to (ON) position, ensure the DUT is equipped with two AAA batteries. These batteries are to be placed at the back side of the DUT in the battery holder. Pay attention to the correct polarity of the batteries. 3.2 Power-On and Configuration There are two possibilities to power-on the DUT: 1. Without DUT configuration update, 2. Configuration mode (press (Button) during power-on). The next sections describe different ways to power-on a DUT in detail. 3.2.1 Without DUT Configuration Update The first choice is the standard selection to power-on the DUT. To select operation without radio transceiver configuration update, power-on the DUT by switching (Sw) to (ON) position. Do not press the (Button). There are two possible system configurations: • The very first power-on cycle (factory reset) enables operation at maximum TX output power and standard PSDU data rate. The DUT starts at test mode state “0”, refer to section 3.3. • All other power-on cycles remember the last radio transceiver configuration and test mode selection before last power-off cycle. If available, the LED indicating the reset state (LED_R) is on for a short time. Once this LED is off again, the microcontroller is waiting for a new (Button) command. 3.2.2 Configuration Mode Power-on the DUT in configuration mode allows either: • Reset to factory configuration, and, if required • Selection of TX output power and/or PSDU data rate, see references [1…2]. To do this, press and hold the (Button) before power-up the DUT. Once the DUT is powered on, the three state LED’s (LED_0 … LED_2) are switched on. Further handling of the (Button) determines the next configuration options. 3.2.2.1 Factory Reset If the (Button) is pressed during power-on and immediately released afterwards, factory reset configuration is loaded. If TX output power has to be switched to the minimum value do not release the (Button) within two seconds, for details refer to 3.2.2.2.
AVR0000 7 0001B-AVR-10/09 If no further (Button) activity is recognized, all three state LED’s are switched off 5 sec later. Continue to select the test mode as described in section 3.3. 3.2.2.2 Transmitter Output Power Selection If the (Button) is not released for about two seconds after power-on, the TX output power is set to the minimum possible value. This is indicated by switching off the three state LED’s (LED_0 … LED_2), and immediately after switching on state LED (LED_2). Now the (Button) has to be released to continue with PSDU data rate selection, or wait to leave the radio transceiver configuration menu 5 sec later. PSDU Data Rate Selection Release the (Button) either immediately or after TX output power selection, to enable the PSDU rate selection. This is possible independently on a previous TX output configuration. Each new (Button) press toggles the status LED’s similar to a binary counter between 1 through 4. Note, a new (Button) press event to select the PSDU data rate has to be performed within 5 sec after power-on or TX output power selection. Otherwise the configuration menu is left towards the Test Mode Selection, see section 3.3. The PSDU data rate is coded as follow: Table 3-1. Configuration Settings for 2.4 GHz Radio Transceiver State LED_0 LED_1 LED_2 Description 0 ON ON ON Factory reset value PSDU data rate = 250 kb/s 1 ON off off PSDU data rate = 250 kb/s 2 off ON off PSDU data rate = 500 kb/s 3 ON ON off PSDU data rate = 1000 kb/s 4 off off ON PSDU data rate = 2000 kb/s other other configurations are not available yet Once state 4 is reached, a new (Button) press starts at state 1. If, after power-on, perhaps TX output power selection and the first (Button) release, the (Button) is not pressed, as well as after each new (Button) press event to toggle the PSDU data rate, a 5 sec timer is started to automatically leave the radio transceiver configuration. Each new (Button) press resets the timer. Leaving the radio transceiver configuration is done automatically after about 5 sec and indicated by switching all state LED’s off. Note, the configuration menu is only accessible after power-on. Each new TX output power or PSDU data rate configuration requires a power cycle of the DUT.
8 AVR0000 0001B-AVR-10/09 3.3 Test Mode Selection After power-on, and optionally DUT configuration, the DUT is waiting for user input, in detail a (Button) press event. As long as no (Button) press occurs, the system remains in the state after power-on, see table below. Each new (Button) press event switches to the next state, for example after the initial state 0 (TRX_OFF) a (Button) press selects state 1, the radio transceiver starts to transmit a continuous wave carrier at channel 11. The TX output power used is according to the initial configuration. Table 3-2. Test Mode Selection Table State LED(1) Channel Blink Period RX/TX Modulation Burst Comment 0 1 2 [sec] 0 n/a TRX_OFF 1 B(2) 11(3) 2 TX no CW 2 B 18(3) 2 TX no CW 3 B 26(3) 2 TX no CW 4 B 11 1 TX yes(4) CW 5 B 18 1 TX yes(4) CW 6 B 26 1 TX yes(4) CW 7 B 11 0.5 TX yes(4) burst 100 ms 8 B 18 0.5 TX yes(4) burst 100 ms 9 B 26 0.5 TX yes(4) burst 100 ms 10 B 11 0.2 RX n/a n/a 11 B 18 0.2 RX n/a n/a 12 B 26 0.2 RX n/a n/a Notes: (1) Note the individual LED order for each RCB type. (2) B indicates LED is blinking, all other LED’s are off (3) Due to the radio transceiver architecture the unmodulated, CW TX RF frequency is at fTX,CW,noMod = fchannel – 0.5 MHz. But still within the modulation bandwidth of a modulated TX output signal. (4) These states using the PSDU data rate setting as configured after power-on, refer to 3.2. The selected channel is indicated by the corresponding LED, whereas the blinking period indicates the operating mode. A new (Button) press selects the next state. Once state 12 is reached, the next (Button) press switches to state 0, and therefore sets the radio transceiver part back into TRX_OFF (IDLE / Standby) state. It is not possible to change the PSDU data rate within this operating mode. Doing this requires a DUT power cycle as described in section 3.2.
AVR0000 9 0001B-AVR-10/09 3.4 Error Handling In test scenarios where external interferers or events are applied to check the robustness of the DUT, the device may not be able to continue with normal operation. Normal operation according to 3.3 is always indicated with one out of three LED’s blinking, whereas an error condition is visualized by all three state LED’s (LED_0 … LED_2) on. If a malfunction is indicated and the DUT is not damaged, it returns to normal operation after two seconds. The same holds for unexpected resets of the whole system, for instance during an ESD stress test. Such an event may cause an internal reset and the DUT immediately continues with normal operation according to the mode selected before. Furthermore, any behavior of the state LED’s different to 3.3 indicates a malfunction of either the microcontroller or radio transceiver part.
