4 2. General Information The Atmel AVR XMEGA-E5 Xplained kit is intended to demonstrate the Atmel AVR ATxmega32E5 microcontroller. Figure 2-1 shows the available feature on the board. Figure 2-1. Overview of the XMEGA-E5 Xplained kit. Header J1 Power measurement header USB Header J3 connector PDI header Power & Status LEDs Mechanical button SW0 User LEDs 0 and 1 Quadrature encoder selection switch SW103 Mechanical button SW1 Quadrature encoder SW102 Light sensor Header J 2 OLED display Header J4 2.1 Preprogrammed firmware The ATxmega32E5 on the XMEGA-E5 Xplained is pre-programmed with a default firmware. The detailed description of the software is available in the AT02657 XMEGA-E5 Xplained Software User Guide. Project and source files are available within Atmel Studio and Atmel Software Framework. 2.2 Power supply The kit needs an external power supply that can deliver 5V and up to 500mA. The actual current requirement for the board is much less than 500mA but in order to be able to power optional expansion boards this margin is recommended. The power can be applied to the board either via the USB connector or on pin 10 on the header J3. The USB connector is the preferred input because it is then possible to connect expansion boards on top of the J3 header. The 5V (USB supply voltage) is regulated down to 3.3V with an onboard LDO regulator, which provides power to the entire board. Expansion top boards that require 5V will get this from the header J3 pin 10. 4
5 2.3 Measuring the Atmel AVR XMEGA power consumption As part of an evaluation of the Atmel AVR ATxmega32E5, it can be of interest to measure its power consumption. Because the XMEGA has a separate power plane (VCC_MCU_P3V3) on this board it is possible to measure the current consumption by measuring the current that is flowing into this plane. The VCC_MCU_P3V3 plane is connected via a jumper to the main power plane (VCC_P3V3) and by replacing this with an ampere meter it is possible to determine the current consumption. To locate the power measurement header, please refer to Figure 2-1. Warning: Do not power the board without having the jumper or an ampere meter mounted since this can cause latch-up of the Atmel AVR ATxmega32E5 due to current flow into the I/O pins. 2.4 Communication through the USART-to-USB gateway The ATxmega32E5 USART is connected to a USART on the Atmel AT32UC3B1256. The ATxmega32E5 USART is communicating at baud using one start bit, eight data bits, one stop bit, and no parity. When the AT32UC3B1256 device is enumerated (connected to a PC). The data transmitted from the ATxmega32E5 is passed to a (virtual) COM port. This means that it is possible to use a terminal program on a PC to receive the transmitted data. Similarly data transmitted from the PC COM port is passed to the ATxmega32E5 USART through the gateway. 2.5 Programming the kit The kit can be programmed using an external programming tool. How a programmer can be connected to the kit is described in Section
6 3. Connectors The Atmel AVR XMEGA-E5 Xplained kit has four 10-pin, 100mil headers and one 6-pin 100mil header. The 6-pin header is used for programming the Atmel AVR ATxmega32E5, and the 10-pin headers are used to access spare analog and digital pins on the Atmel AVR XMEGA (expansion headers). 3.1 Programming headers The XMEGA can be programmed and debugged by connecting an external programming/debugging tool to the PDI header shown in Figure 2-1. The grey XMEGA PDI adapter must be used on the Atmel AVR JTAGICE mkii probe when connecting to the XMEGA- E5 Xplained board. The green standoff adaptor nr.3 (ref.a ) has to be used on the Atmel AVR ONE! probe when connecting to the XMEGA-E5 Xplained board. Table 3-1. XMEGA programming and debugging interface PDI. Pin on programming header PDI 1 DATA 2 VCC CLK 6 GND 3.2 I/O expansion headers The Atmel AVR XMEGA-E5 Xplained headers J1, J2, J3, and J4 offer access to the I/Os of the microcontroller in order to expand the board, for example by mounting a top module onto the board. The header J1 offers digital communication interfaces like UART, TWI and SPI. Table 3-2 shows how the Atmel AVR XMEGA is connected to the header. Note: When using TWI please note that no pull-ups are mounted on the board from the factory, so it is required to enable the internal pull-ups of the device. Table 3-2. Expansion header J1.

9 4. Peripherals 4.1 Mechanical buttons Two mechanical buttons are connected to Atmel AVR XMEGA. All buttons have no external pull-ups so user has to activate internal pull-ups in order to use them. When a button is pressed it will drive the I/O line to GND. Table 4-1. Mechanical button connection. Pin on XMEGA PD0 PD2 Silkscreen text on PCB SW0 SW1 4.2 LEDs There are two yellow LEDs available on the board that can be turned on and off. The LEDs can be activated by driving the connected I/O line to GND. Table 4-2. LED connections. Pin on XMEGA LED PD4 Yellow LED0 PD5 Yellow LED1 One green LED (power indicator) and one red LED (status) are also present inside the same package and therefore the colors can be mixed to orange when both are activated. Those two LEDs are controlled via the Board Controller and user has no access to them. 4.3 Quadrature encoder The Quadrature Encoder (SW102) is made of one mechanical button and two outputs. These outputs are connected to a mechanical switch (SW103) which enables to either connect them to the XMEGA pins or let them accessible on J3 header. Table 4-3. Quadrature encoder connections.

It has a resolution of pixels. In the design the display is connected via a SPI based interface. Detailed information about the display can be obtained from the display datasheet. The connection between the MCU and the OLED display is shown in Table

The measurement circuitry is configured to measure the illuminance from ~10 to ~900lx when the internal VCC/1.6 reference is used. The data in Table 4-6 which shows the relationship between illuminance and output voltage of the sensor circuitry is generated based on the symbols and formulas in Table 4-5. Table 4-5. Symbol description for illuminance calculation. Symbols ICA Ev I U R Ev = 100 I / ICA I = U / R U = (Ev R ICA) / 100 Description Calibrated sensor responsitivity at 100lx. This is 50µA according to the sensor datasheet Illuminance Current through the sensor Output voltage of the sensor circuitry that is provided to the ADC Series resistor of the sensor circuitry. 4.7kΩ has been chosen in this design Illuminance is calculated based on the relation of the actual current through the sensor to the calibrated value at 100lx Since the ADC measures the voltage across the series resistor of the sensor circuitry it is necessary to calculate the voltage based on the current Based on the current and the illuminance the output voltage of the sensor circuitry can be calculated Table 4-6.

All interfaces can be used to communicate between the devices, but only the USART is implemented by default on the board controller. Table 4-7. ATxmega32E5 and board controller communication interface.

This represents the RX and TX on the ATxmega32E5. The RX is connected to TX on the other device, and vice versa. 2. These TWI signals can be reconnected by placing a 0 ohm resistor or a solder drop on R408 and R409 footprints. 3. These SPI signals can be reconnected by placing a 0 ohm resistor or a solder drop on R410, R411, R412 and R413 footprints 11
