How to Operate the Pre-programmedApplication
The AVR Butterfly comes with a preprogrammed application. This section will gothrough the basics of this application. The firmware can be downloaded from the AVRButterfly web-site, http://www.atmel.com/products/AVR/butterfly.
2.1 Included Firmware
These modules are preprogrammed with the AVR Butterfly:
! Bootloader code
! Application code
– State machine
– Features included - Name-tag- Clock (date)- Temperature measurements- Light measurements- Voltage readings- Play tunes/melodies- Auto power save- Adjust LCD contrast
– More functions can be added later on- Calculator- Reminder function- Alarm (daily alarms, kitchen timers, etc…)- Play melodies and displaying the text (Karaoke-function)- With the 4Mbit dataflash one can store large amount of data. (Someexamples: AVR Info Bank (Basic of all AVR-parts); your local bus-table;melodies, etc.)
Note: The application can be upgraded without any external hardware, due to the inte-grated level-converter and the Self-programming feature.
2.2 Joystick Input To operate the AVR Butterfly a joystick is used as user input. It operates in five direc-tions, including center-push, see Figure 2-1.
AVR Butterfly User Guide -3

Section 3
Using the AVR Butterfly
This section describes in detail how to use the AVR Butterfly evaluation kit.
3.1 Connectors Some of the I/O-pins on the ATmega169 are available on the connectors of the AVRButterfly. These connectors are for communication, programming and input to the ADCof the ATmega169.
Figure 3-1. Connectors
3.2 Programming the AVR Butterfly
In addition to using the pre-programmed bootloader with AVR Studio, the ATmega169on the AVR Butterfly can be programmed using SPI, High-voltage Parallel Programmingand the JTAG interface.
3.2.1 In-System Programming
AVR Butterfly User Guide -11
4271A–AVR–07/03
Figure 3-2. In-System Programming
To program the ATmega169 using ISP Programming mode, connect a 6-wire cablebetween the ISP6PIN connector on the STK500 board and J403 the ISP connector onthe AVR Butterfly as shown in Figure 3-2. This device can be programmed using theSerial Programming mode in the AVR Studio4 STK500 software. Instead of soldering ina ISP-header, one can make contact just by pressing the header to the footprint. Makesure that pin 1 on the STK500 match with pin 1 on the AVR Butterfly. See Figure 3-3 forthe pinout of the ISP Connector.
Figure 3-3. ISP Connector, J403
Notes: 1. More information about the STK500 can be found in the STK500 User Guide, which is available at the Atmel web site, www.atmel.com. See STK500 User Guide for information on how to use the STK500 front-end software for ISP Programming.

3.2.2 High-voltage Parallel Programming
It is possible to program the ATmega169 through the High-voltage Parallel Program-ming interface. However this requires to move two resistors on the PCB. High-voltageParallel Programming is only meant to be used in the worst case scenario, where bothSPI and the JTAG interface are disabled.
To make the parallel programming work, R203 must be placed where the R204 shouldbe, and R404 must be placed where the R403 should be according to Figure 3-4. Seethe Assembly Drawing in the 7 Complete Schematics
Figure 3-4. Ohm Resistors
Connect RESET, BSEL2 and XTAL1 from the STK500 to respectively pin 6, pin 8 andpin 10 on the JTAG (J402) connector on the AVR Butterfly. See Figure 3-5. The JTAGconnector must be mounted on the back side of the AVR Butterfly.
Figure 3-5. Reset, BSEL2 and XTAL1 cables
Connect PROG DATA and PROG CTRL from the STK500 to respectively PORTB andPORTD on the AVR Butterfly. Make sure that pin 1 on the STK500 connects to pin 1 onthe AVR Butterfly.
AVR Butterfly User Guide -13
4271A–AVR–07/03
Figure 3-6. PORTB and PORTD
See the Schematic and the Assembly Drawing in the 7 Complete Schematics for furtherdetails.
The device can now be programmed using the High-voltage Programming mode in AVRStudio STK500 software.
During programming there will be some noise from the piezo element, and some flicker-ing on the LCD, this because PORTB and PORTD are connected to theses modules.
Figure 3-7 shows the pinout for the I/O port headers PORT B and PORT D.
Figure 3-7. PORT B and PORT D
Note: When the AVR Butterfly is configured in High-voltage Parallel Programming mode, the JTAG interface will not work, neither will the external crystal, causing the pre-programmed application that comes with the AVR Butterfly to not oper-ate correctly.

3.3 JTAG Figure 3-8 shows how to connect the JTAG ICE probe to the AVR Butterfly.
Figure 3-8. JTAG connector
Note: The JTAG connector must be mounted on the back-side of the AVR Butterfly.
The JTAG connector is used for the ATmega169 built in JTAG interface. The pinout ofthe connector is shown in Figure 3-9 and is compliant with the pin out of the JTAG ICEavailable from Atmel. Connecting a JTAG ICE to this connector allows On-chip Debug-ging of the ATmega169.
More information about the JTAG ICE and the On-chip Debugging can be found in theAVR JTAG ICE User Guide, which is available at the Atmel web site, www.atmel.com. Note: Pin 7, NC(VCC) is the Vsupply pin for the JTAG. This pin is not connected
because the JTAG would draw power from the battery on the AVR Butterfly.
Pin 8, NC(BS2) and the pin 10, GND(XTAL1) can be modified serve as the BS2 andXTAL1 pin during High-voltage Parallel Programming. For more details see 3.2.2 High-voltage Parallel Programming.
Figure 3-9. JTAG Connector
Note: It is highly recommended to apply external power (3,1 – 4,5V), when using the JTAG to save the battery. See Figure 3-10 for how to connect external power.

Make sure to disable the OCD-fuse after a debugging session, due to power consumption. The OCD-fuse will be disabled if pressing on the “Stop Debug-ging” button in AvrStudio4, before disconnecting the JTAG ICE probe from the AVR Butterfly.
Figure 3-10. External Power
External power can be applied at pin 9 and 10 at both PORTB and PORTD, see Figure3-7 for the pinout.
If the JTAG are not in use, the four JTAG pins can be used as input for the ADC chan-nels ADC[4:7]. See the ATmega169 datasheet for more information, available fromwww.atmel.com
3.4 LCD Display The LCD display on the AVR Butterfly is the same as used on the STK502 availablefrom Atmel. The connections between the ATmega169 and the LCD are also the same.See the STK502 User Guide at www.atmel.com for more information about the LCD dis-play, and the LCD bit-mapping.
For more information on how to write software for the LCD-display see application note“AVR064: STK502 – A Temperature Monitoring System with LCD Output” and applica-tion note “AVR065: LCD Driver for the STK502 LCD”.Note: Touching the LCD-pins will affect the segments on the LCD.
3.5 Joystick The AVR Butterfly has a miniature joystick for input from user. It operates in five direc-tions, including centre-push. The common line of all directions is GND. This means thatinternal pull-up must be enabled on the ATmega169 to detect the input from the joystick.

3.6 Sensors The AVR Butterfly has two on-board sensors which makes it possible to measure bothtemperature and light. In addition is has a voltage-divider that is used to measure volt-ages from 0 to 5V.
3.6.1 Temperature Sensor The temperature sensor can be found at the back side of the AVR Butterfly. See Figure3-12.
AVR Butterfly User Guide -17
4271A–AVR–07/03
Figure 3-12. Temperature Sensor
An NTC (Negative Temperature Coefficient)-thermistor is used to measure the tempera-ture. An NTC-thermistor is characterised by the fact that when the temperature goesdown the resistance goes up. Using a voltage divider and reading the voltage over thethermistor through the ADC-channels on the ATmega169, the temperature in can becalculated. Equation for calculating the temperature in Celsius is shown in Figure 3-13.

3.6.2 Light Sensor The light sensor is located at the front of the AVR Butterfly, over the LCD. See Figure3-15.
Figure 3-15. Light Sensor
An LDR (Light Dependent Resistor) is used to measure the light. An LDR is character-ised by the fact that when the light decreases the resistance goes up. Using a voltagedivider and reading the voltage over the LDR through the ADC-channels on theATmega169, the light can be calculated.
3.6.3 Voltage Reader The AVR Butterfly is capable of reading voltages from 0V to 5V. The input must be con-nected to the pins shown in Figure 3-16. Using a voltage divider and reading the voltageover the resistors through the ADC-channels on the ATmega169, the applied voltagecan be calculated. The accuracy is about 0,1V.
Figure 3-16. Voltage Readings
Note: Do not apply voltages above maximum 10V
3.7 Connect to PC The AVR Butterfly has an on-board level-converter for the RS-232 interface. This meansthat no external hardware is required to reprogram the AVR Butterfly using the self pro-gramming feature in the ATmega169. Figure 3-17 shows how to connect a serial-cableto the AVR Butterfly. The integrated RS232 level converter operates down to 2.0V sup-ply voltage.

3.9 External DataFlash
An external dataflash is provided with the AVR Butterfly. This is the 4-megabit serialDataFlash from Atmel, type AT45DB041B. More information about the DataFlash canbe found in the datasheet available at the Atmel web site:http://www.atmel.com/products/DataFlash/
The DataFlash is connected to the SPI interface. This means that in addition to commu-nicate with the ATmega169 on the AVR Butterfly, it can also be accessed externallythrough the ISP connector. Note: If the DataFlash is to be accessed externally, the ATmega169 on the AVR But-
terfly must be set to disable its own SPI interface to avoid contention on the interface.
