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.


4271A–AVR–07/03

Figure 2-1. Joystick Input

Using the joystick one can move around in the menu shown in Figure 2-2, and edit val-ues, entering name, etc. Here are examples on how to enter your name.

2.2.1 Entering Your Name Using the Joystick:

1. Press the joystick up (“SCROLL UP”) to wake the AVR Butterfly. If “AVR BUT-TERFLY” is notscrolling over the display, press the joystick to the left (“EXIT SUB-MENU”) until it does.

2. Press the joystick down (“SCROLL DOWN”) three times, so the string “NAME” is displayed.

3. Press the joystick to the right (“ENTER SUB-MENU”). If this is the first time a name is entered, the string “ENTER NAME” will be displayed, otherwise the name already entered will be displayed and you have to press the joystick to the right (“ENTER SUB-MENU”) once more.

4. When “ENTER NAME” is displayed press center push (“ENTER”). If this is the first time you enter a name, the character “A” should be blinking in the right side in the display, otherwise the last character of the already entered name will blink.

5. Press the joystick up (“SCROLL UP”) or down (“SCROLL DOWN”) to get to the wanted character. Press the joystick to the right (“ENTER SUB-MENU”) to add a new character or press the joystick to the left (“EXIT SUB-MENU”) to remove a character.

6. When you have got all the characters, up to maximum 25, press center push (“ENTER”) to save this name. The name will now be displayed in the display. If the name is more than 6 characters long it will scroll over the display, otherwise it will be displayed static.

2.2.2 Entering Your Name Using a Terminal:

1. Connect a serial cable from the PC to the AVR Butterfly as described in Section 3.7 “Connect to PC”, Open a terminal on your PC (e.g. HyperTerminal) and con-figure the terminal to 19200 Baudrate, 8 Databits, none Parity and one stop bit.

2. Go through point 1, 2 and 3 above.


4271A–AVR–07/03

3. When the “ENTER NAME” is displayed press the joystick down (“SCROLL DOWN”), and “DOWNLOAD NAME” will be displayed

4. Press center push (“ENTER”) to activate the UART, and the text “WAITING FOR INPUT ON RS232” will be displayed.

5. Type your name in the terminal window on the PC (up to 25 characters) and save the name by pressing enter on your PC-keyboard. The name you typed should now be displayed in the AVR Butterfly display.

Note: The Auto Power Off feature is default enabled. It will turn off the LCD after default 30 minutes. This timeout can be changed or turned off. To wake the AVR Butterfly from SLEEP, press the joystick in the UP-position.

2.3 Menu System A menu system is established to be able to shift between the different modules in appli-cation in a efficient way.

4271A–AVR–07/03

Figure 2-2 shows the menu system of the application that comes with the AVR Butterfly.The column to the left displays the main menu: “AVR Butterfly”, “Time”, “Music” etc… Toshift between the alternatives in the menu, press the joystick UP or DOWN. To enter asub-menu, press the joystick to the RIGHT. To exit a sub-menu, press the joystick to theLEFT. To enter/adjust a value, press ENTER. E.g. when “Adjust clock” appears in theLCD, press ENTER to enter the adjust function.

2.4 Bootloader The AVR Butterfly comes with a bootloader which uses the self-programming feature inthe ATmega169. The bootloader combined with the integrated RS-232 level-convertermakes it possible to upgrade the application without any external hardware. It is basedon the Application Note AVR109: Self Programming AVR, but uses the new buffer loadmode for more efficient data downloading. AVR Prog, which is included in AVR Studio4,is used as PC frontend. The data is transmitted through the RS-232 interface. Connect aserial-cable from the PC to the AVR Butterfly as described in Section 3.7 “Connect toPC”.

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


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.

2. Do not use the AVRISP for In-System Programming, unless if the kit is pow-ered from an external power source.

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.


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.

Note: 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 the STK500 User Guide for information on how to use the STK500 front-end software in High-volt-age Programming mode.

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.


4271A–AVR–07/03

Figure 3-11. Joystick Schematic

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.


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.

4271A–AVR–07/03

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.
