E.g. when “Adjust clock” appears in the LCD, press ENTER to enter the adjust function. 2.4 Bootloader The AVR Butterfly comes with a bootloader which uses the self-programming feature in the ATmega169. The bootloader combined with the integrated RS-232 level-converter makes it possible to upgrade the application without any external hardware. It is based on the Application Note AVR109: Self Programming AVR, but uses the new buffer load mode 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 a serial-cable from the PC to the AVR Butterfly as described in Section 3.7 “Connect to PC”. Figure 2-3. AVR Prog in AVRStudio4 2.4.1 Upgrade the ATmega169 AVR Butterfly User Guide A jump to the boot section can be done from the application, “Options>Bootloader>Jump to Bootloader”, see Figure 2-2, or just reset the ATmega169 by shortcut pin 5 and 6 on J403 the ISP connector, (after a reset the ATmega169 will start in the boot section). See Figure 3-3 for the pinout of the ISP-connector. Nothing will be displayed on the LCD while in boot section. Press and hold the joystick in the ENTERmodus while starting AVR Prog. When AVR Prog starts, release the joystick. Find the *.hex file you want to program with the “Browse” button, and press “Program”. See that “Erasing Device”, “Programing” and “Verifying” goes “OK”, this is done automatically. After upgrading the application, press the “Exit”-button in AVR Prog in order to leave programming mode in the ATmega169 bootloader. -11 4271C–AVR–04/05 Figure 2-4.

These connectors are for communication, programming and input to the ADC of the ATmega169. Figure 3-1. Connectors 3.2 Programming the In addition to using the pre-programmed bootloader with AVR Studio, the ATmega169 on the AVR Butterfly can be programmed using SPI, High-voltage Parallel Programming AVR Butterfly and the JTAG interface. 3.2.1 In-System Programming AVR Butterfly User Guide -15 4271C–AVR–04/05 Figure 3-2. In-System Programming To program the ATmega169 using ISP Programming mode, connect a 6-wire cable between the ISP6PIN connector on the STK500 board and J403 the ISP connector on the AVR Butterfly as shown in Figure 3-2. This device can be programmed using the Serial Programming mode in the AVR Studio4 STK500 software. Instead of soldering in a ISP-header, one can make contact just by pressing the header to the footprint. Make sure that pin 1 on the STK500 match with pin 1 on the AVR Butterfly. See Figure 3-3 for the pinout of the ISP Connector. Figure 3-3. ISP Connector, J403 1 2 PB3 VCC_EXT PB1 PB2 RST GND ISP 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 powered from an external power source. -16 4271C–AVR–04/05 AVR Butterfly User Guide 3.2.2 High-voltage Parallel Programming It is possible to program the ATmega169 through the High-voltage Parallel Programming interface. However this requires to move two resistors on the PCB. High-voltage Parallel Programming is only meant to be used in the worst case scenario, where both SPI and the JTAG interface are disabled. To make the parallel programming work, R203 must be placed where the R204 should be, and R404 must be placed where the R403 should be according to Figure 3-4. See the 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 and pin 10 on the JTAG (J402) connector on the AVR Butterfly. See Figure 3-5. The JTAG connector 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 and PORTD on the AVR Butterfly. Make sure that pin 1 on the STK500 connects to pin 1 on the AVR Butterfly. AVR Butterfly User Guide -17 4271C–AVR–04/05 Figure 3-6. PORTB and PORTD See the Schematic and the Assembly Drawing in the 7 Complete Schematics for further details. The device can now be programmed using the High-voltage Programming mode in AVR Studio STK500 software. During programming there will be some noise from the piezo element, and some flickering 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 1 2 1 2 PB1 PD0 PD1 PB2 PB3 PD2 PD3 PB4 PB5 PD4 PD5 PB6 PB7 PD6 PD7 PB0 GND VCC_EXT PORTB Note: -18 4271C–AVR–04/05 GND VCC_EXT PORTD 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 operate correctly. AVR Butterfly User Guide Note: 3.3 JTAG 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-voltage Programming mode. 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 of the connector is shown in Figure 3-9 and is compliant with the pin out of the JTAG ICE available from Atmel. Connecting a JTAG ICE to this connector allows On-chip Debugging of the ATmega169. More information about the JTAG ICE and the On-chip Debugging can be found in the AVR 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 and XTAL1 pin during High-voltage Parallel Programming. For more details see 3.2.2 Highvoltage Parallel Programming. Figure 3-9. JTAG Connector 1 2 TCK GND TDO VCC TMS RST NC(VCC) NC(BS2) GND(XTAL1) TDI JTAG Note: AVR Butterfly User Guide 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. -19 4271C–AVR–04/05 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 Debugging” 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 Figure 3-7 for the pinout. If the JTAG are not in use, the four JTAG pins can be used as input for the ADC channels ADC[4:7]. See the ATmega169 datasheet for more information, available from www.atmel.com 3.4 LCD Display The LCD display on the AVR Butterfly is the same as used on the STK502 available from 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 display, 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 application note “AVR065: LCD Driver for the STK502 LCD”. Note: Touching the LCD-pins will affect the segments on the LCD. 3.5 Joystick -20 4271C–AVR–04/05 The AVR Butterfly has a miniature joystick for input from user. It operates in five directions, including centre-push. The common line of all directions is GND. This means that internal pull-up must be enabled on the ATmega169 to detect the input from the joystick. AVR Butterfly User Guide Figure 3-11. Joystick Schematic 3.6 Sensors The AVR Butterfly has two on-board sensors which makes it possible to measure both temperature and light. In addition is has a voltage-divider that is used to measure voltages from 0 to 5V. 3.6.1 Temperature Sensor The temperature sensor can be found at the back side of the AVR Butterfly. See Figure 3-12. AVR Butterfly User Guide -21 4271C–AVR–04/05 Figure 3-12. Temperature Sensor An NTC (Negative Temperature Coefficient)-thermistor is used to measure the temperature. An NTC-thermistor is characterised by the fact that when the temperature goes down the resistance goes up. Using a voltage divider and reading the voltage over the thermistor through the ADC-channels on the ATmega169, the temperature in can be calculated. Equation for calculating the temperature in Celsius is shown in Figure 3-13. Figure 3-13. Temperature Equation β Temperature = --------------------------------------------------------------------------- – Tzero ADC β -⎞ ⎛ ln ⎛ ------------------------------------⎞ + ------------⎝ ⎝ ( 1024 – ADC )⎠ Tamb⎠ β = 4250 ADC = Value in the ATmega169 ADC Data Register – ADCL and ADCH Tzero = 273°K Tamb = 298°K (273° + 25°) The temperature in Fahrenheit can be found from Figure 3-14 Figure 3-14. Fahrenheit VS Celsius F – 32 )⎞ ⎛ (-------------------- = C ⎝ 1.8 ⎠ The AVR Butterfly is capable of measuring the temperature from –10ºC/+14ºF to +60ºC/140ºC with an accuracy of ±1ºC. -22 4271C–AVR–04/05 AVR Butterfly User Guide 3.6.2 Light Sensor The light sensor is located at the front of the AVR Butterfly, over the LCD. See Figure 3-15. Figure 3-15. Light Sensor An LDR (Light Dependent Resistor) is used to measure the light. An LDR is characterised by the fact that when the light decreases the resistance goes up. Using a voltage divider and reading the voltage over the LDR through the ADC-channels on the ATmega169, 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 connected to the pins shown in Figure 3-16. Using a voltage divider and reading the voltage over the resistors through the ADC-channels on the ATmega169, the applied voltage can be calculated. The accuracy is about 0,1V. Figure 3-16. Voltage Readings Note: 3.7 Connect to PC AVR Butterfly User Guide Do not apply voltages above maximum 10V The AVR Butterfly has an on-board level-converter for the RS-232 interface. This means that no external hardware is required to reprogram the AVR Butterfly using the self programming feature in the ATmega169. Figure 3-17 shows how to connect a serial-cable to the AVR Butterfly. The integrated RS232 level converter operates down to 2.0V supply voltage. -23 4271C–AVR–04/05 Table 3-1.

USI AVR Butterfly USI Pin 1 (USCK/SCL) Pin 2 (DI/SDA) Pin 3 (DO) Pin 4 (GND) 3.9 External DataFlash An external dataflash is provided with the AVR Butterfly. This is the 4-megabit serial DataFlash from Atmel, type AT45DB041B. More information about the DataFlash can be 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 communicate with the ATmega169 on the AVR Butterfly, it can also be accessed externally through the ISP connector. Note: If the DataFlash is to be accessed externally, the ATmega169 on the AVR Butterfly must be set to disable its own SPI interface to avoid contention on the interface. Figure 3-19. DataFlash Figure 3-20. DataFlash Schematic AVR Butterfly User Guide -25 4271C–AVR–04/05 3.10 Piezo element A piezo element is used to be able to play sounds on the AVR Butterfly. The piezo is connected to PORTB5 on the ATmega169. And using the PWM, one can get the different frequencies required to play tunes. Figure 3-21. Piezo Element 3.11 Battery Model: CR2450 Nominal Voltage: 3.0 Volts Nominal Capacity: 550 mAh (@0.2 mA Discharge Current, +23ºC) Standard Discharge Current 0.2 mAh Maximum recommended current under continuous discharge: 3 mA Maximum recommended current under pulse discharge: 15 mA Note: DO NOT recharge, short-circuit, disassemble, deform, heat or place the battery near a direct flame.
