Section 3Using 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 theAVR Butterfly

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

and the JTAG interface.

3.2.1 In-SystemProgramming


16/42


4271CAVR04/05

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 on

the 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 in

a 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 3-3fo

the pinout of the ISP Connector.

Figure 3-3. ISP Connector, J403

Notes: 1. More information about the STK500 can be found in the STK500 UserGuide, which is available at the Atmel web site, www.atmel.com. SeeSTK500 User Guide for information on how to use the STK500 front-endsoftware 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 both

SPI 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.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 andpin 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 onthe AVR Butterfly.


18/42


4271CAVR04/05

Figure 3-6. PORTB and PORTD

See the Schematic and the Assembly Drawing in the 7 Complete Schematicsfor furthe

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 flicker

ing on the LCD, this because PORTB and PORTD are connected to theses modules.

Figure 3-7shows 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 Programmingmode, the JTAG interface will not work, neither will the external crystal, causingthe 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 UserGuide for information on how to use the STK500 front-end software in High-voltage Programming mode.

3.3 JTAG Figure 3-8shows 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 3-9and 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 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 andXTAL1 pin during High-voltage Parallel Programming. For more details see 3.2.2 Highvoltage Parallel Programming.

Figure 3-9. JTAG Connector

Note: It is highly recommended to apply external power (3,1 4,5V), when using theJTAG to save the battery. See Figure 3-10for how to connect external power.

Make sure to disable the OCD-fuse after a debugging session, due to powerconsumption. The OCD-fuse will be disabled if pressing on the Stop Debug-ging button in AvrStudio4, beforedisconnecting the JTAG ICE probe from theAVR Butterfly.

Figure 3-10. External Power

External power can be applied at pin 9 and 10 at both PORTB and PORTD, see Figure3-7for 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.comfor 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 noteAVR064: 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 thainternal pull-up must be enabled on the ATmega169 to detect the input from the joystick.

4271CAVR04/0

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.


22/42


4271CAVR04/05

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 goesdown 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 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 Figure

3-15.

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 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 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 3-17shows how to connect a serial-cableto the AVR Butterfly. The integrated RS232 level converter operates down to 2.0V sup-

ply voltage.

3.9 ExternalDataFlash

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 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 theinterface.
