4271C–AVR–04/05 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 AVR Butterfly. 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 AVR Butterfly on the AVR Butterfly can be programmed using SPI, High-voltage Parallel Programming 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.

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.

-16 AVR Butterfly User Guide

4271C–AVR–04/05 3.2.2 High-voltage Parallel It is possible to program the ATmega169 through the High-voltage Parallel Program- Programming ming 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 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.

4271C–AVR–04/05 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-voltage 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 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 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 and XTAL1 pin during High-voltage Parallel Programming. For more details see 3.2.2 High- voltage Parallel Programming.

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.

AVR Butterfly User Guide -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 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 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 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.

-20 AVR Butterfly User Guide

4271C–AVR–04/05 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.

The AVR Butterfly is capable of measuring the temperature from –10ºC/+14ºF to +60ºC/140ºC with an accuracy of ±1ºC.

-22 AVR Butterfly User Guide

4271C–AVR–04/05 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: 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 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 sup- ply voltage.

3.9 External An external dataflash is provided with the AVR Butterfly. This is the 4-megabit serial DataFlash 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 commu- nicate 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 But- terfly must be set to disable its own SPI interface to avoid contention on the interface.
