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.

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.

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.

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.
