  • Page 5: Introduction

    Section 1 Introduction The STK502 board is a top module designed to add ATmega169 support to the STK500 development board from Atmel Corporation. STK502 includes connectors and hardware allowing full utilization of the new features of the ATmega169. The Zero Insertion Force (ZIF) socket makes it easy to use of TQFP packages for prototyping.

  • Page 7: Using The Stk502 Top Module

    This section describes in detail how the STK502 is used with the STK500. Connect STK502 to the STK500 expansion header 0 and 1. It is important that the top module is connected in the correct orientation as shown in Figure 2-1. EXPAND0 written on the STK502 top module should match EXPAND0 written beside the expansion header on the STK500 board.

    2528A–AVR–11/02 Figure 2-2. Pin1 on ZIF Socket and TQFP Footprint Caution: Do not mount an ATmega169 on the STK502 at the same time as an AVR is mounted on the STK500 board. Neither of the devices will work as intended.

    RESET-signal that comes from the STK500 board. Please note that it is not directly con- nected to the ZIF socket or the TQFP footprint on the STK502. This because the RESET-signal on the STK500 has an pull-up resistor to VCCT which will interfere with PG5 when used as an ordinary I/O-pin.

  • Page 10: Programming The Atmega169

    To program the ATmega169 using ISP Programming mode, connect the 6-wire cable between the ISP6PIN connector on the STK500 board and the ISP connector on the STK502 board as shown in Figure 2-6. The device can be programmed using the Serial Programming mode in the AVR Studio4 STK500 software.

  • Page 11: High-Voltage Programming

    To program the ATmega169 using High-voltage (Parallel) Programming, connect the PROGCTRL to PORTD and PROGDATA to PORTB on the STK500 as shown in Figure 2-7. Make sure that the TOSC-switch is placed in the XTAL position. See Section 2.6, “TOSC Switch”.

    JTAG Connector 2528A–AVR–11/02 Figure 2-8 shows how to connect the JTAG ICE probe on the STK502 board. Figure 2-8. Connecting JTAG ICE to the STK502 The JTAG connector is used for the ATmega169 built-in JTAG interface. The pin out of the connector is shown in Figure 2-9 and is compliant with the pin out of the JTAG ICE available from Atmel.

    ATmega169”. The header next to it, labelled “STK502 LCD pins” holds all the segments-pins for the LCD-display on the STK502. By using the 34-lead cable that comes with the STK502-kit, the two pin-headers can be connected, allowing the ATmega169 to control the LCD-display. See Figure 2-10.
  • Page 14 Seg. M169 This hardware configuration will give a certain bit-mapping between the bits in the ATmega169 LCDDRx Register and the segments on the STK502 LCD. See Section 4.1 “STK502 LCD Bit Mappings” With the header J300 labelled “19 24” one can connect LCD-pin 24 (which is default unconnected) to LCD-pin 19 by the use of a jumper.
  • Page 15 Make sure the display is compatible with the electrical characteristics on the ATmega169. 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: The LCD-display on the STK502 can be ordered separately from ACTE Norway (www.acte.no).

  • Page 16: Tosc Switch

    On the ATmega169 the TOSC1 and TOSC2 lines are shared with XTAL1 and XTAL2. The TOSC switch selects whether the 32 kHz crystal on the STK502, or the XT1/XT2 signals from STK500 should be connected to these pins on the device.

  • Page 17: Sensor

    “AVR064: STK502 – A Temperature Monitoring System with LCD Output” describes the details of the application. Two switches on the STK502 are used to connect the sensor to the ADC-channels on the ATmega169 as shown in Figure 2-17.
