Getting Started

This section describes how to connect the STK504 onto the STK500, how to

place the AVR in the ZIF socket and connect cables to different peripherals.

Hardware overview

The STK504 is a flexible platform for debugging the 100-pin LCD AVRs. The

card offers lots of connectors so you can connect to your own hardware, or you

can use it as it is.

ZIF socket:

This is the place to put your AVR sample. See Placing the AVR in the ZIF

socket chapter for more details.

LCD PINS:

This connector is wired to the on-board LCD. It is usually connected to

the AVR SEGMENT PINS connector. Consult the LCD section for more

information.

AVR SEGMENT PINS:

This connector is wired to the LCD pins on the AVR. It is usually

connected to the LCD PINS connector. If you want to connect your own

LCD, then use this connector. Consult the LCD section for more

information.

Port connectors:

The AVR's PORTE, PORTF, PORTG, PORTH and PORTJ are available

on five connectors, each one marked with the port name. Each of the

connectors has the port signals and a target voltage and ground pin. See

Appendix A for description and pinout.

Clock switch:

This switch select what clock course is routed to the XTAL/TOSC pins on

the AVR. The switch has three states, X = clock signal from STK500, LF

= onboard 32kHz crystal and HF is on-board crystal socket. See Clock
