AVR USB STK development board Users Manual Petes ee All boards produced by Olimex are ROHS compliant Rev A July 2008 Copyright c 2008 OLIMEX Ltd All rights reserved INTRODUCTION AVR USB STK is easy to use development board for the new AT9OUSB162 microcontroller With AT9OUSB162 is very easy to develop USB functionality to your next device as Atmel provide free open source HID mouse keyboard CDC USB to RS232 code and on top of this AT90USB162 cost is same ATMegalo so what you are waiting for AVR USB STK board allow all USB features of AT90USB162 to be explored The board have USB connector Joystick RS232 SD MMC card Audio output ICSP connector and extension connector AT9OUSB162 come from Atmel pre programmed with bootloader which allow code to be programmed inside the chip without any external programmer just download the FLIP software from Atmel web site and load your HEX code inside 90058 162 To enter the bootloader mode you should press and hold HWB button then press and release RST button If you prefer to use ICSP programmer note that only AVR DRAGON and AVR ISP MK2 is supporting 90 5 162 as these are pretty new devices probably AVR Dude will add support later but for the moment you can t use AVR PG1 or AVR PG2 for ICSP programming another bad news is that AT9O0OUSB162 supports only debug Wire not JTAG so to debug it you should have the expensive AT JTAGICE MK2 or AVR DRAGON BOA
