Introduction
This document explains the operation of the STK511 – an AVR
®
-based UHF Radio Evaluation Kit. The
STK511 Starter Kit was developed as a tool for evaluating Atmel's receivers (ATA5743, ATA5744,
ATA5760 and ATA5761) and transmitters (T5750, T5753 and T5754). Although most Atmel receivers
require programming of configuration registers via a bi-directional, one-wire interface, this kit provides
register programming in an easy to use way for the customer to quickly evaluate an AVR-based UHF
Radio system. Included in this kit is software to evaluate both ASK and FSK modulated radio systems
across the RF spectrum of 315 MHz to 915 MHz and complete reference designs for receivers and
transmitters. While above mentioned ICs are supported by this kit, pre-configured kits are only available
for 868 MHz (using ATA5760 and T5750) and 915 MHz (with ATA5761 and T5750).
In addition to providing a quick, one-step, programming tool for configuring Atmel RF receivers, the
Receiver Interface Board of the STK511 Starter Kit doubles as an expansion card for the STK500. This
allows the user to develop software for receiver applications using any of the AVR microcontrollers sup-
ported by the STK500. The STK511 Starter Kit, when combined with the STK500, enables extremely
quick prototype development for customers interested in Atmel's UHF radio design solutions.
