Introduction
The Holt ADK-35850 Evaluation board demonstrates the features of Holt’s ARINC 429 HI-35850. The HI-
35850 includes one complete ARINC 429 receiver and transmitter with line driver. The HI-35850 is a new
version of the HI-3585 but has a much higher 12MHz SPI frequency. The example board set includes an
ARM Cortex M3 base board and the HI-35850 plug-in daughter card. The kit uses IAR as the development
IDE and an integrated USB debugger port is included on the base board so no other USB programming
adapters are needed.
This guide describes how to set up and run the pre-programmed demos. Additional support material and
all required project software are found in the included Holt USB memory stick. A version of the
demonstration software is pre-programmed into the microcontroller flash which makes the board
operational right out of the box without installing or running the provided software development tools. A
later section in this guide provides instructions how to install IAR and load the demo program. Installing
IAR is not required to run the demos since this program is pre-programmed in the MCU flash memory.
