Mode- 0

(1) : ARINC 429 Data reception using on-chip RAM

The user must provide valid ARINC 429 data on any/all of the ARINC receivers (J2) to operate in this

mode. The HI-3200 is configured to receive and store valid ARINC 429 words in RAM. The program will

read the received data words using the SPI bus and display them on the console.

The output on the console will be similar to:

(2): ARINC 429 Data reception using on-chip filters and FIFOs

This example demonstrates how received data (provided by the user) can be filtered and stored in FIFOs.

This will allow the users to store up 32 received and valid ARINC 429 words.

The output on the console will be similar to:
