how to inteface HI-8476 ic in stm32

Yugenthar · ‎2023-02-21

Hello every one .Im yugenthar

I need your help

Anyone Know th arinc-429 protoacl

Then how to implement the stm32F

Any boady know this concept Please give the sollution

Yes bro but this board is not in my hand .Actual this Board is using in DIP Switch but how to send the data frame in using stm32 or other controller the how to veiw the output .Using this board

This is my FRAME:Arinc-429

EXAMPLE:

STAR-00,

LABEL-299(octal)

SDI-01

SSM-11

DATA-4095 ADCvalue

PARITY-01

Then One Quation how to buy this Demo kit Board

Your are using this board then give the price rate bro.

Please give any sofware simulator for view purpose

This is Microcontroller output.using Docklight

But this working only Stm32 microcontroller not in ARINC -429 HI-8476 board.

AScha.3 · ‎2023-02-22

Sorry to say - but i dont have this board and i dont know much about the ->ARINC_429 for aircraft .

https://en.wikipedia.org/wiki/ARINC_429

what you wanna do then ?

If you feel a post has answered your question, please click "Accept as Solution".

Yugenthar · ‎2023-02-22

Actually one doubt its possible to implement the stm32 or any other microcontroller.

If you any idea this protocal Please give me

Yugenthar · ‎2023-02-22

So I am reading Few R&D Paper mostlyof the paper are using FPGA concept in arinc 429 protocal are implementing so why FPGA are using in protocal.

Tesla DeLorean · ‎2023-02-22

Probably because it's a bit of a niche and not something done on general purpose commercial MCU

The are ARINC 429 receivers with an SPI interface for connectivity to an MCU

Tips, Buy me a coffee, or three.. PayPal Venmo
Up vote any posts that you find helpful, it shows what's working..

Yugenthar · ‎2023-02-22

Any particular module are available in low price using arinc -429 protocal

please give the link .then any know the HI-8475 ic..I have one small doubt why using DIP Switch use control label .how to send my frame to this Board

AScha.3 · ‎2023-02-22

first line in description:

>The HI-8475 is an ARINC 429 Receiver designed specifically for use without a microprocessor.<

so this board is for testing something without needing any cpu.

but want to use a cpu - right? and what you want make then with arinc in airplane ?

here a lib , in rust:

https://github.com/samcrow/arinc_429.rs

and in python

https://github.com/aeroneous/PyARINC429

and even for a raspberry:
