I’ll start with an apology – I’ve been working on prototyping for this for over a week, And I’ve never too a video or a photo of the prototype working on the breadboard. So this post would be somewhat less illustrated then I would have wanted. sorry 🙁
I’ve decided to take the Indexer design concept and use the Shift register chip’s ability to be chained as a way to drive the Cation panel.
F-16 caution panel is made up of 4 rows of 8 lamps – classic for 8bit shift register, I just need to chain 4 of them and presto – the entire caution panel on 3 pins using SPI (CS, SCK and MOSI – where SCK and MOSI are shared among all the other devices anyway).
We’ll start by looking at the Caution panel structure itself.

Well After working on the thing for two months, I’ve got a pretty good concept on what I want to achieve.
I started with DED and grew from there.
The first obvious “victim” was the FFI, as it’s “right there”.
followed by the Indexers (again, “they are just there”).
then I just got greedy 🙂
PFL was next to be added – because “it’s basically just another DED”, closly followed by the caution panel “it’s right next to the PFL, and the code is just a bumped up Indexer”
and then I completely lost it..
and glareshield lights and TWP lights were also included on the roadmap and also the CMDS display – because I can.
But I’m pretty sure the Arduino cannot handle all of this – at least the base would be set for floks that would prefer having TWP over caution panel or CMDS over DED/PFL.
but connecting everything is not as trivial, especially in the cockpit environment – and bread board is out of the question of course.. cables are too fiddly.
So I’ve started thinking about a PCB design to accommodate all this and make it somewhat user friendly to assemble – but still maintain some flexibility.
So that would be covered in this post.
