No we are also doing ground based astronomial telescopes. 

 

This being one of them http://j-pas.org/

@Max: Now there is something I agree with you on and that is the Arduino Workshop.

I like it because it has a lolt more than just Arduino.

I have it in e-book form, so it can reside on my bench laptop when I am forging the little chips to my will.

@Adam: ...they may find there way into one of our telescopes...

Are you talking about a telescope intended for deployment in space?

@Crusty @Steve: As it is an Atmel chip are you using Pin Change interrupts?

Thinking about it, there are de-bounce functions in the Arduino library. Steve, do you have the Arduino Cookbook or the Arduino Workshop? (Both are recommended, but if you only get one, make it the Workshop). They cover this sort of thing.

Max of course you are invited, it is going to be the party. 

These neo pixels are pretty amazing - they may find there way into one of our telescopes ;)

Hi Steve:

It sounds like you are going through quite a steep learning curve.

But the project and what you are producing look worth the effort.

Rotary encoders can be a pig to debounce, I usually do this in software, its almost a trade against filtering the input and missing clicks on the swich position, which can be annoying, especially with counting up and down.

I have not tried it yet but, I think a timer reset after each interrupt from each bounce and read the state of input pins when the timer is able to time out. This should take out the problem of switches getting worse on bounce as they get older.

As it is an Atmel chip are you using Pin Change interrupts?

Max can give you my contact info in England, if you want to discuss Atmel chips and software offline.

I think I am better at Micro's than FPGA's

Having beeen using the neo pixels to demonstrate to people how to use the Zynq I have a few ideas of how to use these pixels on my new house and garden especially

@Antedeluvian @Steve: And altough you are commited to the Arduino, I should mention that the PSoC3/4/5 has it as a built in fuction.

I seem to recall that there is also a Neo-Pixel library available for the PSoC devices, but I don't know where you go to find it.

Hierarchical Menu Structure

A standard 16x2 LCD display with white text on a blue background, ordered through Amazon UK

At the outset this eeems like a simple thing to do, but take care. Changes in approach often may mean rewriting your driver from scratch. After working with a customer who chagend their mind frequently I created an approach to allow a systematic method to create hierarchical menus and how to display dynamic data within that.


I wrote it up in a Circuit Cellar article "hierarchical menus in embedded systems" published in issue #160, November 2003. Circuit Cellar's business model requires you to pay a small amount, and for articles of that age you have to download the whole magazine. Let just say that the code was written for the Rabbit micro, but is all in C and should be easily portable.
