LiquidCrystal is starting up properly, at last!

As any arduino developer that worked with LCD displays would now the LCD initialization is a pain in the ass.

The LiquidCrystal library that came with the arduino files until arduino-16 did not propperly initialize all liquid crystal displays.

The supplied LiquidCrystal library with arduino-17 which solved those issues did not work for us (I’ll leave the technical details out, just believe me on that).

We knew the root of the problem and we had some ideas on how to solve that but it was not until I found this magnific post from Ed that I did not get it to work.

This post is just to say thanks. Kudos. I owe you one and all that.

Yeah, that FLOSS thing is quite great.


nice IDE, what do you do tonight?

The batteries work and the system is almost ready to be embedded in some kind of toy.

Here you can see the lens case hanging from our wonderful IDE cable.

We choose IDE because it’s quite cheep and it’s also great looking, all futuristic looking weapons should have IDE cable’s hanging from them!

We recently bought two sets of two 3.7v batteries at dealextreme.

We’ve had a surprise when we discovered the size of the batteries. Here’s a photo of them.

We where expecting regular sized AA batteries. I know, it’s our fault, nothing said it should be that way.

Anyway, they are charging and we expect that they will work great.

wrapped up to go

All our testing hardwar fits inside this box.

I’ve had “the box” all of august and now I am packing it and delivering to the other half of the team.

Hopefully next time we have pictures of the boards they will fit in a much smaller box.

Back from the summer holidays

We’ve been on holidays but we haven’t left the project completely behind.

Between July and August we’ve come frome here:

To here:

We plan on having the alpha prototypes within a month!
