Speaking digital thermometer demo

[Harty123]

Hi,

I'm finished my work on a digital thermometer based on the Uzebox platform with an digital I2C temperature sensor LM75. Here is a first preview of my work:



You will find detailed information about this thermometer in the wiki.

It is possible to connect a LM75 temperature sensor to the Uzebox hardware (SDA = PD5, SCL = PD3, address = 0). In this case the demo will measure and show the temperature of this sensor in realtime. Without a sensor the program runs in so called DEMO MODE with simulated temperature values.

Cool, that's a nifty idea Harty! I reckon there should be more hardware things made with the Uzebox. I'll try it for sure and get one of the sensor on mu next digikey order.

I second all of that.

The display is very cool; that thermometer looks gorgeous on my avcore and the digital display looks really cool in uzem! Can't wait to test it with the LM75.

Nice job!

Hi,

@Uze and Hardlyunique

many Thanks... For the dotmatrix style I find inspiration by the multi function display in my VW Passat... The big advantage of this style is that I need only 2 tiles for it.

I've realized, that in the Uzebox schematic PD2 is in use for the power switch (? - no idea how this works) but PD5 is unused and also available on the expansion slot. So in the further development I will change the SDA signal to PD5.

Hi Harty,

I'm interested in your inclusion of the UzeAmp into a different program. Does it also support sound effects?

If you can mix sound effects and the playing of a wave file via UzeAmp, I would be have a very big hurdle of my next game project cleared out.

I would really like to do a Intelevision Space Spartans remake, but the voice/sound effects have to work before I really grind on it.

Hi,

I've changed the code to PD5 for SDA see above. About the LM75: this chip is often used in PC mainboards as temperature sensor. If you have an old mainboard check it - perhaps you can recycle the sensor.

Space Spartans - great idea for an Uzebox game!

Hm at the moment I do some experiments with the converting of sound files in the right format - with good results. Also I tried to understand the source code of Uzeamp. It looks like that it is possible to mix sound effects with the playing of a wave file. But I don't need this feature for my application. I will inform you about the results of my experiments in the next days...

Hi,

the first version of the speaking thermometer is finished now. See above.

Voice!! It works flawlessly as usual...and in 2 language as a bonus. Though all those little wav files should ideally be bundled into one or two. I was refactoring the Uzamp code this weekend and a new feature could be the ability to play the wav file from an arbitray point and for a certain lenght.

Nice work Harty!

Yes thats a good idea for future versions of Uzetherm to put all wav files of a language in one file .... I can save a lot of RAM with this feature.

P.S. If you want to create a news item, pls wait until I've added the source code in the wiki!

That's really inventive, Harty! I like how you seem to consider the Uzebox more of an experimental prototype board rather than a game console
