Hi Jph,

Thanks.

I will have a look on the doc, but these reduction is more mechanical : motor / propeller.

I will check and let you know.

@Keith Baxter

You're my hero !

I've made some tests and the needle is ok now ! I will finish this instrument and post the result.

Thanks again !

@Ralph

If i double the size of the picture, it's not good at all.
Sorry for the misunderstanding.


@Keith Baxter

I'm missing something.

Here are the png files:





thanks for your help and explanations !

Jack,

This a PA28 Thielert.

CT means Coolant Temp
GT means "Température du réducteur" (I'm looking for the english translation)

Fuel Temp (left and right) does not exist either. I'm using ambient temp and add a random number .

I've just tried to use this command line, with some values for X and Y. rotate(img_needle,i, 256, 256, 0) Still not good. What should be the size and position of the needle picture ? Big doubt ! https://i.imgur.com/hHDIsZW.png Here's a link to my instrument (is it the good way to publish it here ?) ...

Hi,

Almost finished fo these ones :



CT & GT values does not exist; so i will find a rule.

Again, thanks for your great help.

@JackZ

I'm sorry, i missed your last post !

I'm working on this gauge again, and its' almost good.

I can't figure out how to modify the white needle axis of rotation (it should be the same as the purple lines)



I've tried many thing, without success.

I agree !

Keith, thank you !

Based on your code it's working as i wanted !

As you can see, leds are off and are visible. And 6 green leds are on.



Thank you again for your help and your time.

I will try and let you know !
