Post a copy of your sketch so I can run it and see what is happening.

Missing pixels in lines is a problem encountered with the new 1.6.12 IDE,  I have updated the ILI9341 library on Github to correct this.

I'm really sorry for the delay, didn't get any forum notifications.

I've updated the library and now it works great! Thank you so much for your support!

I am a beginner
And look for the error.
For many days

Thanks for any help

Trying to think of things which could slow down a lot of writes to an LCD, I see that you have quite a few pins in use, but ?no? mention of pullup resistors.  Does the screen or adafruit recommend anything ? 
Your code looks as though it is going to presume 30k pullup built in, which might require comms to go slower than their best or be less reliable than ideal, especially if you have more than 6 inches of cabling from microcontroller to display.  Various opinions abound about adding external pullup resistors from a digital pin to arduino Vcc, but I found 10kOhm or 3.3kOhm more likely to work than none at all and necessary when using a few feet of cables.

Hello,
Was a copy error.
There was wrong data in the file.
For whatever reason.
Thanks

Hello,
hm work only with Arduino Duo
i have Arduino Due  ;o(
But it is fine
thx

As you are a beginner I would start by creating a simpler sketch! For example just draw a line though the centre of the screen at an angle that is output by the sensor.  You will need to store the end coordinates of the last drawn line so you can erase it by over-writing with background before drawing the new line.

Hi there ...
Does anyone here?
I want to run this code for horizon indicator, any other updates?
Hey guys, is this topic active?

Hello Bodmer:

I have been using your TFT eSPI library with a M5stack ESP32 320x240. Works quite well ! I was wondering - why not make a artificial horizon indicator using the sprites. The pitch scale and sky+earth image would be replotted as a sprite with the wings symbol static (along with other features). What do you think ?

@DrWino

I did try this and it works. I will tidy up the sketch and include it as an example. I also created a simple animated compass with moving needle and dial which I might add.

Very good. Can you send me the example ? Does not matter if it is not too finished - it will a good exercise to figure out how you did this ! Thanks.

Hello BOdmer! I am using the ILI9341_due Library and the same solved problem on  post #46 appears again. Can you help me? Som missed pixels in the border of moving Indicator.

Tahnks!
