You can get better resolution by using the serial port Tx line in master SPI mode 0, see this YouTube video for an example, and a link to download the code in the video description.

I was searching for a project like this.

I have a 3 inch lcd from my car rear view camera. It has 2 analog video inputs. Can I use this display in arduino or nodemcu project. Don’t want to spend in purchasing a i2c display.

For anyone building this, I used the schematic listed in this article as well as the listed TVOutBeta1.zip libraries. In the TVout folder in the attached libraries is an example folder. I used the example “DemoNTSC” and copied the files into a folder under arduino called “DemoNTSC” and I renamed the DemoNTSC.pde file to DemoNTSC.ino. I uploaded that to an arduino nano using pin 7 for video and pin 9 for sync and the example worked on the first try. I am using this in my Pace Arrow motor home to display information on the monitor I have for my backup camera which has 2 AV inputs. AV2 is used for the backup camera, but AV1 did nothing other than display “No Signal” on a blue screen when driving. Now I have it displaying the status of my TV antenna mast whether it is up or down. I am planning to incorporate other things like the status of my electric step for the entry door (in or extended), and possibly my leveling jack status once I get those fixed. Here is a video showing what I have so far. https://www.youtube.com/watch?v=6Y70Jyy1D04 To do the Pace Arrow logo I used a image to C hex converter from this website, which worked perfectly. https://www.digole.com/tools/PicturetoC_Hex_converter.php

Many thanks for this post.

Looks like you haven’t included the actual font you’re calling on. Could this be the issue?

So it does! I can’t find the original file, must be on another computer. Will keep looking.

The source code that is shown ends prematurely.

Giles –

Thank you for this post. It is very clever. I love the simplicity of it.
