ImageDisplay Service


ImageDisplay is usefull to open local or remote pictures, and render result to screen...

Fun example, create an ImageDisplay service and one of the Search services - attach them and ask for a picture of something. It should appear (fullscreen if you want).

You can move the image around with by holding down the left mouse button, and close it using the right mouse button.

Example for develop:

Setting up the Raspberry Pi. Update for Buster and Bullseye

Ray.Edgley's picture
We will need a MicroSD card to hold the Operating System. (OS) I suggest a 32GB class 3, but a class 1 will work.
The last version released was Buster, the most recent is Bullseye in both 32 bit and 64 bit.
In any case you will need to use a flash program to copy it to the MicroSD card.
You can use the Raspberry Pi Imager or another imager, 
I used BalenaEtcher
Using either program flash your chosen OS to the MicroSD Card.

4xADS1115's (giving 16 Analog to Digital channels)

Gareth's picture

Here are some details of how I cobbled up a 16 channel ADC rig for use with MRL's Ads1115 service

As you can see above the i2c SDA/SLA lines require 10k resistors as pull up loads.

The trick to keeping it compact is to the stack and common through the GND,SDA,SCL,VCC pins (see below)

Matrix X,Y plotting Numeric's with the Neopixel service

Plotting character sets to the Neo_Pixel Service.

Numbers can be fitted into a 4x5 (with a little flare) matrix, so here is a simple set based in Python to get you going.

Worthy of note is Python has a triple """ option for text declaration, which means you can include new lines in the text input, so I was able to separate the character bitmaps to some degree.

Usage :-

Matrix X,Y plotting with the Neopixel service

Gareth's picture

Python code to enable x,y plotting from the neopixel service, an inviting rabbit hole.

Many Matrix displays have a serpentine LED pattern. This means that odd and even columns are reversed.

Information about openCV

Gule's picture

Can anyone show me where I can find information about how openCV is integrated in MRL?

I try to get openCV to run on Ubuntu 20.4. With manticore version when capturing a frame webgui freezes, no interaction is possible. With nixie, there is an error message "could not get valid frame".

Which version of the openCV libraries has to be  installed in the system? What python scripts for openCV come with the installation of MRL and where can I find them?

Thanks for any support
