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 https://www.raspberrypi.com/software/ or another imager, 
I used BalenaEtcher https://www.balena.io/etcher/
Using either program flash your chosen OS to the MicroSD Card.

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

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.

NeoPixel matrix

I think perhaps the individual pixels for the UI might be a bit too clunky ...
but its nice to know the update to MrlComm can handle 8x32 matrix.
Needs to have a scroll text function ... hmmm
