Background
I have installed Venus OS version 2.42 on a Raspberry pi 3b+ without any significant problem. I have the 7" touch screen working including dimming and screen blank timeout. All this following the instruction in the video https://www.youtube.com/watch?v=I39uEwnrXWc from Himmelberger Bus. So I know how to use nano and how to install overlays, edit the config.txt file, and generally know my way round Linux / Ubuntu etc.. I even have a £15 GPS USB device working and logging location to the VRM. I am hoping to connect to my Victron BMV 700, MPPT and Multi compact when I can, but they are on our boat in the marina right now so I won't be doing that till later in the season.
I have a PI HAT (custard Pi 3a) with an MCP3208 on and have installed the MCP3208 overlay and edited the config.txt file.
Question
I am stuck at this stage:
- I downloaded the compiled image for the Venus GX, ripped out the /opt/victronenergy/dbus-adc directory from the image with 7-zip, copied the directory to the Raspberry Pi.
Exactly what is the "compiled image of Venus GX" I need ?
And the steps needed to extract the directory?
(Sorry that's two questions on one post )
What I have tried
I have tried everything with many of the images here (Raspberry, BeagleBone and ccgx ) https://updates.victronenergy.com/feeds/venus/release/images
I have opened them with 7-zip blown images to SD (using BalenaEtcher) and then looked on the SD using MAC, Windows and Linux I can't seem to find the bus-adc directory I need anywhere.
I have a MacBook pro with a windows partition to answers for either MAC or Windows will be fine.
Please help - thanks
PS
would it hurt for the dbus-adc directory to be included in future raspberry pi images, I presume they would publish nothing to the dbus u unless the rest of the interface and drivers were present?
I'm and active user electronic engineer and programmer so I will be happy to contribute in future what I have learnt and managed to do with the analogue inputs - my plan is to develop some custom circuity with FETs to interface the tank level voltages I have on the boat to the input range of the Custard Pi 3a HAT. Also considering onboard temperature and humidity for monitoring over winter.
