Hello there,
I have a litte project in my but I would like to be sure that it is feasible before going any futher…
My idea is to build a dashboard display powered by a battery, this dashboard needs to get datas from internet feeds (via a wifi network)
As we talk about battery powered solution, I immediately thought of the e-ink screen which consumes nothing (when you don’t modify the display) and which suits my needs because I don’t need to refresh the screen often.
I made some tests with a rpi zero and an Inky pHAT, the big problem comes from the consumption of the rpi zero… I have a python script that works when I need it for the display, but the static consumption of the pi drains the battery in a few hours and this is not acceptable for this projet…
So I thought I had to find an other platform that consumes less or that allows you to go into deep sleep states which the pi is not able to do…
So I will need to port my project (coded at the moment in python) on a micro-controller and while doing some research on the net, I came across Circuitpython… and the Feather S2 which can suits my needs…
So here are my questions:
- Does a python code made for a rpi zero, needs a lots of modification to be able to run on a CircuitPython platform ?
- Is it possible to run a code on the feather S2 to drive the inky pHat ?
- Do you know if this code is availabe somewhere ?
- If not do you think it’s possible to fork the inky pimoroni library (https://github.com/pimoroni/inky) to make it run on a circuitpython compatible platform ? Looking at the code on github, I realize that the lib just sends commands on a SPI link which a CircuitPython platform should be able to do…
- What is the voltage needed by the inky, could it works with 3.3V ?
I know i’ve alot of questions…
Many thanks for helping me going forward on the project
Cheers
