virtual usb raspberry pi

[xjust]

This is just a tip.. maybe somebody is tired of cables when changing code to arduino and might find this usefull.

Current setup: raspberry pi0w connected to arduino. Camera can also be attached to it. This draws way less energy from the battery than a rpi 3b,4.

Using https://www.virtualhere.com/usb_server_software , we can map the usb connection to arduino as a virtual com port on the windows main pc, to debug/recompile arduino code.

Maybe it can work with Pi zero.But the issue to update the Due firmware without wire is :
The due put the output 4 to low and poweroff all the PCB1.3 during all the downloading of firmware and if the Pi is powered by PCB1.3 update fail !!!!!!.

I use the piZero on RL1000 for 2 or 3 months but without really a good change in battery life and very poor performance ,so i am back to Pi3B+.
The only advantage is that the wiring is very simple.

Great! And another tip : Read-only File System with Overlay - Allows you to power-down the Raspberry without correctly shutting down. Idea is to activate Read-only with Overlay when the Raspberry basic files are not changed, and to disable it when changing basic files on it...

First, upgrade your packages:

sudo apt update
sudo apt full-upgrade
sudo reboot

You can then configure a read-only file system by :
going to Preferences–>Raspberry Pi Configuration–>Performance–>Overlay File System–Configure…

or: sudo raspi-config, Advanced->Overlay File System

To avoid any power loss when flashing from the PI, how about powering the rasp PI through a very small UPS like this one here: https://www.aliexpress.com/item/33052022274.html?spm=a2g0s.9042311.0.0.27424c4dCIaJjf (5v version)

I have one powering another PI and its working really well

Maybe i can test this evening with the mower in the charging station
