I started a list of sensor development kits, on Github this time.
Pysense: hardware setup in a virtual machine
I had to help someone starting a project which includes, among others, a Pysense board.
The development environment was Linux Mint 18.3, running in a VirtualBox virtual machine (VirtualBox version 5.2.26). The host system was a MacBook Pro running macOS Mojave.
One difficulty that the user may face with this environment relates to the USB device redirection. When the Pysense is switched to bootloader mode, for firmware upgrade, it stays in this mode less than 7 seconds, which is not long enough to configure VirtualBox.Continue reading “Pysense: hardware setup in a virtual machine”
Some programmable wireless ICs and modules
Some integrated circuits or modules providing wireless connectivity (Wi-Fi, Bluetooth, Public Land Mobile Radio aka 2G/3G/4G, etc.) or satellite positioning, can host some customer code. Below, some of them.
Note (on the 29-Mar-2023): I haven’t been updating this post for almost a year now. It may contain some old references that are no more valid. I will review it some time soon. Continue reading “Some programmable wireless ICs and modules”
IoT device development kits
Here is a list of various low cost programmable boards or kits, with some (wireless) connectivity. This list is maintained on a best effort basis only.
