arduino-pico VS VINS-Fusion

I managed to get the Arduino IDE to work great with my Pi Pico's using earlephilhower/arduino-pico and TinyUSB in the USB stack. I can code for MIDi and do all kinds of neat stuff... But...

I am trying to build a data logger. Currently my hardware is a Raspberry Pi Pico W, a SHT41 (https://www.adafruit.com/product/5776), and a small breadboard. Software is Arduino IDE, arduino-pico (https://github.com/earlephilhower/arduino-pico), and Adafruit_SHT4X library (https://github.com/adafruit/Adafruit_SHT4X).

The standard Pico w SDK has examples for Bluetooth classic, serial connection, mouse control, keyboard control etc... Everything you need can be found HERE

If you want more guidance, you could use the Arduino framework https://github.com/earlephilhower/arduino-pico

If you are using the earlephilhower implementation of the Arduino Core for Pico, wifi is documented here: wifi docs

rp2040 is really powerful its not a conventional "desktop" raspberry pi, its a microcontroller similar to stm32 or the avr boards that the arduino uses. https://github.com/earlephilhower/arduino-pico for arduino support.

Do you want to do serial communications along with USB HID (keyboard)? Sure, you can do that with TinyUSB. I've done it with the arduino-pico core: https://github.com/earlephilhower/arduino-pico

No, it is not necessary in that case to add a wheel encoder. You can use visual-inertial odometry. You could use e.g.: https://github.com/HKUST-Aerial-Robotics/VINS-Fusion.

Bookmarked.No later than yesterday I was investigating the feasability of doing visual and inertial simultaneous location and mapping using this SLAM library https://github.com/HKUST-Aerial-Robotics/VINS-Fusion.

Also this is a great starting point, it contains a list of the most popular algorithms, if I remember correctly VINS-Fusion was the most promising one. This kind of algorithms are primarily designed for drone path tracking, I haven't tested any of them so I don't know how well they might work for VR applications.
