Pretty crazy project for my undergraduate thesis, microcontroller program fully written in typescript. Should have been written in C++ atleast, but oh well.

Uploaded to source control to persist the project.

It's pretty much a simple communication system built to handle communication between multiple node using LoRa while also preventing collision. Very naive implementation using custom ZeroMQ Request/Reply. Ideally, should implement a full-blown CSMA/CR (Carrier Sense Multiple Access with Collision Resolution), but that protocol being too complex to implement, and i'm being constrained by time and budget, prevented me from even attempting it.

• Raspberry Pi Pico
• KalumaJS as microcontroller framework and interface
• LoRa device E32-900T30D
• LED, LCD, and Button

1. Kaluma flashed to Pico
2. Program developed in typescript
3. Program transformed and bundled into javascript via esbuild
4. Javascript bundle flashed to Pico via serial communication (USB)

The hard part is when developing data-link layer, mainly in designing and implementing data communication protocol.
