RP2040 USB Sensor Data Streaming

@engrusmanfaiz

I can modify your RP2040 filament sensor firmware to stream raw data directly over USB serial, bypassing Klipper integration. I will analyze the roadrunner-filament-sensor codebase and refactor the communication layer for clean USB CDC output. Real-time parameters like AS5600 angle, accumulated turns, and IR filament detection will be formatted and streamed reliably. Data structure will be optimized (CSV/JSON) for easy parsing on your laptop. I will ensure stable timing and non-blocking transmission using RP2040 USB stack. Optional filtering or scaling can be added for cleaner readings. I can also provide a simple Python script for live monitoring and logging. Code will remain clean, documented, and easy to extend. Ready to start immediately and deliver quickly.

Hi there, I’m Ivaylo, and I’m excited about your RP2040-based filament sensor project. I’ll help you bridge your open-source roadrunner-filament-sensor firmware to a direct USB data stream so you can read real-time raw values on your laptop without Klipper. Here’s the plan I propose: - Assess the existing USB-serial footprint in the firmware and extend it to expose a lightweight, high-rate data channel (angle, accumulated turns, filament presence) via a USB CDC endpoint. The goal is a clean, low-latency stream that your laptop can parse with a simple Python script. - Implement a small, well-documented protocol layer: optional JSON or compact binary frames, timestamping, and a simple command set to request status, reset counters, or switch streaming modes. - Ensure safe, non-disruptive operation: preserve current behavior for the Klipper path but enable direct USB access when connected to a PC. I’ll include a toggle or auto-detect feature so you can switch between modes easily. - Provide example PC-side tooling in Python to read, decode, and visualize angle, turns, and presence in real time, with hooks for logging and analysis. This work will be grounded in your existing C codebase, with careful testing on a dev board and clear firmware documentation for future maintenance. Best regards, Ivaylo

Hello, Hope you are doing fine. I have strong experience with RP2040 firmware (C/C++ SDK) and USB serial communication. I will modify the open‑source roadrunner‑filament‑sensor firmware to stream raw sensor data directly over USB to your laptop. My approach: - Pull the GitHub repository and locate the USB serial version. - Add code to read angle, accumulated turns, and filament presence from AS5600 and IR sensor. - Format and output the data as plain text (e.g., CSV) over the USB serial interface at a configurable rate. - Retain the option to disable the Klipper protocol or replace it with the streaming mode. - Test and provide a compiled UF2 file, plus instructions for building and flashing. I will deliver a modified firmware source and a brief guide to get raw data on your laptop (using a simple serial terminal or Python script). Let’s discuss any details in chat so we can move forward. Best regards, Md Ruhul Ajom

Hi, RP2040 firmware development and USB serial communication is something I work with regularly, I have recent hands-on experience with the RP2040 on a custom board project. I have looked at the roadrunner-filament-sensor repo and the approach is straightforward: add a USB CDC serial output path that periodically broadcasts the AS5600 angle, accumulated turns, and IR presence values as a structured text or binary stream. The Klipper-specific protocol stays untouched, so you keep the option open, and you get clean raw data on any serial terminal or Python script on your laptop. Can start immediately. Please feel free to reach out. Himanshu

Hello, I’ve reviewed your project and I can help you modify your firmware to stream real-time data (angle, rotation count, and filament presence) directly over USB to your laptop. I will: • Integrate AS5600 sensor reading (I2C) and IR sensor input • Implement real-time data streaming over USB serial (CDC) • Format output cleanly (CSV or structured text for easy parsing) • Keep the code well-organized and documented I don’t have the exact hardware setup locally, so I will develop and validate the firmware logic and USB communication, and I’ll work closely with you for quick testing on your side. I’ll support iterations to ensure everything works correctly on your device. I can start immediately and deliver quickly.

@slavkom1

Hi, I read about your RP2040 sensor setup and what you need sounds clear. You want the firmware changed so the board streams angle, turn count, and filament presence over USB without relying on Klipper. I’ve worked on RP2040 and similar encoder firmware before, so I’m comfortable digging into the GitHub code and wiring the data flow to USB serial. I’d handle it by: - reviewing the roadrunner code paths for AS5600 and IR - adding a clean USB serial output loop - defining a simple structured stream format - testing live output on a laptop with a small Python script I can start now and this should only take a short window to get running. Which data format do you prefer for the USB stream so it’s easy to parse on the host side? Greetings, Slavko

Hello, I’d be glad to help modify your **RP2040 filament sensor firmware** so you can stream raw data directly over USB without relying on Klipper. I’m a full-stack developer with experience in **C, embedded systems, microcontrollers (RP2040), USB serial communication, and sensor data processing**, with a strong focus on working with existing open-source firmware. One of the key challenges here is ensuring that **AS5600 angle data, accumulated turns, and IR filament presence are captured reliably and streamed in real time over USB serial in a clean, parseable format without affecting timing or sensor accuracy**. My approach is to extend the current firmware to output structured serial data (e.g., CSV or JSON), implement a stable read loop, and optionally provide a simple Python script to monitor and log the data on your laptop. My goal is to make the device behave like a **plug-and-play USB data source**, giving you clear real-time insight into sensor values. Quick question: do you prefer the output format as **simple CSV (lightweight)** or **JSON (more structured for future use)**? Best regards, Carlos

Hello, The primary challenge lies in ensuring reliable data transmission from the RP2040 over USB while maintaining real-time performance. Additionally, handling the raw data from the AS5600 encoder and IR sensor requires careful management of data integrity and synchronization. How is the current USB communication structured within the firmware? Will the data format for the angle, accumulated turns, and filament presence need to be standardized for easy parsing on the laptop? I look forward to discussing the firmware architecture and integration points further.
