Dashboard

Yes — for something as resource-constrained as a Raspberry Pi 1 and an STM32 Nucleo board, you’ll want a dashboard solution that’s extremely lightweight, can run on minimal RAM/CPU, and ideally supports serial or simple network communication.

Here are some good options:

1. PiDashboard (Custom Python + Flask + Lightweight JS)

Why: You can run a minimal Flask server on the Pi 1, serving a very basic HTML/JS dashboard.

How:

Pi reads data from STM32 via UART, USB CDC, or SPI.

Flask serves a static HTML page with minimal JavaScript (e.g., Chart.js or even plain SVG).

No heavy frameworks — keeps CPU usage low.

Pros: Fully customizable, very low footprint, works offline.

Cons: Requires some coding.

2. Node-RED (with minimal nodes)

Why: Node-RED can run on Pi 1 if you strip it down — disable unused nodes and avoid heavy dashboards.

How:

Use serial node to read STM32 data.

Use ui dashboard nodes for simple charts and gauges.

Pros: Visual programming, quick to prototype.

Cons: Still heavier than pure Python, so you must optimize.

https://mischianti.org/waveshare-rp2040-zero-high-resolution-pinout-and-specs/#google_vignette

3. Kiosk-style Static Dashboard (HTML + Auto-refresh)

Why: The lightest possible — no backend logic on Pi except a script writing JSON/CSV to disk.

How:

STM32 sends data to Pi.

Pi writes it to a file.

A static HTML page (opened in a lightweight browser like Midori) reads the file and updates via JavaScript.

Pros: Almost zero CPU load, works even on Pi Zero.

Cons: No fancy interactivity unless you add it manually.

💡 Tip for STM32 side: You can use STM32CubeProgrammer or a simple UART printf to send sensor data in CSV/JSON format — makes parsing on the Pi trivial.

If you want, I can sketch you a minimal Python+Flask dashboard that will run on a Pi 1 and display live STM32 data without stressing the CPU. Would you like me to do that?

Projects list:

Mecrisp is a play on words, it comes from MSP and french "écris", 
which means "you write", in the sense of "you write to the MSP430".

Special projects included here:

mecrisp-ice... runs on Lattice HX1K and HX8K FPGAs.

mecrisp-across... is a new still highly experimental Forth cross compiler
                  for small MSP430 targets featuring global optimisations.

Target literature package for... contains a collection of necessary and
                  useful datasheets for your favourite target chip.

loran-c... contains an experimental software defined Loran-C 
           longwave radio navigation receiver running on STM32F407.

mecrimus-b-0.5.tar.gz is the latest bit-bang USB code for MSP430.

wuseldraht-scurrywire-0.1.tar.gz is an implementation of a
           field bus for combined power and data transmission
           over long, high capacitance wires.
