Romilly Cocking's MicroPlot Brings Simple Graphical Plotting to MicroPython on the Raspberry Pi Pico
Designed for simple graphical data representation, the current version of MicroPlot does line plots and can save bitmap images.
Maker Romilly Cocking has published a tool, dubbed MicroPlot, which brings graphical plotting to MicroPython — starting with initial support for the Raspberry Pi Pico and Pimoroni's display-equipped Pico Explorer add-on.
Launched late last month, the Raspberry Pi Pico — the first microcontroller board from Raspberry Pi, and the first device to host its in-house RP2040 silicon has proven popular, powering a range of projects and with companies keen to launch both add-on gadgets and RP2040-powered boards of their own.
As the platform matures, it's getting an increasing amount of software and hardware support — and Cocking's MicroPlot is designed for as-simple-as-possible graphical plotting on a connected display.
In its present version, MicroPlot runs within MicroPython on the Raspberry Pi Pico - though it should, in theory, be portable both to other RP2040-based devices and other MicroPython-compatible microcontrollers. The software offers monochrome line plots, plus bitmap generation — and Cocking has a range of other features he's looking to add. "Lots more to do," Cocking writes: "Colours, other plots, other displays, support for Adafruit CircuitPython."
The source code for MicroPlot is available on Cocking's GitHub repository, under the permissive MIT license.
