The Musical Instrument Digital Interface has a great acronym that is both nice to say and cleanly descriptive. The standard for talking to musical instruments relies on a serial signal at 31250 bps, which makes it easy to transmit using any old microcontroller UART with a settable baud rate. However, [Kevin] has dived into explore the […]

The following short Python programs will demonstrate essential operation of the Raspberry Pi Pico board. These assume one or more binary input or output circuits are externally attached. Each can be run by copying the program into code.py on the CIRCUITPY drive offered by the board. The text can be pasted directly from this page, or each

This sketch demonstrates an example of accelerometer data processing using a classification tree. The classifier code was generated using the Python script classifier_gen.py using recorded and labeled training data. The underlying classification tree was automatically generated using the Python scikit-learn library. The purpose of the classifier is to categorize a multi-dimensional data point into an integer representing membership within

The navigation methods currently employed by many autonomous vehicle companies such asGoogle, Uber, and Telsa rely upon manually driving roadways and gathering information aboutthe roadway infrastructure with lidar before any autonomous navigation is possible. While thismethod can be very effective, issues can arise when the roadway undergoes changes such as duringconstruction or road closure. Additionally,

You could argue that the project to add a round screen to a Raspberry Pi from [YamS1] isn’t strictly necessary. After all, you could use a square display with a mask around it, giving up some screen real estate for aesthetics. However, you’d still have a square shape around the screen and there’s something eye-catching about a

IMAGE PROCESSING DETAILS The OTS MGS evolved across three main iterations. The driving system requirement of these iterations was processing all image analysis and feedback within 100ms per frame, or 10fps. First Iteration: Image processing starts with the loading of a video frame into memory as an image file. The microcontroller then iterated through the
