While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

This API is forked from the original Python Arduino Command API to add support for Python 3. The Arduino-Python3 Command API is a lightweight Python library for communicating with Arduino ...

To prevent data corruption when using multiple SPI devices on the same bus, care must be taken to ensure that they are only accessed from within the main loop, or from the interrupt routine, never ...

Real-time data acquisition from Arduino over serial and frequency analysis using the Fast Fourier Transform (FFT). Built as a practical signal processing toolkit for embedded sensor systems. Captures ...
