Benchmarks for BeagleBone Black GPIO with Python, C, C++, and Shell @beagleboardorg
Code and Life ran some benchmarks on the BealgeBone Black’s GPIOs using multiple libraries, including Adafruit’s own Adafruit_BBIO Python Library. The results are useful for any maker looking for existing benchmarks that compare and contrast multiple languages and libraries, for their own projects.
The test is a basic “toggle one GPIO pin as fast as possible”. It does not measure multiple pin performance, input performance or the capabilities of built-in hardware capabilities like I2C communications or PWM which might operate on significantly higher speeds. It basically tells that with benchmark speed of 1 kHz, you can expect 2000 toggles per second on that programming language, or on average 0.5 ms for a single toggle.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
