In these lessons we got the hardware working, got to the point we could take data, and then got the NMEA sentences parsed, so that we could display understandable data for Latitude, Longitude, and Altitude. The Adafruit IO Python library will export the UART device tree overlays as a convenience. js with Debian Linux platform. Note que configuramos nossa machine como sendo a beaglebone (serve tanto para a white como a black), mudamos o diretório de download para podermos reutilizar os fontes baixados em outros projetos e usaremos o gerenciador de pacotes ipk (ele é mais indicado para sistemas embarcados porque não exige muitos recursos para funcionar). A classic example of an RS-232 line driver is MAX232. Thankfully, Adafruit has great tutorials for the BeagleBone, so we'll start with adapting the Python LED blink example. This post was written by Rui Santos and Luís Perestrelo authors of BeagleBone For Dummies. The BeagleBone Black is an outstanding tool for projects that involve the Internet. Re: UART with Python on BBB using Ubuntu by adafruit_support_mike on Wed Oct 16, 2013 12:52 am Angstrom uses a completely different setup to handle webpages, but it also comes with the built-in Plan9 IDE and Bonescript libraries to handle GPIO through a web interface. SeeedStudio BeagleBone Green Wireless has included. BeagleBone Blue. This document exists as a guide for reading from or writing to an SPI flash chip with the BeagleBone Black, using the flashrom software. I used Adafruit's python IO library to do this.
