Hello, sorry for my maybe stupid question. how does the communication between the Arduino part and the Linux part on the Udoo-board? In detail: if I want to access in an arduino-sketch on a database (mysql) from Linux or raspberry, then I need normal a Ethernet shield for the arduino and the communication take over TCP/IP. how use this Udoo? is the short-way integrated? if so, then I don't need an additional Ethernet shield as with the combination arduino + raspberry (if the sketch use a database) how do I imagine it? oh yes, I congratulate you for the great idea to pack both devices on a board regards Jürgen
The two part are connected via serial !!!! So if you want to log data via mysql , the arduino part collects the data using it`s hardware ports ( analog etc ) and sends the data via serial to the Multi-core part which saves the data etc. A real life example .. You want to display some useful data on a set of leds connected to the arduino part , this data is the number of torrent you are downloading plus the number of unread gmails . 1/ Install firmate on the arduino part , which will allow you to easy control and collect data from the arduino. 2/ Make a python program and load the firmata library and check the number of torrents , checks how many unread gmail . ( they other libraries for firmata ) 3/ control the leds 4/ wait a while and repeat !!!
this is my project with node.js in Browser https://github.com/RickorDD/udoocontrol It is synchron with all connected browsers and load and save the switchstate in a sqlite file. Screen in attachment.
