How does it works
On Titino is mounted one ATTINY85 microcontroller, one 32 kbytes EEPROM and one RS485 driver. Titino will be connected to an Arduino and be able it to comunicate trought RS485 protocol in order to realize a Arduino network.
But Titino isn’t only a RS485 shield. The great function that improve Titino is to program Arduino trought the same RS485 network.
Today if you have several Arduinos installed in your home application, you need to reach each Arduino (often this is a very hard work), carry out a PC and program it, in order to upload a new sketch.
Thanks to Titino you only type (by using the serial monitor available on standard Arduino IDE) the command Program_ID=x, where x is the Titino network address.
Titino reply with a acknowledge message (“IDx_wait program”) and you simply press the upload button. ALL DONE!
Titino store the sketch in to its EEPROM memory, check if this is correct and then program the Arduino
