What is ArduTV ?
ArduTV is an advanced electronic board designed in a shape and interface compatibility of an Arduino UNO (This Arduino expansion board are usually called "Shield").From Arduino board (or an Arduino compatible interface board) it takes the power supply of 5V (it can be configured to 3.3V if other kind of board are used)and the SPI interface (also it can work at 5V for Arduino standard or 3.3V for other standards).
ArduTV to be controlled needs only the SPI interface and it is able to generate a video signal that it can be connected to the televisions or monitors simply using the HDMI connector.
A simple Arduino Library is given to print on the screen shapes, texts, colors and points.
ArduTV Pinout
The mandatory connections are 5VDC and SPIs pins. The 3.3VDC must be connected if you are interfacing a 3.3V logic Board.NOTE: one 5VDC is needed also for the 3.3V logic board (USB direct power connection is also fine for powering).
Some HW Detail
RESULT: using a simple UNO (or more powerful boards), our library and few simple commands you have access to every televisions or monitors !
Using ArduTV
Once you connected an Arduino board to ArduTV and a television using HDMI cable you can write your own code with the standard IDE using the library
commands.
For a list of commands please visit the Arduino or Nucleo section.
Technical Note
Arduino boards generally have a very limited resources so, to save them, all the relevant video routines (including text fonts) are embedded inside the memory of ArduTV. In this way the space required to implement ArduTV commands is negligible and let free the memory for the coding.NOTE: the fonts can be updated runtime if necessary.
The FW of ArduTV can be easily updated for future improvements just using ONE Arduino board.
