Device for automatically detecting coupling between electronic devices
A method for automatically detecting a sensor coupled to an electronic computer including steps of detecting the sensor and steps of configuring a hardware interface.
1 . An electronic computer comprising:
a first computer pin:
a second computer pin:
a third computer pin; and
a fourth computer pin; and
a hardware interface, coupled to the electronic computer, the hardware interface adapted to:
detect and identify a type of sensor coupled to the first computer pin, the second computer pin, and the third computer pin, and
then, in response to a change in state of a signal received by the hardware interface and the computer, store said detected type of sensor in the hardware interface, wherein the signal received by the hardware interface and the computer comprises a boot-up signal.
2 . The electronic computer as claimed in claim 1 , wherein the boot-up signal is representative of an end of a booting up the computer.
3 . A method for automatically detecting of a sensor coupled to an electronic computer as claimed in claim 1 , the method comprising:
a first step e1), of detecting that the electronic computer is inactive;
a second step e2), of detecting-a supply electric power to the electronic computer and moving to a third step e3) when the supply of electric power to the electronic computer is detected;
the third step e3), of detecting a type of sensor coupled to the pins of the electronic computer;
a fourth step e4), of scanning a signal received by the electronic computer, wherein the signal is representative of an end of a booting up the electronic computer; and
a fifth step e5), of storing, in response to scanning the signal received by the electronic computer, the type of sensor detected as coupled to the terminals of the electronic computer in step e3).
4 . The method of claim 3 , wherein the scanning of step e4) is at an input of a storage module of the electronic computer.
5 . The electronic computer as claimed in claim 1 , wherein the hardware interface comprises:
a detection module for detecting the type of sensor coupled to the pins of the electronic computer; and
a storage module for storing the type of sensor detected by the detection module.
6 . The electronic computer as claimed in claim 5 , in which the storage module is a D flip-flop.
7 . The electronic computer as claimed in claim 5 , wherein the computer boot-up signal is representative of an end of a booting up the computer.
