How Does The 1-Wire Switch Click Board™ Work?
The 1-Wire Switch Click Board™ is based on the DS2413, a dual-channel addressable switch from Analog Devices. The DS2413 combines two programmable I/O pins and a fully featured 1-Wire interface in a single package, ensuring that PIO output changes occur error-free. The PIO outputs are configured as open-drain, operate at up to 28V (provide a high level of fault tolerance in the end application), and have an ON-resistance of 20Ω maximum. By monitoring the voltage at its programmable I/O pins, the DS2413 lets you read back the state of the load, in this case, the state of the button, which in this configuration is in the role of input, while the output state is visually detected through the red LED marked with OUT.
The DS2413's power is supplied parasitically from the 1-Wire bus, a system with a single bus controller and one or more peripherals. With that in mind, this Click board™ has one additional unpopulated header, which enables the connection of other external 1-Wire devices, thus forming a line with several peripherals on one controller. The DS2413 also has a 64-bit long registration number that guarantees unique identification. This number addresses the device in a multidrop 1-Wire network environment, where multiple devices reside on a common 1-Wire bus and operate independently.
As mentioned, the 1-Wire Switch Click Board™ communicates with MCU using the 1-Wire interface that, by definition, requires only one data line (and ground) for communication with MCU. The 1-Wire communication line is routed to the SMD jumper labelled as I/O SEL, which allows routing of the 1-Wire communication either to the GP0 pin or the GP1 pin of the mikroBUS™ socket. These pins are labelled, respectively, the same as the SMD jumper positions, making the selection of the desired pin simple and straightforward.
The 1-Wire Switch Click Board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
