What is single wire interface module?
SWP is an interface between contactless frontend (CLF) and universal integrated circuit card (UICC/SIM card chip). It is a contact-based protocol that is used for contactless communication. C6 pin of UICC is connected to CLF for SWP support.
What is 1-Wire connection?
1-Wire is a voltage-based digital system that works with two contacts, data and ground, for half- duplex bidirectional communication. Compared to other serial communication systems such as I2C or SPI, 1-Wire devices are designed for use in a momentary contact environment.
What is 1-Wire eeprom?
The DS2431 is a 1024-bit, 1-Wire® EEPROM chip organized as four memory pages of 256 bits each. Data is written to an 8-byte scratchpad, verified, and then copied to the EEPROM memory. The DS2431 communicates over the single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol.
What command can you use to confirm 1-wire is working?
Slaves confirm their presence by sending an ATR signal, which is done by holding the line low. The master samples the bus, and if the bus reads low, then at least one slave device is present. Reset Reset the 1-Wire bus slave devices and prepare them for a command.
What is SWP interface?
The Single Wire Protocol (SWP) is a method of Near Field Communication (NFC) which provides an interface between the SIM Card and a cell phone’s contactless front-end chip (CLF). SWP enables contactless communication between devices.
How does a single wire alternator work?
As you might assume, the concept behind a one-wire alternator is that there is a single wire used to connect the alternator to the battery. The voltage regulator is internal, and there are no other wires that need to be connected to your electrical system.
What is a 1-Wire carrier landing?
The “ONE WIRE” is there just in case the aeroplane driver drops below ideal glide path, or in heavy seas, the ship comes up to greet him/her. If the pilot aims for the 1 wire, the chances of the plane hitting the “Round down” are greatly enhanced.
What command can you use to confirm 1 wire is working?
Is 1 wire the same as i2c?
1-Wire is similar in concept to I²C, but with lower data rates and longer range. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments. A network of 1-Wire devices with an associated master device is called a MicroLAN.
