The PCA9698 is an I2C, 40 pins parallel IO expander. These 40 pins can be configured as INPUT or OUTPUT and are addressable via 5 banks (groups) of 8 IO pins. The library provides read/write access to ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

The I2C and I3C interconnect technologies are close cousins, both conceived as interfaces for short-haul (intra-board) communication between integrated circuits and other digital devices. As we shall ...

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

The inter-IC bus, or I2C bus for short, is a two-wire bus designed for connecting simple peripherals that do not require rapid transfer of large amounts of data. In this three-part series we will look ...

TM1637 is a kind of LED (light-emitting diode display) drive controller special circuit with a keyboard scan interface. It is internally integrated with MCU digital interface, data latch, and LED high ...

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your Arduino, or any microcontroller ...

Developers, engineers and Arduino enthusiasts may be interested in a new open source piece of hardware designed for CAN bus Arduino projects. Combining several essential features into one complete ...
