Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

At L-3 Communications, we use PLLs (phase-locked loops) in many of our products to generate precise, stable signals. To program these parts, we must load several control registers with digital words ...

The SC16IS741 is a single channel universal asynchronous receiver/transmitter (UART) with a slave I²C-bus interface or serial peripheral interface bus (SPI-bus) interface. It features 64 bytes of ...

Introduction: Serial to Peripheral Interface (SPI) is a hardware/firmware communications protocol developed by Motorola and later adopted by others in the industry. Microwire of National Semiconductor ...

Maxim has introduced a chip to interface devices equipped with I2C or SPI bus connections to its ‘1-wire’ bus. Called DS28E18, it is intended to knock cost out of networks that connecting I2C and SPI ...

The serial peripheral interface (SPI) bus is a synchronous, full-duplex, serial data link commonly used for the short-distance data exchange between a master device, such as a microcontroller unit ...

VIA's upcoming VT8237S south-bridge will implement a serial bus that will allow easy BIOS flashing for the likes of system integrators and motherboard manufacturers. Generally speaking, there are two ...

Fig 1. An SPI-based output driver (in this case, an L9822 octal relay driver from STMicroelectronics) can be used to provide a random mix of I/O pins at the chip’s output. The circuit in (a) senses a ...
