在嵌入式系统中，串行外设接口（Serial Peripheral Interface，SPI）及其扩展（如 DSPI 和 QSPI）被广泛应用于与外部设备（如传感器、存储器、LCD 控制器等）高速通信。 SPI（Serial Peripheral Interface）是一种全双工同步串行通信协议，通常由主设备（Master）和从设备（Slave ...

SPI 是英语Serial Peripheral interface的缩写，顾名思义就是串行外围设备接口。是Motorola(摩托罗拉)首先在其MC68HCXX系列处理器上定义的。 SPI，是一种高速的，全双工，同步的通信总线，并且在芯片的管脚上只占用四根线，节约了芯片的管脚，同时为PCB的布局上节省 ...

Electronics is everywhere, especially these days. Many times, as frequent users, we do not even notice a “paradigm change” in the things we use on regular basis. We use a fridge, but we do not care ...

Considering that the Serial Peripheral Interface bus semi-standard has been around since the early 1980s, it’s perhaps not that shocking that the controllers of the Super Nintendo ...

The MAX3420E contains the digital logic and analog circuitry necessary to implement a full-speed USB peripheral compliant to USB specification rev 2.0. A built-in full-speed transceiver features ±15kV ...

SPI (Serial Peripheral Interface) Flash is the serial synchronous communication protocol developed by SPI Block Guide V04.01. SPI Flash VIP can be use ...

In the last video I demonstrated a Universal Active Filter that I could adjust with a dual-gang potentiometer, here I replace the potentiometer with a processor controlled solid-state potentiometer.

The 23LCV1024 is a 1 Mbit Serial Peripheral Interface (SPI) serial SRAM with battery backup and SDI interface. The memory of the device is accessed via a simple SPI compatible serial bus. The bus ...

When looking at protocol information on a bus, an oscilloscope may not be the first instrument to come to mind�until now. As most engineers know, digital oscilloscopes are an indispensable ...

Check out LIN and I2C for low speed networking needs. They are often better alternatives than SPI or CAN for many applications. The serial peripheral interface (SPI) and universal asynchronous ...
