In daily’s development,abbreviations are normal in judging different usages.It can be important to know the abbreviations’ full names.And I will update for a long time in this pages.

Signal Processing:

PWM - Pulse Width Modulation 脉冲宽度调制

CCP - Capture Compare PWM 捕获比较脉宽调制

PCA - Programmable Counter Array 可编程计数器阵列

Serial Communication Protocols:

SPI - Serial Peripheral Interface Bus 串行外设接口 ： SCLK - Serial Clock 串列时脉 ; MOSI - Master Output Salve Input 主机输出从机输入 ; MISO - Master Input Salve Output 主机输入从机输出到 ; SS - Salve Selected 从机选择。

IIC Bus - Inter-Integrated Circuit Bus 集成电路总线 : SDA - Serial Data Line 串行数据线 ; SCL - Serial Clock Line 串行时钟线。

UART - Universal Asynchronous Receiver/Transmitter 通用异步收发传输器 : VCC - Voltage Common Collector 电压公共收集器 ; GND - Ground 接地 ; TX - Transmit 传送 ; RX - Receive 接收。

CAN Bus - Controller Area Network Bus局域网控制器总线。
