SPI Library (通过串口外围借口SPI总线)使能设备之间的通信。更多的信息参考the Reference for the SPI Library page。适用于所有Arduino板,除了Arduino DUE。 Barometric Pressure Sensor: 通过SPI协议来读取一个传感器的空气压力和温度。 Digital Pot Control: 通过SPI协议控制一个AD5206 数字电位器。
// send in the address and value via SPI: SPI.transfer(address); SPI.transfer(value); // take the SS pin high to de-select the chip: digitalWrite(slaveSelectPin, HIGH); } [Get Code] 原教程由 Heather Dewey-Hagborg 制作, 由 Tom Igoe 和 Christian Cerrito 更新 更多 Arduino SPI LIbrary...
I have included the spi and sd libraries to make the sd card storage code into a function, but I get an error but, the other library is succeed Why can't only the spi and sd libraries included? I want to finally add spi and sd libraries in s-funtionbuild ...
If any of your settings are variables, you may create a SPISettings object to hold the 3 settings. Then you can give the object name to SPI.beginTransaction(). Creating a named SPISettings object may be more efficient when your settings are not constants, especially if the maximum speed is...
shiftOut(dataPin, clockPin, bitOrder, value) SPI外部IO扩展函数,通常使用带SPI接口的74HC595做8个IO扩展,dataPin为数据口,clockPin为时钟口,bitOrder为数据传输方向(MSBFIRST高位在前,LSBFIRST低位在前),value表示所要传送的数据(0～255),另外还需要一个IO口做74HC595的使能控制。

This Arduino library is for use with flash and FRAM memory chips that communicate using the SPI protocol. In its current form it supports identifying the flash/FRAM chip and its various features; automatic address allocation and management; writing and reading a number of different types of data...
