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。
Controlling a Digital Potentiometer Using SPI 在本教程中,您将学习如何使用串行外设接口(SPI)来控制AD5206 数字电位器。更多解释看到the SPI Library reference。 当你需要用电而不是用手来改变电路中的电阻时,数字电位器是有用的。示例应用包括LED调光,音频信号调节和音频生成。在这个例子中,我们将使用一个六通道...
This function should not be used in new projects. UseSPISettingswithSPI.beginTransaction()to configure SPI parameters. Sets the SPI clock divider relative to the system clock. On AVR based boards, the dividers available are 2, 4, 8, 16, 32, 64 or 128. The default setting is SPI_CLOCK_...

1 링크 번역 편집:An dosol2020년 7월 23일 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?

Re: ESP32 Arduino AD7705 SPI Library Postbyjgustavoam»Sat Feb 03, 2018 3:25 pm Hi , My suggestion is that you study AD7705 datasheet and convert Arduino Libray to ESP32 Library . http://www.analog.com/media/en/technica ... 5_7706.pdf ...
Copy the renamed folder to the Arduino sketchbook\libraries folder. TheAD9850SPIlibrary instantiates aDDSobject, the user does not need to do this. To use theAD9850SPIlibrary, the SPI library must also be included. #include<AD9850SPI.h>//http://github.com/F4GOJ/AD9850SPI#include<SPI.h...
1.网上的xpt2046都是使用默认的spi1接口。在arduino框架了SPI已经被定义就是默认的第一个spi接口。想要使用红牛版的spi2通道,需要重新定义一个spi实例,并且名字不能是SPI2(这个名字被stm32的库中用到了) 2 网上的库给xpt2046传递的的参数不对。 这是我改写后的 实验可以读出来。使用stm32 的spi2,pb12做模拟...
