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
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。
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。 unsigned long pulseIn(pin, ...
Software SPI Example Visit the SoftSPI repositories and download the entire repo to your local drive. Now, the SoftSPI library can be installed to the Arduino IDE. Open the Arduino IDE, and click sketch -> Include Library -> Add .ZIP Library, and choose the SoftSPI file that you've...
每块Arduino板至少有一个串口。串行通信发生在数字引脚0(RX)和1(TX)以及USB上(所以,插上数据线就可以上传程序)。Arduino也支持通过数字引脚与SoftwareSerial Library(Arduino的一个库 还记得前面程序里说的Serial 库吗?应该有些联系) 进行串行通信。这允许用户连接多个支持串行的设备,并保留主串行端口可用于USB。
Arduino is the popular open-source electronics prototyping platform based on easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments and is designed to be as flexible as possible to fit your project'...
