小白初次发帖，请教各位

在网上找了很多关于ADXL345通信的例子，不过都是用IIC编写的，希望能有高手能在空闲之余帮忙用SPI协议编写一下。小弟写了一段代码但是无法读取到器件的ID号，X Y Z的数据也不对，不知哪里有问题，希望路过的大侠能帮忙看看，感激不尽[pre lang="arduino" line="1" file="code"]#include<SPI.h>
#define DEVID 0x00

const int salveSelectPin = 10;
const int dataReadyPin = 8;
volatile int state = LOW;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  pinMode(salveSelectPin, OUTPUT);
  pinMode(dataReadyPin, INPUT);
  digitalWrite(salveSelectPin, HIGH);
  delay(10);
  attachInterrupt(8, blind, RISING);
  SPI.setBitOrder(LSBFIRST);
  SPI.setDataMode(SPI_MODE3);
  SPI.begin(10);
}

void loop() {
  // put your main code here, to run repeatedly:
  byte dataX ;
  byte dataY ;
  byte dataZ ;
  byte dataDEVID ;
  digitalWrite(salveSelectPin, state);

  if (Serial.available());
  dataX = SPI.transfer(10, 0x33, SPI_CONTINUE); //<< 8 + SPI.transfer(10, 0x32);
  dataY = SPI.transfer(10, 0x35, SPI_CONTINUE); //<< 8 + SPI.transfer(10, 0x34);
  dataZ = SPI.transfer(10, 0x37, SPI_CONTINUE); //<< 8 + SPI.transfer(10, 0x36);
  dataDEVID = SPI.transfer(10, 0x00);
  { char a = Serial.read();
    if (a == 'K')
      Serial.print("dataX=");
    Serial.println(dataX);
      Serial.print("dataY=");
      Serial.println(dataY);
      Serial.println(dataDEVID);
      Serial.print("dataZ=");
      Serial.println(dataZ);
  }
}[/code]
另外小弟对寄存器的读写操作不是很清楚，希望有老师能用代码讲解一下，再次谢谢！
