所以我试图从Arduino构建一个加速度计，这个错误信息不断从我下载的库中使用的基本入门代码中弹出。
这是图书馆的链接：

以下是入门代码：
#include <Wire.h>
#include <SPI.h>
#include <Adafruit_LIS3DH.h>
#include <Adafruit_Sensor.h>
// Used for software SPI
#define LIS3DH_CLK 13
#define LIS3DH_MISO 12
#define LIS3DH_MOSI 11
// Used for hardware & software SPI
#define LIS3DH_CS 10
//software SPI
Adafruit_LIS3DH lis = Adafruit_LIS3DH(LIS3DH_CS, LIS3DH_MOSI,
LIS3DH_MISO,LIS3DH_CLK);
//hardware SPI
Adafruit_LIS3DH lis = Adafruit_LIS3DH(LIS3DH_CS);
//I2C
Adafruit_LIS3DH lis = Adafruit_LIS3DH();
#if defined(ARDUINO_ARCH_SAMD)
// for Zero, output on USB Serial console, remove line below if using
programming port to program the Zero!
#define Serial SerialUSB
#endif
void setup(void) {
#ifndef ESP8266
while (!Serial); // will pause Zero, Leonardo, etc until serial
console opens
#endif
Serial.begin(9600);
Serial.println("LIS3DH test!");
if (! lis.begin(0x18)) { // change this to 0x19 for alternative i2c
address
Serial.println("Couldnt start");
while (1);
}
Serial.println("LIS3DH found!");
lis.setRange(LIS3DH_RANGE_4_G); // 2, 4, 8 or 16 G!
Serial.print("Range = "); Serial.print(2 << lis.getRange());
Serial.println("G");
}
void loop() {
lis.read(); // get X Y and Z data at once
// Then print out the raw data
Serial.print("X: "); Serial.print(lis.x);
Serial.print(" \tY: "); Serial.print(lis.y);
Serial.print(" \tZ: "); Serial.print(lis.z);
/* Or....get a new sensor event, normalized */
sensors_event_t event;
lis.getEvent(&event);
/* Display the results (acceleration is measured in m/s^2) */
Serial.print("\t\tX: "); Serial.print(event.acceleration.x);
Serial.print(" \tY: "); Serial.print(event.acceleration.y);
Serial.print(" \tZ: "); Serial.print(event.acceleration.z);
Serial.println(" m/s^2 ");
Serial.println();
delay(200);
}
