INA226编译错误

丿小广

我用的是例程啊，为什么会出现编译错误呢？？？程序：
/*    INA226 Bi-directional Current/Power Monitor. Alert Example.
https://cjmcu.taobao.com
*/

#include <Wire.h>
#include <INA226.h>

INA226 ina;

void setup()
{
  Serial.begin(115200);

  Serial.println("Initialize INA226");
  Serial.println("-----------------------------------------------");

  // Default INA226 address is 0x40
  ina.begin();

  // Configure INA226
  ina.configure(INA226_AVERAGES_1, INA226_BUS_CONV_TIME_1100US, INA226_SHUNT_CONV_TIME_1100US, INA226_MODE_SHUNT_BUS_CONT);

  // Calibrate INA226. Rshunt = 0.01 ohm, Max excepted current = 4A
  ina.calibrate(0.01, 4);

  // Enable Bus Over-Voltage Alert
  // ina.enableBusOvertLimitAlert();
  // ina.enableBusUnderLimitAlert();
  // ina.setBusVoltageLimit(3.33);

  // Enable Shunt Over-Voltage Alert
  // ina.enableShuntOverLimitAlert();
  // ina.enableShuntUnderLimitAlert();
  // ina.setShuntVoltageLimit(0.0055);

  // Enable Power Over-Limit Alert
  ina.enableOverPowerLimitAlert();
  ina.setPowerLimit(0.130);

  // ina.setAlertInvertedPolarity(true)
}

void loop()
{
  Serial.print("Bus voltage:   ");
  Serial.print(ina.readBusVoltage(), 5);
  Serial.println(" V");

  Serial.print("Bus power:     ");
  Serial.print(ina.readBusPower(), 5);
  Serial.println(" W");

  Serial.print("Shunt voltage: ");
  Serial.print(ina.readShuntVoltage(), 5);
  Serial.println(" V");

  Serial.print("Shunt current: ");
  Serial.print(ina.readShuntCurrent(), 5);
  Serial.println(" A");

  Serial.println("");
  delay(1000);
}
