Hey, I recently found this code below to play with LIS3DH, when I upload it, an error "ACAngle.h: No such file or directory" appeared. I know this should be related to library. But I do not know which library should be include here. Could anyone do me a favour here? Thanks.
PS, I did not find any ACAngle thing in Adafruit_LIS3DH library.
// AC Libs
#include <Wire.h>
#include <SPI.h>
#include <Adafruit_LIS3DH.h>
// PINS
// 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
Adafruit_LIS3DH lis = Adafruit_LIS3DH(LIS3DH_CS, LIS3DH_MOSI, LIS3DH_MISO, LIS3DH_CLK);
#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
class ACAngle {
public:
ACAngle(){};
void init();
void getValues (uint16_t *roll, uint16_t *pitch);
};
void ACAngle::init() {
//Serial.println("LIS3DH test!");
if (! lis.begin(0x18)) { // change this to 0x19 for alternative i2c address
//Serial.println("Couldnt start");
}
//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 ACAngle::getValues(uint16_t *roll, uint16_t *pitch) {
lis.read(); // get X Y and Z data at once
// angle calculation
*roll = 180 + atan2(-lis.x, lis.z) * 180/ PI;
*pitch = 90 + atan2(lis.y, sqrt( pow(lis.x, 2) + pow(lis.z, 2) )) * 180/ PI;
}
