1. any one of the ADXLs alone or
2. any combination of the ADXLs simultaneously.
I started with the following code.
Can you help?
Thank you.
Code: Select all
#include <Wire.h>
#include <Adafruit_ADXL345_U.h>
#include <Adafruit_sensor.h>
/* Assign a unique ID to this sensor at the same time */
Adafruit_ADXL345_Unified accel = Adafruit_ADXL345_Unified(12345);
#define TCAADDR 0x70
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Wire.begin();
/* Initialise the sensor */
if(!accel.begin())
{
/* There was a problem detecting the ADXL345 ... check your connections */
Serial.println("Ooops, no ADXL345 detected ... Check your wiring!");
//while(1);
}
}
void loop() {
// put your main code here, to run repeatedly:
for (uint8_t t=0; t<5; t++) {
tcaselect(t);
Serial.println();
Serial.print("Sensor no : ");
Serial.println(t);
/* Get a new sensor event */
sensors_event_t event;
accel.getEvent(&event);
/* Display the results (acceleration is measured in m/s^2) */
Serial.print("X: "); Serial.print(event.acceleration.x); Serial.print(" ");
Serial.print("Y: "); Serial.print(event.acceleration.y); Serial.print(" ");
Serial.print("Z: "); Serial.print(event.acceleration.z); Serial.print(" ");Serial.println("m/s^2 ");
}
}
void tcaselect(uint8_t i) {
if (i > 7) return;
Wire.beginTransmission(TCAADDR);
Wire.write(1 << i);
Wire.endTransmission();
}
