Posted on December 01, 2016 at 12:40I am having trouble getting the click interrupts to work for the LSM303D. using the library provided by Pololu for arduino I can get this code working for the DLHC
[code]
#include <Wire.h>
#include <LSM303.h>
long thisLong = 0;
LSM303 compass;
const byte interruptPin = 2;
void setup()
{
Serial.begin(9600);
Wire.begin();
compass.init();
compass.enableDefault();
compass.writeAccReg(LSM303::CTRL3, 0b11000000);
compass.writeAccReg(LSM303::CTRL0, 0b00000000);
compass.writeAccReg(LSM303::CLICK_CFG, 0b00010000);
compass.writeAccReg(LSM303::CLICK_THS, 0b00011111);
compass.writeAccReg(LSM303::TIME_LIMIT, 0b00011111);
delay(100);
attachInterrupt(digitalPinToInterrupt(interruptPin), reset, CHANGE);
}
void loop()
{
Serial.print(thisLong);
Serial.println('''');
thisLong++;
delay(100);
}
void reset() {
thisLong = 0;
}
[/code]
But when I try it on the LSM303D it doesn't seem to generate the interrupt. I can read the CLICK_SRC register and the interrupt shows active, but the INT1 pin never goes from low to high. Anyone work with these at all?
