Hi guys, 

I've written a driver for the ADXL362 chip. I bought mine from Sparkfun.

 

Here is an example of how to set it up to raise events when it is moved, and again when it is put back to rest.

ADXL362Accelerometer accelerometer = new ADXL362Accelerometer(Pins.GPIO_PIN_D10, Pins.GPIO_PIN_D1, Pins.GPIO_NONE);
accelerometer.OnInt1Changed += accelerometer_OnInt1Changed;
accelerometer.ConfigureMotionActivatedSleep();

I've included predefined configurations for the examples used in the datasheet and the Arduino driver. The others are:

accelerometer.ConfigureAutoMotionSwitch();
accelerometer.ConfigureFreeFall();
accelerometer.ConfigureSimpleRead();
accelerometer.ConfigureTiltOnOff();

The chip also has a temperaturesensor, and you can read the current XYZ values.

 

The class is attached - hope someone finds it useful

Hi Frode,

 

Great work on the driver

 

I'm trying to convert your driver for use with my ADXL345 (http://www.adafruit.com/products/1231), and I want to use it with I2C instead of SPI.

From what I can see I need to rewrite all the SPI methods and the ADXL362Accelerometer method, for use with I2C.

 

Would I be so lucky that you have some experience in creating I2C drivers?

Hi Esben, you should take a look at the SSD1306 driver (for an OLED display). It was originally written for SPI, and then expanded to I2C. If you look at that driver you'll get a sense of what you need to change from SPI to I2C.

 

The code in that thread has become a little garbled, I believe the forum broke a lot of the code examples a few weeks back :/

 

I took a quick look at the ADXL345 datasheet, and seems like the registeres are pretty different, so converting the ADXL362 driver will take some time and effort.

Hi Frode,

 

Thank you for the quick reply.

 

I have will have a look at the SSD1306 driver, you wouldn't happen to have a source file that isn't garbled?

[Frode]

Sure, you can download it from here.

Sure, you can download it from here.

 

Great, thank you!
