ADNS-2051 configuration help

Jeff Pearson · Jan 22, 2018

I would have been totally lost without the Arduino IDE software. I do have a question. Here is a page from the ADNS2051 data sheet and my sketch so far. ADNS2051.h is in the Optimouse library. How do I send the configuration to the ADNS2051. Specifically, I want to make sure the RES is set to 800 counts per inch, and would like to set Sleep to Always awake. What is the line of code to put in the sketch. Thank you in advance

// ADNS2051.h reads out ADNS-2051 the Optical Navigation Sensor
// It's used in many cheap optical mice

#include "ADNS2051.h"
#include <Bounce.h> // Create Bounce objects for each button. The Bounce object
// automatically deals with contact chatter or "bounce", and
// it makes detecting changes very simple.

#define SCLK 0 // Serial clock pin on the Arduino
#define SDIO 1 // Serial data (I/O) pin on the Arduino

ADNS2051 Optical1 = ADNS2051(SCLK, SDIO); // Create an instance of the ADNS2051 object

Bounce button2 = Bounce(2, 10); // if a button is too "sensitive"
Bounce button3 = Bounce(3, 10); // to rapid touch, you can
Bounce button4 = Bounce(4, 10); // increase this time.
void setup()
{
Serial.begin(38400);
Optical1.begin(); // Resync (not really necessary?)

pinMode(2, INPUT_PULLUP); // Left Mouse Click
pinMode(3, INPUT_PULLUP); // Middle Mouse Click
pinMode(4, INPUT_PULLUP); // Right Mouse Click
}

void loop()
{
button2.update();
button3.update();
button4.update();

if (button2.fallingEdge()) {
Mouse.press(MOUSE_LEFT);
}
if (button2.risingEdge()) {
Mouse.release(MOUSE_LEFT);
}
if (button3.fallingEdge()) {
Mouse.press(MOUSE_MIDDLE);
}
if (button3.risingEdge()) {
Mouse.release(MOUSE_MIDDLE);
}
if (button4.fallingEdge()) {
Mouse.press(MOUSE_RIGHT);
}
if (button4.risingEdge()) {
Mouse.release(MOUSE_RIGHT);
}

// The status commands are available only for the PAN3101 and the ADNS2051:

Optical1.updateStatus(); // Get the latest motion status
if (Optical1.motion()) // If the 'Motion' status bit is set,
{

Mouse.move(-1*Optical1.dx(), -1*Optical1.dy());

}
}

Wow, I figured it out. First of all I,m using the OptiMouse-master library from Github, which has support for 5 different mouse sensors. The "extra commands" were written for the ADNS2620 in that library, and I had looked at examples for other mouse sensor libraries that sent configuration data. I added lines to ADNS2051.cpp ADNS.h and Optical1.writeConfig(B000101); in the setup of my sketch which sets 800 counts per inch and always awake. WooHoo. I am a complete total noob to this so I really impressed myself. Now I can get on with setting up a thumbstick for scrolling :-D

Am I supposed to send this upstream to Github????
