dualshock/WIP NOTES.txt

Node.js module for DualShock (3 and 4) controllers.

Battery:
The DS3's battery percentage is only accurate to 20%, so the only possible values of this are 0, 20, 40, 80, and 100.

//TODO:
- Make parseAnalog and parseMotion more effecient by for loop itterating over map instead of data.
- Anything to do with vMax in parseMotion?
- Handle 'controller not found' and other errors more smoothly.
- Battery status.
- Seperate callback for each type of event (motion, button, analog)
- Use max and min instead of bits.
- Move supList entries to separate files, as well as the custom functions like ds3 and ds4 api functions.
- ACTUALLY WRITE DOCUMENTATION
- Add example for syncronous reading from prevDigital, prevAnalog, etc. instead of using async callbacks.
- ds.getType without providing type should list all supported controllers regardless of type.

Maybe useful (somewhere else) functions:

//function isDS3(dev) { return dev.vendorId == 1356 && dev.productId == 616; }
//function isDS4(dev) { return dev.vendorId == 1356 && dev.productId == 1476; }
//function isRumblePad(dev) { return dev.vendorId == 1133 && dev.productId == 49689; } //TEMP
//function lsMax(arr) {for(var i=0,l=arr.length,m=0,p=0;i<l;i++)if(arr[i]>m)m=arr[i],p=i;return [m,p]}
//function lsOrder(a) {var r=[];while(a){var m=lsMax(a);r.push(m[0]);a.splice(m[1],1)}return r}
/*function objGet(obj, find) {
	var kl = Object.keys(obj);
	for(var i=0,l=kl.length; i<l; i++) { if(obj[kl[i]] == find) return kl[i]; }
	return false;
}*/
