Will it be for sale?

You need a process (driver) in the PC that acts as an intermediate

AFAIK, the DUE has problems with I2C  but I never dived into the details.

Can you get meaningful results from other I2C scanners on the DUE?

Looks like you did a good job!

Is it open source?  github code base or so?

Sorry,  but imho that is an faint echo of a datasheet. It has too little information to give any proper advice to get it working.

Is the Commodore 64  a uC or is it a computer with an OS ? (I don't know so I' asking)
Does it have more memory than an arduino ? Can it run Excel (I haven't seen anyone do that with an arduino.
The commodore 64 is an home computer based around 6502 uProc (1 Mhz, 64KB RAM). It had dedicated (powerful) chips for sound and video and IO. Although popular in games there was a complete office suite (word-processing spreadsheet etc)  Excel did not exist yet in those days but it had a ported version of visicalc (The mother of spreadsheets). Also other professional applications were written for the C64. It had also an expansion port with TTL level pins so you could extend it with your own electronics. Yes I have one in the loft collecting dust...

Hi Rude, did you manage to sort it out because I am a student and I have project to design and build attendance system and I am gathering information as much as I can and how can you help as well?
If you are a student you should try to design it yourself and show your work (project code) here.
If it doesn't work then you will get more help (but most people do not make your homework smiley-wink

Related to HourGlass function.

Does anyone know how long it takes for the millis function to rollover?
49 d, 17 h, 2 m, 47 s, and 297 millis .

one step further is to split the incoming stream in:
- the keywords looked for
- what is left ==> which can be input for a 2nd filter smiley-wink

Maar je moet wel heel goed nadenken over de interface.
Hou deze eenvoudig zodat ook beginners er snel mee aan de slag kunnen.

Wat voor lib wil je maken?
15  Using Arduino / Sensors / Re: Measuring distance between two devices? (<30m, as accurate as possible) on: April 22, 2014, 12:00:50 pm
Had a reply from the Pulsed LIght, LLC.

In brief, LIDAR-Lite can operate from 0-40m with cm resolution.  The overall accuracy is based on the reference clock which can either be internal to the programmable logic chip we use or an external source can be used.  The internal reference is advertised by Lattice as having a 5% accuracy and we use that number in our preliminary specifications for the LIDAR-Lite product.  Obviously, an external source would provide greater accuracy.  In testing of our prototypes the accuracy using the internal reference has generally run better than 1% and we expect that would hold true in our production sensors.  The rep rate is dynamically adjustable from 1-100Hz, although at the higher rep rates the range may be limited depending on the signal strength of the return signal.  

Communications is via I2C at either 3.3 or 5 VDC logic and the bit rate is 100Khz.  The unit operates as a slave and we are working on implementing user assignable addressing in the production sensors.  Implementing this feature in the programmable logic device is a bit more complicated than we had anticipated, so it isn't in any of the prototypes at the moment.  

I hope that I've addressed your questions.  We do plan on having more information available online as we move toward production.  If you have any additional questions, please feel free to contact me.
We are still testing the prototypes for real-world performance, which looks better than expected, so would only say that the specs may change as we release to production.

In addition to 3D Robotics writing code for their autopilot systems to support LIDAR-Lite, we also have a local Arduino group in Bend that is working on code for the Arduino micro controllers and will make that available along with other operating information as it is completed.

Please note that the information above is subject to change as it is a product in progress. Nevertheless it looks very promising!
If I get more information I will post it here.
