Imagine a signal coming from your microphone. Now let's take a moment to remember what the time domain, looks like. Luckily, it turns out that we can approximate our function with some finite number k sines and cosines and that each time we increase k, the approximation becomes more accurate. You may be worried about that word 'infinite' up there. Square waves, sawtooths, Bart Simpson's hair any arbitrary waveform can be represented by a simple sum of sines and cosines. Give that a minute to sink in any function that is continuous - not differentiable, just continuous - and periodic - but the length of the period can be as long as you like - will do. The central nugget of the matter goes like this: any continuous, periodic function can be represented as an infinite sum of sines and cosines. (Prerequisites note: If you don't have a firm understanding of the concepts frequency, wavelength, and sinusoidal graphs, it's time for a trip to wikipedia.

To write software that can do that, we must have a firm understanding of the frequency domain. In order to recieve information, the computer must be able not just to record the sounds coming from the pen, but to analyze them. My path is clear: create a livescribe modem! Most computer owners have a microphone on hand and communicating via tones is a tried and true method. No, there must be a better way so we turn to the speaker. Besides, special hardware would be necessary, and that would make the potential user base tiny: linux-using livescribe owners who have the knowledge and hardware to program microcontrollers. While this is plausible, the narrow bandwidth of the light produced by the OLED display makes it difficult to sense - and the communication would always be one way. My original plan had been to use light sensors, an AVR, and a program that would flash the pen's OLED display in order to send data back to the desktop computer. I concentrated instead on the other two ways the pen has of communicating: the screen and the speaker. While reverse engineering the livescribe communications protocol would have been the correct way to do it, I feared it was, and is, beyond my means and motivation.

Since I was first able to program my livescribe pulse (in a rude rendition of 'hello, world'), I've been scheming on how to communicate with the pen through hackish means.

Even through virtualization of a windows machine, you'll be lucky to get a working system.Īnother is the fact that, while programs build with the livescribe pre-release SDK can save files to the pen, they cannot send those files to the desktop machine - the only way to interact with program data is through the pen. it hasen't been dropped so I am not sure what to do.One of the frustrating things about the exciting livescribe pulse is it's inability to communicate with linux. I have not used the pen awhile and my screen is black.

Sorry your email accidentally went to junk. You want to download, install, and use the utility.įollow us on Twitter! By Service Email (Werner Langer) ( 07:42 PM) If a hard reset does not resolve you issue, please try updating your smartpen using the firmware flash utility. Your smartpen will restart with the message “livescribe… Starting…” KEEP HOLDING THE POWER BUTTON UNTIL THE SMARTPEN TURNS OFF. Your pen will restart in a recording session. Press and hold the power button for 10+ seconds. We recommend that in order for you to try to resolve the display issue with your smartpen, please hard reset your smartpen (this will not affect the data on your smartpen). To update your question with additional information, please reply to this email. Here is one of the replies I received:Below is a summary of your request and our response.
