An embodiment (not shown) that is intended to simply read and recognize information is provided with a storage oscilloscope for displaying waveform of signals processed by the signal processing portion 50. Information is written, for example, line by line into a memory in synchronized mode using a...
Again, I looked at my data lines in the oscilloscope MOSI:0x30 | 0x20| 0x6C | 0x0 | 0x0 (Sends 3 byte address one dummy byte(per display datasheet), and one dummy byte to move last read byte in rx buffer MISO: 0x0 | 0x4A | 0x43 | 0x42| 0x01 (first 4 bytes are bogus ...
You use thefscanffunction to read ASCII data from the instrument. For example, the oscilloscope command'Display:Contrast?'returns the oscilloscope's display contrast: fprintf(v, 'Display:Contrast?'); data = fscanf(v) data = 45 fscanfblocks until one of the following occurs: The EOI line is ...
The oscilloscope trace below shows what an I2C communication with the monitor looks like on the wire. The top line (cyan) shows the clock. Note that the clock only runs while data is transmitted.) The yellow line is the binary data. At the bottom, the oscilloscope decoded the data (green...
tuned to the frequency fr, i.e., when the difference fr-fxis equal to zero, the frequency meter 13 will read zero. For initial tuning, the signal at frequency focould be compared with the signal at frequency fron an oscilloscope, but it is only necessary to tune for a zero meter ...
The fact that this cannot seemingly be done without getting into looping through an array of controls, assigning the control to a general control variable etc. and much more guff is puzzling and is in my opinion an added complexity to Visual Basic. There must be a simple way to do this ...

Then I remembered the dropouts I initially saw on the oscilloscope. Maybe these dropouts aren't actually dust or scratches, but the DVD player too fast to and then jumping back on the disc to maintain the correct data rate on average? To find out if that's the case, I captured another...
This blog post will show you how to use your Analog Discovery 2 to verify what the signal looks like from an Arduino PWM pin in LabVIEW. To do this we will use a LabVIEW VI, called LabForms, which allows you to connect anAnalog Discovery 2USB Oscilloscope to LabVIEW. The LabVIEW code...
Oscilloscope Reading Device for the Visually Impaired The purpose of this paper is to describe an assistive technology solution to the problem of allowing visually impaired individuals to use an oscilloscope in an electronics laboratory setting. More specific, a stylus device was implemente... D Kamp...
