摘要:With the rapid technological enhancement , enormous no of electronic gadgets & devices are present in market. Each device is advance in a step of the earlier in technology.Our project "BLUETOOTH EMBEDDED PORTABLE OSCILLOSCOPE POWERED BY ANDROID" is more powerful tool towards to work of an distinct level more easy. Imagine how simple it would be to measure & display waveforms in our smart phone a simple touch¡¡¡ Portable oscilloscopes currently in the market are very costly, less efficient in power consumption and have displays with low resolutions . This paper illustrates & also implements low cost, portable, light-weight, power with low consumption, 2-mode channel oscilloscope, consisting of a hardware device and a software application. Proposed device is consist of Bluetooth module to provide wireless connectivity to a device with Bluetooth, running the Android operating system (OS), to visualize the respected waveforms. Android OS is choosen because in present there are around large number of users which uses Android device and many of them satisfy the basic features of the oscilloscope's. The hardware includ es circuitry to sense the input buffer voltage signals and an equipped Bluetooth module for transferring of sensed signal information to an Android operated device for visualize the waveforms. The Software application designed for Android receives the data transferred from the hardware and displays detected signal waveform according to the user configured display settings. These display screen configurations are passed to the hardware modules once they are reconfigured by the user, and hardware device uses to set the sampling rate and the values of samples. For minimum usage of the Bluetooth bandwidth, the application provides dual of operation, i.e. single channel mode where one of channel is operational and 2-mode channel where both channels 1 and 2 are in operation. The user is able to choose a mode from the GUI designed application, which in turn transfers a signals to the AVR microcontroller which then sets the frequency of sampling accordingly: a higher rate of sampling for single channel and half of that for dual channel.
