This
experiment was based on getting input of various sensors using ADC and display
the output on DSO using DAC. Digital-to-Analog converters (DACs) and
Analog-to-Digital converters (ADC) are important building blocks which
interface sensors (e.g. temperature, pressure, light, sound, cruising speed of
a car) to digital systems such as microcontrollers or PCs. An ADC takes an
analog signal and converts it into a binary one, while a DAC converts a binary
signal into an analog value. Applications for DACs span a wide range, from
consumer audio to precision instrumentation, and everything in between. A DAC
produces a set of analog values that corresponds to the digital input codes.
Many DAC designs are actually current output devices, instead of voltage output
devices.
Great, that's the advantage of Digital Signal Processor that it allows sensor interfacing!
ReplyDeleteGreat that you were able to interface so many sensors using one small board!
ReplyDeleteTotal of 6 sensors were present on the board.
ReplyDeleteJTAG cable was used to interface DSP processor and the computer rather than USBASP cable as JTAG allowed the user to check the values of the register of DSP processor in intermediate stages rather than just at the end which helps in debugging.
ReplyDeleteADC DAC was used in this experiment!
