SENSOR INTERFACING


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.

  1. Great, that's the advantage of Digital Signal Processor that it allows sensor interfacing!

  2. Great that you were able to interface so many sensors using one small board!

  3. Total of 6 sensors were present on the board.

  4. JTAG 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.
