Have you ever wanted to filter noise on an incoming analog signal? Would you like your system to notify you when an analog signal goes above, below, inside or outside of a defined window? If so, then this video will explain how to use the Analog-to-Digital Converter with Computation or ADCC to average a noisy signal from an incoming sensor. This video will also show how to use the ADCC threshold comparison to give an interrupt any time the input signal falls outside of a certain window.
The video demonstrates how easy it is to add capacitive sensing into an application using core independent intelligent analog features and the MPLAB® Xpress Development Platform. Burst Averaging capabilities of the Analog-to-Digital Converter with Computation (ADCC) are used to read the voltage level based on the capacitance of a sensor made with conductive ink. The 10-bit ADCC value will be transmitted over the serial port to a computer running a terminal program. The ADCC value will register a higher value when the sensor is alone and a lower value when an object such as a finger touch is introduced.
Have you ever wondered how to use the window comparator on the ADC in Atmel START? Or have you ever wondered how you can use the accumulation on the ADC to filter analog readings? Have you ever wondered simply how to set up the ADC peripheral in START? Well this tutorial will answer these questions and more such as how to set up the advanced ADC, using the window comparator to generate interrupts, and filtering analog readings. By the end of this tutorial, you should have a better understanding of how the analog to digital converter is configured and you should also understand some of the advanced capabilities available on the analog to digital converter in Atmel START.

Do you need to filter a noisy incoming signal? Have you ever wondered how to set up the low pass filter on a PIC micro controller? This video tutorial will explain how to configure and use the low pass filter on the ADCC peripheral to modify a square wave as well as filter periodic noise from a DC signal.
