This forced me to write about more interesting and comprehensive sorting methods, the RESULT of which is this one. Through this writing I have tried to give in-depth coverage of the entire sort algorithm I hope Peter wouldn t mind reading it. This article assumes that you really don t know about the iterations, looping, and so forth hence, it explains these in detail first.

// This program measures the voltage on an external ADC input and prints the // RESULT to a terminal window via the UART. // // The system is clocked using the internal 24.5MHz oscillator. // RESULTs are printed to the UART from a loop with the rate set by a delay // based on Timer 2. This loop periodically reads the ADC value from a global // variable, RESULT.
