// Timer interrupt experiment

// To model sine wave I send 12 bit integers to DAC8512 
// Each integer corresponds to the current sine point
// (from 0 mV to 4095 mV)

// Data is transferred over SPI, so there actually
// may be a performance issue, considering the speed
// at which I want to output values 
// (dt = 5 µs between two consecutive points)
