Introduction - If you have any usage issues, please Google them yourself
This program outputs sine and cosine waveforms using the hardware DACs
// on the C8051F06x microcontroller. The waveforms are output on pins DAC0
// and DAC1.
//
// The output of the DAC is updated upon a Timer4 interrupt. The Timer4 ISR
// then calculates the output of the DACs for the next interrupt.
//
// The frequency of the output waveforms is set by the#define <FREQUENCY>.
// To achieve the exact output frequency defined by <FREQUENCY>, an
// external crystal should be used.
