In C language

Write the playnote( ) function for the lab. Recall the function takes a struct note as its only argument. AssumeTOGGLESPEAKER, delaycycles(), mydelayms() and the frequency array are already set up.

struct note { unsigned char notenum; // index into array of frequencies for this note unsigned char duration; // duration of note in 1/8ths of a second };

const unsigned int frequency[] = { // note number & note 262, // 0 C 277, // 1 C# etc, etc, etc };
