* \section Sec_Description Project Description:
|
|
*
|
|
* MIDI note synthesiser project. This project implements a basic DDS frequency synthesiser, capable of producing 8-bit PWM sine
|
|
* waves of variable frequency. When attached to a USB host, this project will allow for multiple MIDI notes to be synthesised into
|
|
* audiable sound via PWM, using the notes sent to MIDI channel 1.
|
|
*
|
|
* Outgoing audio will output in 8-bit PWM onto the timer 3 output compare channel A. Decouple the audio output with a capacitor
|
|
* and attach to a speaker to hear the audio.
|
|
*

|
* <td>Sets the maximum number of MIDI notes that can be generated simultaneously. More notes require more processing time,
|
|
* and thus a value that is too high will cause audiable sound distortion due to insufficient CPU time.</td>
