* * \section SSec_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. * * \section SSec_Options Project Options * * The following defines can be found in this project, which can control the project behaviour when defined, or changed in value. * * * * * * * * * * * * *
Define Name:Location:Description:
MAX_SIMULTANEOUS_NOTESMIDIToneGenerator.hSets 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.
