3 identical shifted signals, 5 Khz, tunnable by program, with sensors

[luisji]

Hello

I'm looking for the easiest way of using PSoC5 to make a:

* 3 identical squared signals, shifted 120 degrees (It could change to be a SPWM sinus signal, but for now, a PWM could be enough)

* About 5 KHz, 20% tunnable by program, (depending on an audible feedbak captured with a microphone)

* Able to read 3 I2c, 2 ADC with low resolution, the audio, and act as programmed

* Handling an LCD Display

* With an interruptions clock to know each round of program if tasks, as the LCD, are ready, instead of being waiting for their answer to can continue attending the generation of signals

My real problem has been to know  how to generate this 3 signals, so If solving the generation of them, the rest can go further easily.
