Using a PIC32 to control brew pressure, steam pressure, and extraction time on a heat exchanger style espresso machine.

PIC32 Espresso Machine Controller

Fixed point filters using IIR second-order-sections (SOS) for good numerical stability. Matlab or Octave is used to factor the filters

Digital SOS filters for PIC32

The PIC32 programmable Vref generator can be used as a 4-bit DAC with a bandwidth of >200kHz. Good enough for speech playback.

The 2015 Hackaday Prize

Having been exclusive to a certain uC-line for over a decade, it's time to learn something new (and port commonCode!)... Enter MIPS

operation: Learn The MIPS (PIC32MX1xx/2xx/370)

PIC32 Charge-Time Measurement Unit is a programmable current source connected directly to an ADC pin.

Measure VERY short times plus R, L and C

The seed for the numbers comes from a floating ADC pin, whitened with the rand function. Needs further work for crypto.

Hook a 12-key matrix to a PIC32 and scan the keypad

Keypad matrix scanner for PIC32

Log-frequency spaced, digital bandpass filters updated at 8 KHz, averaged, and plotted on a LCD every 12 milliseconds. Suitable for speech.

Realtime Audio Filter-bank on PIC32

Two DDS units, one setting the phase of the other, with programmable envelopes make a FM synth unit.

FM sound synthesis on PIC32

Spectral speech estimate is stored in flash and reconstructed as a sum of sines during playback thru SPI attached DAC.

Speech playback on PIC32, 8:1 compression

TRS-80 Model I emulated on a PIC32MX processor; VGA, PS/2, and SD for tape and disk images. Oh, and glourious cassette sound.

TRS-80 Model 1 on a PIC32
