Simple PIC

  • simplePIC.c: Flashes LEDs on the NU32 unless the USER button is pressed.

NU32 library, header file, procdefs, and terminal comm test

Analog to digital

  • ADC_Read2.c: Reads two analog inputs repetitively and prints the results to the user's terminal.
  • ADC_Read2_LCD.c Reads two analog inputs repetitively and prints the results to the LCD.

Digital I/O

  • DIGIO_sfrs.c: Digital I/O and change notification using SFR manipulation.
  • DIGIO_plib.c: Digital I/O and change notification using the peripheral library.

Interrupts

LCD code

Output compare (PWM)

  • OC_PWM_nolib.c: Set up PWM by setting SFRs.
  • OC_PWM_lib.c: Set up PWM using peripheral library functions.
  • OC_square_wave.c: Alternate between two different PWM duty cycles at 1 Hz. PWM is at 100 kHz and can be low-pass filtered to get a square wave analog output.

Counter/timer

DSP and FFT

Reading a quadrature encoder with the dsPIC33FJ12MC201 breakout board

Controlling a stepper motor with the TB6612

Controlling an RC servo motor
