simplePIC.c, simplePIC_standalone.c, talkingPIC.c, NU32bootloaded.ld, NU32.c, NU32.h
Chapter 3 - Looking Under The Hood: Software
Problem 6: makefile (save as "makefile"; make sure there is no .txt extension)
Chapter 4 - Using Libraries
-> LCD code, has a bug
Chapter 5 - Time and Space
-> add a timing.c with coreTimer?
Chapter 6 - Interrupts
-> these are all plib, check all or change to registers, some plib fns did not work last year

OLD PIC32 Code
DIP PIC32 with reconfigurable pins (1/2xx) (11/21)
- Reconfiguring the pins.
Simple PIC
- simplePIC.c: Flashes LEDs on the NU32 unless the USER button is pressed.
NU32 library, header file, procdefs, and terminal comm test
- NU32.c: NU32 board library.
- NU32.h: NU32 header file.
- procdefs.ld: Linker file for NU32.
- NU32_serial_comm.c: Serial communication test with the terminal.
- NU32_serial_plot.c: Plot data with serial communication in NU32_Utility.
Interrupts
- INT_core_timer.c: Interrupt on core timer period match.
- INT_ext_int.c: Interrupt on rising edge of external interrupt line INT0.
- Peripheral timer interrupt.
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.
Counter/timer
- TMR_16bit.c: Set up a 16-bit timer to count the PBCLK.
- TMR_16bit_external_clocks.c: Count two external clock sources, such as the A and B channel from a motor encoder.
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.
Analog to digital (11/16)
- 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.
- Something else, scanning mode, asynchronous results check on the buffer, and/or interrupt generated when some results are ready.
Applications
DSP and FFT
- DSP_sample_square_wave.zip: Examples of FIR and FFT in both MATLAB and on the PIC32.
- DSP_mips32_fft.zip: Example of using the Q31 mips library for FFT. Contains a C source file and a header file.
Reading a quadrature encoder with the dsPIC33FJ12MC201 breakout board
- NU32_dsPIC_QEI_example.c: Read the encoder count at 250Hz, send to the computer at 5Hz
Controlling a stepper motor with the TB6612
- NU32_stepper_example.c: Use the TB6612 to step the motor at 25 Hz steps (1 rev in 16s)
Controlling an RC servo motor
- NU32_rcservo_pwm_example.c: Use a PWM pin to set the position of the servo (note you only have 5 PWM pins)
- NU32_rcservo_digio_example.c: Use any digital IO pin and a timer to set the position of the servo
