View source for ME333 Sample Code

'''Simple PIC'''

* [[Media:simplePIC.c|simplePIC.c]]: Flashes LEDs on the NU32 unless the USER button is pressed.

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

* [[Media:NU32.c|NU32.c]]: NU32 board library.
* [[Media:NU32.h|NU32.h]]: NU32 header file.
* [[Media:procdefs.ld|procdefs.ld]]:  Linker file for NU32.
* [[Media:NU32_serial_comm.c|NU32_serial_comm.c]]:  Serial communication test with the terminal.
* [[Media:NU32_serial_plot.c|NU32_serial_plot.c]]:  Plot data with serial communication in NU32_Utility.

'''Analog to digital'''

* [[Media:ADC_Read2.c|ADC_Read2.c]]:  Reads two analog inputs repetitively and prints the results to the user's terminal.
* [[Media:ADC_Read2_LCD.c|ADC_Read2_LCD.c]]  Reads two analog inputs repetitively and prints the results to the LCD.

'''Digital I/O'''

* [[Media:DIGIO_sfrs.c|DIGIO_sfrs.c]]:  Digital I/O and change notification using SFR manipulation.
* [[Media:DIGI0_plib.c|DIGIO_plib.c]]: Digital I/O and change notification using the peripheral library.

'''Interrupts'''

* [[Media:INT_core_timer.c|INT_core_timer.c]]:  Interrupt on core timer period match.
* [[Media:INT_ext_int.c|INT_ext_int.c]]:  Interrupt on rising edge of external interrupt line INT0. 

'''LCD code'''

* [[Media:LCD.c|LCD.c]]:  LCD library.
