LIST OF FILES  
*************


Main files for this project:
---------------------------------------------------------------------------------------------------
mtr_dac2.asm	Source code for PIC16F84. Metronome software for the version published in Elektor,
                using a discrete D/A converter based on a 74HC574.
mtr_dac2.hex    Binary code
mtr_dac2.lst    listing
p16f84x.inc	Include file defining names of registers and other items.


Auxiliary files used to create mtr_dac2.asm:
---------------------------------------------------------------------------------------------------

PHASETBL.C	Source code of C program to create the table of phase increments (ptbl.inc).
PHASETBL.EXE	Executable of previous file (MS-DOS)
ptbl.inc	File generated by executing PHASETBL.EXE: Table of phase increments to generate 
                the different frequencies of the notes.

SINETBL.C	Source code of C program to create the table of amplitudes to generate a sinewave.
SINETBL.EXE	Executable of previous file (MS-DOS)
stbl.inc	Generated by SINETBL.EXE. Table of amplitudes to generate a sinewave.
	

Other files (not necessary for this project):
---------------------------------------------------------------------------------------------------

mtr_piezo.asm	Source code for PIC16F84. Metronome software for a simpler metronome version using
                a piezo sounder instead of a DAC and an amplifier.
mtrzn428.asm    Source code for PIC16F84. Metronome software for a different version of the
                published metronome using an integrated circuit DAC model ZN428 from Ferranti.
lcd4bit.asm     Test program for LCD 4-bits interface routines. Also, this file can be used as an
                skeleton to develop an application using an LCD display module.


	

OPTIONS FOR ASSEMBLING THE PIC SOURCE CODE FILES
************************************************
Default radix is decimal


OPTIONS FOR PROGRAMMING THE PIC
*******************************

The PIC should be programmed with the following options:
 - Code Protection OFF
 - Power-Up Timer enabled
 - Watch Dog Timer not enabled 
 - XT crystal oscillator (100Khz-4MHz)

A CONFIG directive is included in the source code to define these options.
