e00.asm		Before starting an assembly language program, we can begin with a template.
The e00.asm template reminds the basic settings required to write a program for the PIC16F887
experimental board. The '__CONFIG' directive is used to embed configuration data within asm file.
The internal oscillator circuit is used to generate the device clock (fosc = 4 MHz by default).
RA0, RA2, RA3 are configured as analog inputs; RC0/3, RA6 and RA7 will be used to control an LCD;
two LEDs are connected to RB4, RB5. RB6, RB7, RB3 are seserved for ICSP programming. 
RC6 and RC7 are used as the EUSART port.
Adding other parts requires configuring ports/registers properly.

e01a.asm	A blinking LED is the equivalent 'Hello world!' project for microcontrollers. 
This program blinks LED1 and LED2 alternately at a rate of about 1 Hz. Delays are generated by software loops.

e02a.asm	This program shows how to configure the EUSART module. A step-by-step guide can be
found in the datasheet of the PIC16F887. Hyperterminal must be configured for the desired COM port
at 9600 baud and 8N1 (data bits = 8, parity = none, stop bits = 1).

e02b.asm	With this experiment we evaluate a novel feature of the PIC16F887. This microcontroller supports
auto-baud detection. Once the calibration is finished, SPBRGH and SPBRG are loaded with proper values.
To appreciate this feature, try sending data at *any* baud rates (19200 baud max.). 

e02c.c		Serial communication with C (HI-TECH PICC LITE).

e03a.asm	With this experiment the state of LED1 and LED2 are changed each time a button is pressed.
The switch is polled and 'de-bounced'. Note that an internal pull-up resistor is used.

e03b.asm	Same as e03.asm, but each time the switch changes its state an interrupt occurs.

e04a.asm	An analog temperature sensor (LM335) is connected to RA0. We will give you an example experiment that samples the analog voltage 
with 8-bit resolution and sends the result via RS-232. 

e05a.asm	This is a basic program that initializes an hd44780-based LCD and writes a message.

e05b.asm	This programs shows the result of A/D conversions on the display.
