A.4
RS-232 Serial Port
An RS-232 level shifting IC has been provided with all necessary hardware to
support connection of an RS-232 host through the DB9 connector. The port is
configured as DCE, and can be connected to a PC using a straight through
cable.
The PIC16C74 has its RX and TX pins tied to the RX and TX lines of the
MAX232A.
A.5
Switches
Three switches provide the following functions:
S1 - MCLR to hard reset the processor
S2 - Active low switch connected to RA4
S3 - CCP1 for capture of timer
Switches S1 and S3 have debounce capacitors whereas S2 does not,
allowing the user to investigate debounce techniques.
When pressed, the switches are grounded. When idle, they are pulled high
(+5V).
A.6
Oscillator Options
RC oscillator (2MHz approximately) supplied. This oscillator may be
disabled by removing jumper J7.
Pads provided for user furnished crystal and two capacitors.
Socket provided for clock oscillator.
Provisions are also provided for an external crystal oscillator for Timer1.
A.7
Analog Input
A 5K ohm potentiometer is connected through a series 470 ohm resistor to
AN0.
The pot can be adjusted from V
DD
to GND to provide an analog input to the
parts with an A/D module.
