System Design
Now that we have studied a range of system components, we can put them
together to form some typical MCU-based systems. A base module will be
designed which will be used for a range of different measurement and control
applications, a parallel memory expansion scheme outlined, and the range of
PIC microcontrollers and other processor families reviewed.
Base System
The base system can be used as a general purpose PIC board, and as the basis
for applications using the subsystems and interfaces described in the previous
chapters. A PIC 16F877 is provided with a keypad, alphanumeric display and
serial flash memory, with an RS232 serial link ...
