Embedded Design with the PIC18F452 Microcontroller written by John Peatman (Prentice Hall, 2003) in support of Microchip Technology’s PIC18F family of microcontrollers.
The QwikFlash devlopment board is used as an example in the book for interfacing the PIC18F452 to various external components. The board contains varous I/O devices such as an RS-232 port (for program code development with QwikBug), RPG, potentiometer,a pushbutton, an LCD, and a few LEDs.
Shown above – QwikFlash board chained to a QwikProto board which has been equipped with a magnetic card reader, a stepper motor, and a temperature sensor having a PWM output.
A temperature sensor is included on the board to demonstrate the use of the PIC18F452’s A/D module. A two-channel D/A converter illustrates the use of the PIC18F452’s SPI three-wire interface.
