Serial PIC'n : PIC Microcontroller Serial Communications

Serial PIC'n details various methods for implementing serial communications between a Microchip PIC microcontroller and an external device. Asynchronous serial communications is covered both by using an on-chip USART and by bit-bang methods. The RS-232 standard is explained. A discussion of synchronous serial communications includes the I2C (Philips Semiconductors), SPI (Motorola) and Microwire (National Semiconductor) protocols. The Dallas Semiconductor 1-Wire bus is described. Many code examples are included as modules which will provide the basis for the reader's own PIC microcontroller applications.
