“Serial Communications”  is a comprehensive advanced level book which 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. By Roger Stevens (8-1/2 x 11 format, 566 pages, $49.95).
