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.
