Serial Ports

I2C control of ISD voice chip.

This project implements I2C to control a Winbond/ISD voice IC.

PS/2 Interface.

Provides an example of using a UART for PS/2 communications.

PS/2 Interface.

Shows how to build a PS/2 interface.

RS-232 and SIM card example

This project uses UARTs for both RS-232 communications and to communicate to a standard SIM card.

RS-232 port

This project provides a good example of how to setup and use the M16C's UART with RS-232.

RS-232 setup example.

Project provides a good example of setting up and using a UART with an RS_232 connection.

Serial Port example

This battery powered application uses the serial port to communication with a simple wireless link as well as an RS-232 host.

Serial port using DMA.

Project provides an example of using a serial port witha DMA channel.

SPI and I2C interface example.

Project contains code for setting up both an SPI and an I2C interface. Good for talking to external EEPROMs and other devices.

SPI talks to MMC and SD cards.

This project uses a LUA software port. Within this port is code for a FAT file system using SPI to communicate with MMC/SD cards.

SPI using DataFlash

Project provides an example of connecting and using external SPI based DataFlash.
