用于ATmega128的一些通讯程序，包含I2C　UART，SPI等接口，用ICCAVR编译-for ATmega128 some communications procedures, including UART I2C, SPI interfaces with ICCAVR compiler

SD卡和AIC23数字音频输出实验, FreeDev Audio Dsp Board采用了TI公司的TVL320AIC23 1、控制接口使用I2C，Quartus中将CS置低（器件地址0011010）。 2、数字音频接口使用了组件FreeDev_aic23,有三种测试和应用 模式，中断结合DMA方式能在NIOS II中采集和发送数据。中断信号 产生于模块中FIFO缓冲区的半满信号，读取数据端口自动清除中断 请求信号。 3、I2C IP 和FreeDev_aic23 IP分别在Quartus 工程目录中 4、SD卡读写通过SD_DAT0、SD_CLK、SD_CMD三个PIO信号线用软件 控制时序。 5、该范例读SD卡数据，通过DMA将Buffer数据送到FreeDev_aic23的 FIFO中实现数据播放。 6、SD卡中的数据必须是以48K*16bit保存的采样数据。数据可以通过SD读卡器写入。

通过W5200芯片连接网络，实现DHCP，DNS，UDP，TCP通讯，W5200内部自带TCP协议栈，通过SPI接口连接单片机，此代码单片机为STM32F103 VBT6，可同时实现8个SOCKET

Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface. PIC Modbus RTU slave supports write and read (3 and 16) functions. The data is stored and read from EEPROM via the I2C bus. You can write/read up to 8000 registers. In a single frame can be read/write 32 registers . The program was written in the HI-TECH C compiler-Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface.
