ds32c35是dalas生产的实时时钟（RTC）芯片，本程序（在EP2C8Q208C8N上调试通过）在FPGA上构建I2C接口于此时钟芯片通信。可以在LED上动态实时显示时间。利用本程序也可以改编成高精度实时时间测量的程序-ds32c35 is produced by dalas real-time clock (RTC) chip, this program (in the EP2C8Q208C8N debugging via) in the FPGA built this clock ch

interface Pic18F4550 with IC RTC DS1307 by modul I2C.

NUC1xx 的 I2C总线挂接RTC芯片PCF8563，本例程通过I2C外设读写PCF8563、启动PCF8563片内时钟和闹钟。-NUC1xx I2C bus articulated RTC chip PCF8563, the routine through the the I2C peripheral read and write PCF8563, start PCF8563 chip clock and alarm clock.

RTC 3231 Driver. It is tested and completely work. I2c is its interface!
