本源码是模拟软核51利用I2c控制SRAM进行读写控制的程序

用ARM芯片GPIO模拟I2C程序，能在51或ARM使用,GPIO with ARM chip I2C simulation procedures can be used in 51 or ARM

/* 51系列单片机在使用时，有时需要模拟I2C总线， */ /* 这里举出一个实例（读写串行EEPROM芯片at2402） */-/* 51 Series single-chip, when used, is sometimes necessary to simulate I2C bus,*//* here to cite a concrete example (read and write serial EEPROM chip at2402)* /

51端口模拟T2C协议编程，使用时可直接调用，程序已对外部使用函数做了外部声明，所有函数可直接调用！-51 port simulation T2C agreement programming, use can be called directly, procedures have to external use function to make the external statement, all functions can be called directly!
