基于C8051F330的24c04测试程序 利用I2C接口直接对其读写-24c04 based on the C8051F330 the test procedure using I2C interface to read and write directly

这是点阵程序 个人认为先学点阵再学lcd比较好 p0 p2分别接16*16点阵的高八位和低八位(纵向取模) p3口低四位接4-16线译码器（74ls154）译码器低电平为列选 消除鬼影的方法：-This is the program individual lattice lattice before you think lcd is better to learn p0 p2, respectively, then 16* 16 lattice of high and low 8 8 (vertical modulus) p3 I received a low four 4-16 Line Decoder browser (74ls154) low-level decoder for the elimination of ghosting out the election approaches:
