单片机 FM25256
使用模拟方法 读写 fm25256 sbit lcdrs = P2^2; //寄存器选择，H：数据，L：命令 sbit lcdrw = P2^1; //H：读 L：写 sbit lcdcs = P2^0; //片选 sbit fmcs1=P3^4; //EPROM片选U32 sbit fmcs2=P3^5; //EPROM片选U33 sbit fmsio=P3^6; //EPROM信号 sbit fmsck=P3^7; //EPROM时钟 const uint wren = 0x06; //set write enable latch const uint wrdi = 0x08; //write disable const uint rdsr = 0x05; //read status register const uint wrsr = 0x01; //write status register const uint read = 0x03; //read memory data const uint write = 0x02; //write memory data
