7、RAM(Character Generator RAM)。下图(如图12)说明了CGROM和CGRAM与字符的对应关系。从ROM和RAM的名字我们也可以知道,ROM是早已固化在LCD1602模块中的,只能读取;而RAM是可读写的。也就是说,如果只需要在屏幕上显示已存在于CGROM中的字符,那么只须在DDRAM中写入它的字符代码就可以了;但如果要显示CGROM中没有的字符...

在命令或数据的判定bit变为“0”时,下一个byte数据就是显示数据。在变为显示数据的输入状态时, 命令就不能输入了。在需要再次输入命令时,必须再次形成开始条件。 1.3显示数据的写入与传送方法 本芯片内置了36×4=144bit的显示数据RAM(DDRAM)。 显示数据和写入数据的对应关系以及DDRAM数据和地址和显示的对应关系如...
