51单片机-240128液晶程序与调试

今天终于把金鹏OCMJ8X15D-2液晶（240128点阵带字库无触屏液晶）调好了。这块液晶能显示8行15个汉字，还有放大字形，从16*16点放大到32*32点的功能。对于觉得12864的4行8列内容过少，或者觉得0.5*0.5mm的点的大小过于粗糙的情况来说，这款液晶是很适合的，它的点大小为0.33*0.33mm。

可能是习惯了12864这样的液晶，结果在硬件连接上就出来了一个重大错误，结果弄了好久也只显示条形点阵，而且对比度很差。这个错误就是240128液晶的对比度调节电位器，两端一端接地，另一端接VOUT（22脚）！而我习惯性的接到了5V！在曹老师的提醒下才发现了这个问题，在手册的角落里发现了硬件连接图：

最后附上调试好的程序：
