为NUC505读取字库并显示到19264做准备，尝试将字库下载到Flash AT45DB321中，本次用了M453，很顺手
上位机用了之前的编程器应用软件，稍作修改

做修改后的上位机软件

DS89C4x0_Programmer.zip (337.52 KB)

做字库的相关东东
测试用字库ziku_test.bin，字数只有前面的32个字
ziku.bin是正式的GBK字库

GBK字库制作软件.zip (1.31 MB)

对上位机的接收区和发送区进行了精简，超过200行进行清理，下载速度明显快了很多，对正式字库进行了下载，耗时90分钟左右
BIN文件总字节数744144，每包发送16个数据字节，共下发48384个数据包总包数 0xBD 0x00 包索引 0x00 0x00 ~ 0xBC 0xFF

并进行了抽样检查，字库存储正常，为NUC505的字库读取打下了基础
