写CH375B的程序可以用CH375A的子程序库吗？

可以使用CH351A的子程序库，不过建议你把库升级下，这样U盘的兼容性会更高

目前CH.75A已经停止供货，建议申请CH375B做实验。

我们单位原来用CH375A，现在改用CH375B了，我在一款产品上座调试，加入CH375模块，不过老出现问题，一调用CH375DiskReady( );程序就飞了，前面的 CH375Reset( ); Delay(10); i = CH375LibInit( ); /* 初始化CH375程序库和CH375芯片,操作成功返回0 */ mStopIfError( i ); 和while ( CH375DiskStatus < DISK_CONNECT ) { // 查询CH375中断并更新中断状态,等待U盘插入 CH375DiskConnect( ); Delay(10); } 都通过了，到那就飞了，不知道跑到哪去了，好像有时会重新从头开始运行程序

1、更新库后，程序编译、链接是否正常? 2、LibInit，DiskConnect都成功？

单片机的RAM有没有溢出，用的是什么单片机？RAM，ROM各式多少？
