謝謝大俠，問題解決了

我在編譯msp430f149讀U盤出現(xiàn)下面提示是什么原因我用的是IAR4.11 Building configuration: demo - Debug Updating build tree...

這2個警告可以不關(guān)心，不影響使用

謝謝樓主，確實不影響使用，我從網(wǎng)站上下載的ch375讀CP2102程序，里面有"HAL.H""HAL_BASE.C"在那能找到

CH374EVT.ZIP,到在線下載里面去搜索就可以了.

請問大俠ch374的 * 寄存器及緩沖區(qū) */

對CH375不適用，CH374/5兩者的內(nèi)部結(jié)構(gòu)是完全不同的，CH374是通過訪問寄存器的方式，而375是命令驅(qū)動方式。

謝謝樓主，請問有沒有ch375做主機控制cp2012通訊的相關(guān)例程，可供參考

http://wch.cn/bbs/View.asp?S=101&I=19463 這個鏈接上有CH374操作CP2102的例程，可以參考一下

樓主你好，請您給看一下這段程序里面 UINT8 CP2102_Start_stop( UINT16 Value )//Value=0X0000-->Stop,Value=0x0001-->Start { Buffer[0]=0x41;Buffer[1]=0x00;Buffer[2]=(UINT8)(Value&0xff);Buffer[3]=(UINT8)((Value>>8)&0xff); Buffer[4]=0x00;Buffer[5]=0x00;Buffer[6]=0x00;Buffer[7]=0x00; return ( HostCtrlTransfer375( Buffer, NULL, NULL ) ); } 的 41 00 01 00 00 00 00 00 是什么意思，有沒有關(guān)于端點命令的資料可以參考一下，謝謝

這個你沒有必要詳細(xì)追問,你直接移植就可以了. 41 00 01 00 00 00 00 00 沒有什么意思,就是CP2102自己定義的一個命令,關(guān)于這些操作你不必關(guān)心,這些是經(jīng)過我們數(shù)據(jù)分析看出來的.這個資料估計是不公開的,我們也沒有.

請問：我在ICC6.31A下可以編譯，而在ICC7.14C下不能編譯，如何解決

編譯器版本不兼容，要更換不同的庫，我們有ICCAVR_7.13@AVR 的庫，你可以試試．

這個庫在哪里能找到 ICCAVR_7.13@AVR

網(wǎng)上下載CH375LIB.ZIP或CH374LIB.ZIP，AVR/LIBB_V7
