我最近在搞ch375模塊，我用的就是在貴站上下的源程序，用的文件是這三個(gè)CH375HFT.C，CH375HFB.H，CH375HFB.A，而且都按照貴站上的方法正確加載了，但我在ICC7.14上編譯時(shí)，總是出問(wèn)題，提示錯(cuò)誤若下： E:\PROGRA~1\ICC-AV~1\bin\imakew -f CH375.mak iccavr -o CH375 -g -e:0x20000 -ucrtatmega.o -bfunc_lit:0x8c.0x20000 -dram_end:0x10ff -bdata:0x100.0x10ff -dhwstk_size:30 -beeprom:0.4096 -fihx_coff -S2 @CH375.lk E:\avrdesign\ch375\CH375HFB.A -lcatm128 !ERROR file 'CH375HFB.o': undefined symbol 'push_gset1' !ERROR file 'CH375HFB.o': undefined symbol 'push_gset2' !ERROR file 'CH375HFB.o': undefined symbol 'push_gset3' !ERROR file 'CH375HFB.o': undefined symbol 'push_gset4' !ERROR file 'CH375HFB.o': undefined symbol 'push_gset5' !ERROR file 'CH375HFB.o': undefined symbol 'pop_gset1' !ERROR file 'CH375HFB.o': undefined symbol 'pop_gset2' !ERROR file 'CH375HFB.o': undefined symbol 'pop_gset3' !ERROR file 'CH375HFB.o': undefined symbol 'pop_gset4' !ERROR file 'CH375HFB.o': undefined symbol 'pop_gset5' !ERROR Function 'putchar' not defined.

可能是編譯器版本的原因，下載CH375LIB.ZIP，用\CH375LIB\AVR\FILELIBB_V7試試，這個(gè)庫(kù)的編譯器版本是7.13

哦，非常感謝！我試下。

還是不行啊，我編譯時(shí)還是一樣的錯(cuò)誤！隨后我下了個(gè)icc7.13的版本，編譯\CH375LIB\AVR\FILELIBB_V7，但還是不行，錯(cuò)誤提示如下： E:\PROGRA~1\ICC-AV~2\bin\imakew -f CH375.mak iccavr -o CH375 -g -e:0x20000 -ucrtatmega.o -bfunc_lit:0x8c.0x20000 -dram_end:0x10ff -bdata:0x100.0x10ff -dhwstk_size:30 -beeprom:0.4096 -fihx_coff -S2 @CH375.lk E:\avrdesign\ch375\CH375HFB.A -lcatmega !ERROR Function 'putchar' not defined.

E:\PROGRA~1\ICC-AV~2\bin\imakew.exe: Error code 1 Done: there are error(s). Exit code: 1. Wed May 20 09:50:54 2009 這到底是什么原因？真是郁悶！

這個(gè)是'putchar' 函數(shù)有問(wèn)題,你把我們例子程序里面的串口輸出即"printf"這個(gè)函數(shù)注釋掉看編譯可以不可以

非常感謝！激動(dòng)死我了，終于可以啦！而且我試了硬件，成功啦??！再次謝謝你們?。?！

但我還是想知道，這是什么原因??？自己試著改了幾下，都不行，不應(yīng)該啊，這應(yīng)該只是個(gè)輸出函數(shù)啊，怎么會(huì)有錯(cuò)誤呢？想不通。而且你們都編譯通過(guò)了，為什么我的就不行呢？都是7.13版本的，難道是因?yàn)槲疫@個(gè)是盜版的開(kāi)發(fā)環(huán)境？？

putchar是printf與串口之間的銜接接口，與編譯器有關(guān)，錯(cuò)誤提示不知道你理解沒(méi)有，這個(gè)函數(shù)ICC中沒(méi)有，需要自己根據(jù)硬件編寫(xiě)的

估計(jì)程序里面少鏈接了個(gè)頭文件,加上合適的頭文件就應(yīng)該可以了

我再按你們的方法試下，謝謝你們啦！

我按SCM的做法做了，果然可以啦！是自己加一個(gè)putchar函數(shù)就可以了。而且這個(gè)函數(shù)在ICC的examples.avr文件夾中有示例函數(shù)。 總算搞定了第一步了，以后還要繼續(xù)搞下去，研究更深層次的東西。在這里感謝所有幫助我的高手們，謝謝你們?。?！ 也希望本帖能給那些和我遇到一樣問(wèn)題，在痛苦中掙扎，但又一直堅(jiān)持不懈的戰(zhàn)友們一些幫助。同時(shí)，也希望以后能和大家有更多的交流。
