我使用的是AT89C51單片機(jī)，使用KEIL軟件，按照置頂?shù)姆椒虞d了CH375HF4.LIB文件，如圖，第一個(gè)編譯當(dāng)前文件時(shí)，0錯(cuò)0警告，第二個(gè)build target時(shí)，就不行了，如下。。

倒底怎么回事呀？

參考這個(gè)例程：UploadImages/2009568182651.rar

另外AT89C51資源是不夠的,要求代碼空間不小于12K,RAM不小于700個(gè)字節(jié),必要資源必須保證.

你把編譯的單片機(jī)型號(hào)選擇成AT89C52就可以編譯了,但是要是燒到單片機(jī)里面去的話要按照3樓所說(shuō)的來(lái)選擇單片機(jī)咯.

謝謝上面三位的回答。。。。

我想問一下，能不能推薦我一個(gè)合適的而且市面上常見的51單片機(jī)，謝謝啦。

51單片機(jī)最普通了，常用的很多，如NXP，ATMEL、SST等等，如SST89E54RD 具體型號(hào)可以去官網(wǎng)查詢

謝謝六樓回復(fù)，我的意思是，對(duì)CH375完全合適的單片機(jī)，現(xiàn)在真不知道用哪款好了。。。

選型主要考慮以下幾個(gè)方面： （1）CH375的接口：并口或串口 （2）子程序庫(kù)需要的資源：1OK以上程序空間，最少600字節(jié)的RAM 滿足上述2個(gè)條件單片機(jī)都可以

太謝謝了
