為了放心，我還是粗略的看了下它的規(guī)格書：

主要描述(除了內(nèi)核M23，其他外設(shè)幾乎沒啥變動)

當(dāng)前選用的C8T6(容量還是跟ST的保持一致，國產(chǎn)的就不能大些么~)

引導(dǎo)模式：

其中有一點(diǎn)不一樣的就是，它的BOOT1由原來的映射引腳，變成了寄存器的一個(gè)配置位！

我們用跳帽把BOOT0連到GND，選擇內(nèi)部FLASH啟動~
//////////////////////////////////////////////////////////////
我們看下我們最小系統(tǒng)的原理圖：

不能再簡陋了，就是最小系統(tǒng)加4個(gè)LED,2個(gè)KEY(其中只有WAKEUP能編程用)。
我們連接它的串口，好讓調(diào)試信息輸出：

查看數(shù)據(jù)手冊得：

還是PA9/PA10與ST的一樣。

我們打開GD32E23x_Demo_Suites_V1.0.1\GD32E230C_EVAL_Demo_Suites，這個(gè)板型號跟我的最新系統(tǒng)一致，就用它的程序進(jìn)行更改：

我們發(fā)現(xiàn)在它的gd32e230c_eval文件里，幾乎包含了我們想要的外設(shè)，但是引腳有少許差異，修改下：

編譯下載，查看現(xiàn)象：

按下WAKEUP鍵后，繼續(xù)執(zhí)行到WHILE里面：

?
LED輪流亮滅~

好了，就到這~
總體而言沒發(fā)現(xiàn)啥特別，上手也不難，庫寫的可讀寫也可以。
總而言之，國產(chǎn)MCU與國外的差距越來越小了~
