國產(chǎn)替代環(huán)境下，測試了下GD32E230C8T6最小系統(tǒng)板
[導(dǎo)讀]基于ST的對(duì)應(yīng)型號(hào)缺貨，大家都紛紛測試國內(nèi)的替代芯片，我也想試一把?？吹紾D32E230C8T6理論上可以替代STM32F103C8T6，在這次去X商城買料的時(shí)候，我順便買了片樣片，并要了個(gè)免費(fèi)的最新系統(tǒng)樣板PCB。到貨后，馬不停蹄開工，焊好。焊好后，去官網(wǎng)下載資料：（資料下載請(qǐng)...
基于ST的對(duì)應(yīng)型號(hào)缺貨，大家都紛紛測試國內(nèi)的替代芯片，我也想試一把。看到GD32E230C8T6理論上可以替代STM32F103C8T6，在這次去X商城買料的時(shí)候，我順便買了片樣片，并要了個(gè)免費(fèi)的最新系統(tǒng)樣板PCB。
到貨后，馬不停蹄開工，焊好。
焊好后，去官網(wǎng)下載資料：（資料下載請(qǐng)點(diǎn)擊閱讀原文內(nèi)下載）
MDK PACK:?
規(guī)格書：?
用戶手冊(cè)：?
固件手冊(cè)：?
BSP:?
對(duì)應(yīng)開發(fā)板資料：?
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(dòng))
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(dòng)~
//////////////////////////////////////////////////////////////
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(cè)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(hào)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：

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~
