到了CORTEX-M4,幾乎每一快都有很大的知識量，單單GPIO庫文件這一項就有很長的章節(jié)要描述，加油吧
GPIO.h。是最基礎的一個庫文件，下面結合數(shù)據(jù)手冊來一一進行講解：
先把庫文件粘上，方便一一查閱：

以上是它的底層庫函數(shù)，也沒有什么復雜的東西，用以上的庫函數(shù)就可以進行編程了，按鍵和LED的例子就是用庫函數(shù)進行編程，下面我就結合數(shù)據(jù)手冊，利用寄存器來給M451進行配置；
NuMicro? NUC451 系列多達87個通用I/O管腳和其他功能管腳共享，這取決于芯片的配置。87個管腳分配在PA, PB, PC, PD, PE 和 PF六個端口上。PA, PB, PC, 和 PD最多有16個管腳，PE最多15個管腳，PF最多8個管腳。每個管腳都是獨立的，都有相應的寄存器位來控制管腳功能模式與數(shù)據(jù)。
I/O管腳的I狀態(tài)可由軟件獨立地配置為輸入，推挽式的輸出，開漏或準雙向模式。復位之后，所有管腳的模式取決于CIOIN (CONFIG0[10])的設置。每個I/O管腳有一個阻值為110K~300K的弱上拉電阻接到VDD 上，VDD范圍從5.0 V 到2.5 V。
6.6.2 特性
? 四種 I/O 模式:
? 準雙向模式
? 推挽輸出
? 開漏輸出
? 高阻態(tài)輸入
? 可選TTL/Schmitt 觸發(fā)輸入
? I/O可以配置為邊沿/電平觸發(fā)的中斷源
? 支持高驅動力及高翻轉速率的I/O模式。
? 通過CIOINI (CONFIG0[10])可配置所有I/O復位之后的默認模式。
? 如果CIOIN = 0, 復位后所有的GPIO管腳是準雙向模式
? 如果CIOIN = 1, 復位后所有的GPIO管腳是輸入模式
? I/O管腳僅在準雙向模式，內部上拉電阻才使能。
? 使能管腳中斷功能同時也使能了GPIO喚醒功能。
基本配置
GPIO管腳通過配置SYS_GPA_MFPL, SYS_GPA_MFPH, SYS_GPB_MFPL, SYS_GPB_MFPH,SYS_GPC_MFPL, SYS_GPC_MFPH, SYS_GPD_MFPL, SYS_GPD_MFPH, SYS_GPE_MFPL, SYS_GPE_MFPH 和SYS_GPF_MFPL寄存器來設定相應的功能
比如配置串口模塊的引腳
/* Set PD multi-function pins for UART0 RXD(PD.0) and TXD(PD.1) */ SYS->GPD_MFPL &= ~(SYS_GPD_MFPL_PD0MFP_Msk | SYS_GPD_MFPL_PD1MFP_Msk); SYS->GPD_MFPL |= (SYS_GPD_MFPL_PD0MFP_UART0_RXD | SYS_GPD_MFPL_PD1MFP_UART0_TXD);
功能描述
輸入模式
設置 MODEn (Px_MODE[2n+1:2n]) 為00, Px.n 管腳為輸入模式，I/O管腳為三態(tài)（高阻），沒有輸
出驅動能力。管腳 (Px_PIN
) 的值反映相應端口的狀態(tài)。
PD->MODE = (PD->MODE & (~GPIO_MODE_MODE7_Msk)) | (GPIO_MODE_INPUT << GPIO_MODE_MODE7_Pos);
推挽輸出模式
設置 MODEn (Px_MODE[2n+1:2n]) 為 01， Px.n 管腳為推挽輸出模式，I/O支持數(shù)字輸出功能，有
拉/灌電流能力。DOUT (Px_DOUT
) 相應位bit
的值被送到相應管腳上。
PB->MODE = (PB->MODE & (~GPIO_MODE_MODE3_Msk)) | (GPIO_MODE_OUTPUT << GPIO_MODE_MODE3_Pos);
開漏輸出模式
設置 MODEn (Px_MODE[2n+1:2n]) 為 10, Px.n 管腳為開漏模式且I/O管腳數(shù)字輸出功能僅支持灌
電流, 驅動到高電平需要一個外加上拉電阻。如果DOUT (Px_DOUT
) 相應位為‘0’, 管腳上輸出低.
如果DOUT (Px_DOUT
) 相應位為‘1’, 該管腳輸出為高阻，可以由外部上拉電阻控制。
PB->MODE = (PB->MODE & (~GPIO_MODE_MODE3_Msk)) | (GPIO_MODE_QUASI << GPIO_MODE_MODE3_Pos);
PD->MODE = (PD->MODE & (~GPIO_MODE_MODE7_Msk)) | (GPIO_MODE_QUASI << GPIO_MODE_MODE7_Pos);
設置MODEn (Px_MODE[2n+1:2n])為11，Px.n 管腳為準雙向模式，I/O同時支持數(shù)字輸出和輸入功
能，但拉電流能力僅達數(shù)百uA。要實現(xiàn)數(shù)字輸入，需要先將DOUT (Px_DOUT
)相應位置1。準雙
向輸出是80C51 及其派生產品常見的模式。若DOUT (Px_DOUT
)相應位bit
為‘0’ ，管腳上輸出
為“低”。若DOUT (Px_DOUT
)相應位bit
為‘1’，該管腳將檢測管腳值。若管腳值為高，沒有任何
動作，若管腳值為低，在該管腳上將有強輸出驅動2個時鐘周期的高電平，然后禁止強輸出驅動，
其后管腳狀態(tài)由內部上拉電阻控制。注意: 準雙向模式source電流的大小僅有200 uA到30 uA(相應
VDD的電壓從5.0 V到2.5 V) 。
GPIO中斷和喚醒功能
每個GPIO管腳都可以通過RHIEN (Px_INTEN[n+16])/FLIEN (Px_INTEN
)位和TYPE (Px_INTTYPE
)設置成芯片的中斷源。有五種中斷觸發(fā)條件可以設置：低電平觸發(fā)、高電平觸發(fā)、下降沿觸發(fā)和上升沿觸發(fā)以及上升與下降沿同時觸發(fā)。在邊沿觸發(fā)中用戶可以通過使能輸入信號去抖功能來阻止由噪聲引起的意外中斷。去抖時鐘源和采樣周期可以通過DBCLKSRC (GPIO_DBCTL[4]) 和DBCLKSEL (GPIO_DBCTL[3:0]) 寄存器來設置。
當芯片進入Idle/Power-down模式時，GPIO也可以喚醒系統(tǒng)。設置GPIO為喚醒觸發(fā)的條件與GPIO中斷觸發(fā)的條件相同。
/* Configure PB.2 as Input mode and enable interrupt by rising edge trigger */ PB->MODE = (PB->MODE & (~GPIO_MODE_MODE2_Msk)) | (GPIO_MODE_INPUT << GPIO_MODE_MODE2_Pos); PB->INTTYPE |= (GPIO_INTTYPE_EDGE << GPIO_INTTYPE_TYPE2_Pos); PB->INTEN |= GPIO_INTEN_RHIEN2_Msk; NVIC_EnableIRQ(GPB_IRQn); /* Configure PC.5 as Quasi-bidirection mode and enable interrupt by falling edge trigger */ PC->MODE = (PC->MODE & (~GPIO_MODE_MODE5_Msk)) | (GPIO_MODE_QUASI << GPIO_MODE_MODE5_Pos); PC->INTTYPE |= (GPIO_INTTYPE_EDGE << GPIO_INTTYPE_TYPE5_Pos); PC->INTEN |= GPIO_INTEN_FLIEN5_Msk; NVIC_EnableIRQ(GPC_IRQn); /* Enable interrupt de-bounce function and select de-bounce sampling cycle time is 1024 clocks of LIRC clock */ GPIO->DBCTL = (GPIO_DBCTL_ICLK_ON | GPIO_DBCTL_DBCLKSRC_LIRC | GPIO_DBCTL_DBCLKSEL_1024); PB->DBEN |= BIT2; PC->DBEN |= BIT5;

PB->MODE = (PB->MODE & (~GPIO_MODE_MODE2_Msk)) | (GPIO_MODE_INPUT << GPIO_MODE_MODE2_Pos);
設置PB2為輸入模式通過這個，你是否明白了？
void GPIO_SetMode(GPIO_T *port, uint32_t u32PinMask, uint32_t u32Mode)
{
uint32_t i;
for(i = 0; i < GPIO_PIN_MAX; i++)
{
if(u32PinMask & (1 << i))
{
port->MODE = (port->MODE & ~(0x3 << (i << 1))) | (u32Mode << (i << 1));
}
}
}
這個一一對應之后，之后的關于類似的問題都可以迎刃而解啦，哈哈
i為2 0X3<<(i<<1)=0X3<<0X4即0X3左移4位對照上文的宏定義對應GPIO_MODE_MODE2_Msk
#define GPIO_MODE_MODE2_Msk (0x3ul << GPIO_MODE_MODE2_Pos) /*!< GPIO_T::MODE: MODE2 Mask */
