MSP430F5529PL外设功能封装（CCS和IAR都可用）

/**************************************************************************** * 方向设定寄存器 PxDIR 拉高设定为输出 拉低设定为输入(默认) * * 输入设定寄存器 PxIN 将引脚设定为输入 * * 输出设定寄存器 PxOUT 如果当前引脚已设定为输入方向，且上下拉电阻寄存器有效， * 则该寄存器可用来配置上拉和下拉电阻， * 低电平为下拉，高电平为上拉 * * 上下拉电阻寄存器 PxREN 低电平为无效，高电平为有效 * * * 功能选择寄存器 PxSEL 用来声明该端口是要应用于外围电路的特殊功能(不决定输入输出方向)，默认为低电平。 * 低电平表示普通的l/o（默认); * 高电平表示该引脚将有连接外围电路的特殊用途; * 如:开发板初始化函数HAL_Board.c中有这样一句程序:P5SEL|=（BIT2+BIT3）( =00001100); * 这句话的意思就是声明P5.2和 P5.3将有特殊用途，实际上这两个l/o接的是外部的高频时钟晶振（之后还要设定为输入状态才可以)。 * 此外需要注意的是，一旦某个l/o 的 PXSEL置高了，那么该引脚将不能再被用为中断引脚。 * * 输出驱动能力寄存器 PxDS 弱化驱动可以减弱电磁干扰EMl，全力驱动会增强电磁干扰。 * 默认为减弱驱动。 * 低电平表示减弱的驱动（默认); * 高电平表示全力的驱动; * ** 中断向量寄存器 PxIV 只有P1IV和P2IV对应端口P1和端口P2 具体引脚在中断服务函数中判断 * 如进入P1端口中断，后在服务函数中判断队友引脚哪个触发了 * * 中断标志寄存器 PxIFGx 对应中断使能 PxIE打开且总中断GIE打开，该寄存器才有效 * 低电平表示没有中断请求等待响应 * 高电平表示有中断请求等待响应 * * 中断使能寄存器 PxIE 低电平表示中断关闭 * 高电平表示中断允许 * * 中断使能寄存器 PxIES 低电平表示上升沿触发 * 低电平表示下降沿触发 * ****************************************************************************/ #include <MYGPIO.h> //************************************** // // // //************************************** void OUTPUT_GPIO_Config(unsigned int x,unsigned int y) { if( x == 1 ) { switch(y) { case 0: P1DIR |= BIT0; P1OUT |= BIT0; P1OUT &=~BIT0; break; case 1: P1DIR |= BIT1; P1OUT |= BIT1; P1OUT &=~BIT1; break; case 2: P1DIR |= BIT2; P1OUT |= BIT2; P1OUT &=~BIT2; break; case 3: P1DIR |= BIT3; P1OUT |= BIT3; P1OUT &=~BIT3; break; case 4: P1DIR |= BIT4; P1OUT |= BIT4; P1OUT &=~BIT4; break; case 5: P1DIR |= BIT5; P1OUT |= BIT5; P1OUT &=~BIT5; break; case 6: P1DIR |= BIT6; P1OUT |= BIT6; P1OUT &=~BIT6; break; case 7: P1DIR |= BIT7; P1OUT |= BIT7; P1OUT &=~BIT7; break; default: P1DIR = 0xff; P1OUT = 0x00; break; } } else if( x == 2 ) { switch(y) { case 0: P2DIR |= BIT0; P2OUT |= BIT0; P2OUT &=~BIT0; break; case 1: P2DIR |= BIT1; P2OUT |= BIT1; P2OUT &=~BIT1; break; case 2: P2DIR |= BIT2; P2OUT |= BIT2; P2OUT &=~BIT2; break; case 3: P2DIR |= BIT3; P2OUT |= BIT3; P2OUT &=~BIT3; break; case 4: P2DIR |= BIT4; P2OUT |= BIT4; P2OUT &=~BIT4; break; case 5: P2DIR |= BIT5; P2OUT |= BIT5; P2OUT &=~BIT5; break; case 6: P2DIR |= BIT6; P2OUT |= BIT6; P2OUT &=~BIT6; break; case 7: P2DIR |= BIT7; P2OUT |= BIT7; P2OUT &=~BIT7; break; default: P2DIR = 0xff; P2OUT = 0x00; break; } } else if( x == 3) { switch(y) { case 0: P3DIR |= BIT0; P3OUT |= BIT0; P3OUT &=~BIT0; break; case 1: P3DIR |= BIT1; P3OUT |= BIT1; P3OUT &=~BIT1; break; case 2: P3DIR |= BIT2; P3OUT |= BIT2; P3OUT &=~BIT2; break; case 3: P3DIR |= BIT3; P3OUT |= BIT3; P3OUT &=~BIT3; break; case 4: P3DIR |= BIT4; P3OUT |= BIT4; P3OUT &=~BIT4; break; case 5: P3DIR |= BIT5; P3OUT |= BIT5; P3OUT &=~BIT5; break; case 6: P3DIR |= BIT6; P3OUT |= BIT6; P3OUT &=~BIT6; break; case 7: P3DIR |= BIT7; P3OUT |= BIT7; P3OUT &=~BIT7; break; default: P3DIR = 0xff; P3OUT = 0x00; break; } } else if( x == 4) { switch(y) { case 0: P4DIR |= BIT0; P4OUT |= BIT0; P4OUT &=~BIT0; break; case 1: P4DIR |= BIT1; P4OUT |= BIT1; P4OUT &=~BIT1; break; case 2: P4DIR |= BIT2; P4OUT |= BIT2; P4OUT &=~BIT2; break; case 3: P4DIR |= BIT3; P4OUT |= BIT3; P4OUT &=~BIT3; break; case 4: P4DIR |= BIT4; P4OUT |= BIT4; P4OUT &=~BIT4; break; case 5: P4DIR |= BIT5; P4OUT |= BIT5; P4OUT &=~BIT5; break; case 6: P4DIR |= BIT6; P4OUT |= BIT6; P4OUT &=~BIT6; break; case 7: P4DIR |= BIT7; P4OUT |= BIT7; P4OUT &=~BIT7; break; default: P4DIR = 0xff; P4OUT = 0x00; break; } } else if( x == 5) { switch(y) { case 0: P5DIR |= BIT0; P5OUT |= BIT0; P5OUT &=~BIT0; break; case 1: P5DIR |= BIT1; P5OUT |= BIT1; P5OUT &=~BIT1; break; case 2: P5DIR |= BIT2; P5OUT |= BIT2; P5OUT &=~BIT2; break; c
