IIC静默模式下读取数据

来源：互联网发布：淘宝店铺分为几种类型编辑：程序博客网时间：2024/06/05 15:21

说明：

这个文件只是个头文件，是用于IIC静默模式下，读取所有IIC数据，然后通过串口转发用于显示。

还必须配合IIC_Recv.lib文件才能使用，有兴趣的话可以联系提供该LIB文件。

提供了详细的调用说明。

IIC静默模式：类似于IIC从模式，但是不过滤地址，不返回ACK，按字节接收所有数据，并转发到串口。

//1.定義SCL,SDA,INT
#define PA4_SDA GPIO_Pin_4
#define PA5_INT GPIO_Pin_5
#define PA6_SCL GPIO_Pin_6
//---以下三個宏定義需要根據不同的硬件來修改，但是名字不能修改

#define Read_INTGPIO_ReadInputDataBit(GPIOA, PA5_INT)
#define Read_SCLGPIO_ReadInputDataBit(GPIOA, PA6_SCL)
//---注意：Read_SDA、Read_INT、Read_SCL爲關鍵字，不能改變，否則出錯！！！！

//2.三個引脚都必須定義爲IPU，根據硬件修改

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;

//3.必須使能INT中斷，上下邊沿，根據硬件修改
GPIO_EXTILineConfig(GPIO_PortSourceGPIOA, GPIO_PinSource5);

1.每次触摸最少三个数据，与触摸屏接触时间越长，则发出的数据越多；
2.触摸弹起：坐标全为0；
3.各类手势：发出手势经过的X,Y坐标点；
4.所有帧间隔：32ms;
5.忽略ACK/NAK.
