I2S x1

红外收发器：5个发射通道，5个接收通道

1 个 12 位 SAR ADC，带 7 个通道

DMA 控制器，具有 3 个接收通道和 3 个发射通道

1.2. 接口

1.3. 原理图

1.4. BMP180传感器模块

需要个人采购哦，可以从淘宝购买。

1.5. 显示模块0.96 128X64

可以在立创购买。

1.6. 硬件连接：

基于IIC进行连接。由于杜邦线连接不可靠，这里基于面包板进行连接。

1.7. IO使用

GND，3.3V，SDA，SCL。

2. 软件开发

采用arduino平台

2.1. 库安装

2.2. 代码实现

2.3. 编译和上传：

2.4. 串口数据接收

2.5. 验证效果：
