raspberry pi pico 红外接收

Raspberry Pi Pico是树莓派基金会推出的一款微型电脑开发板，它搭载了ARM处理器和用于编程的MicroPython环境，可以广泛应用于物联网和嵌入式系统等领域。

红外接收是Pico的一个功能模块，通过该模块可以实现对红外信号的接收和解码操作。红外接收器可以接收由红外发射器发送的红外编码信号，然后通过Pico的GPIO引脚进行连接和读取。

在使用Pico的红外接收功能之前，我们需要先通过编程设置GPIO引脚的模式为输入模式，然后使用相应的库函数对红外接收器进行初始化。

一般我们会使用RP2(IPCORE)-IR库，该库提供了红外接收功能的API接口。使用该库，我们可以轻松地配置和使用红外接收器，并通过调用库函数来获取红外编码信号的数据。

例如，我们可以通过IR.decode()函数来读取红外编码信号，然后对读取到的信号进行进一步的解码和处理。

另外，为了更好地使用红外接收功能，我们可以使用红外遥控器来发送红外编码信号进行测试和验证。可以通过Pico的GPIO引脚连接红外发射器，然后编写程序发送红外编码信号进行测试。

总之，Raspberry Pi Pico的红外接收功能为我们提供了便捷的方式来接收和解码红外编码信号，可以广泛应用于遥控器、红外传感器等领域。通过编程和硬件连接，我们可以实现更多有趣的功能和应用。
