sudo i2cdetect –y 1 或 sudo i2cdetect –y 0 现在找到 I2C 地址后,是时候构建电路并安装必要的库了,以便将 PCF8591 与 Raspberry Pi 一起使用。 将PCF8591 ADC/DAC 模块与 Raspberry Pi 连接 PCF8591与树莓派接口的电路图很简单。在这个接口示例中,我们将从任何模拟引脚读取模拟值并将其显示在 Raspberry Pi...
2. ADC 采样代码 我的麦克风测试台 如果您还没有这样做,我强烈建议您在 GitHub 上克隆 Raspberry Pi 的pico-examples库。这是我开始使用的所有采样代码的地方。以下代码的很大一部分来自此存储库中的 dma_capture 示例。 我将通过我的软件的一些关键元素来解释发生了什么。您可以在代码部分找到完整的程序。
Step 1. Plug the 8-Channel 12-Bit ADC for Raspberry Pi (STM32F030) into Raspberry Pi. Step 2. Connect the Grove - Sound Sensor to A0 port of the ADC module. Step 3. Connect the Raspberry Pi to PC through USB cable. Hardware connection diagramTap...
