1. 转到终端并键入 sudo raspi-config。 2. 现在树莓派软件配置工具出现了。 3. 选择 接口选项 ,然后启用 I2C。 4. 启用 I2C 后重启 Pi。 使用树莓派扫描 PCF8591 的 I2C 地址 现在为了开始与 PCF8591 IC 通信,Raspberry Pi 必须知道它的 I2C 地址。要找到地址,首先将 PCF8591 的 SDA 和 SCL 引脚连接到...
Raspberry Pi Pico 如此有用的一个主要原因是其过多的硬件功能可以将处理器从执行常规 I/O 任务中解放出来。在我们的例子中,我们将使用 Pico 的直接内存访问 (DMA) 模块。这是一项硬件功能,可以自动执行涉及以极快的速度将大量数据传入和传出内存到 IO 的任务。 DMA 模块可以配置为一旦准备好就从 ADC 中提取...
我认为开源工具应该访问开源协议。 我使用此工具和 Raspberry PI 来刷写 EEPROM。 它还不能写入页面(因此您可以逐字节刷写、这需要更长的时间-大约2分钟)、但如果您像我一样进行原型设计、它就能完成工作。 https://www.richud.com/wiki/Rasberry_Pi_I2C_EEPROM_Program 我还尝试使用 Arduino...

ADC is a common accessory for Raspberry Pi. Nowadays many cheap MCUs has built-in ADC, so we make this 8-channel ADC based on STM32F030, which is a cost-effective, low-power ARM Cortex M0 MCU. We breakout 8 channels ADC from the MCU, and integrated 4 analog Grove connector so that...
In this tutorial, I go through the steps of setting up a Raspberry Pi ADC (Analog to digital converter). As you may already know the Raspberry Pi does not currently feature GPIO pins that are analog. This lack of analog pins makes connecting analog sensors a little more complex, as the ...

ADI 在其 ΔΣ ADC 教程中有一张经典的图,描述了调制器(ΔΣ MOD)、数字滤波器(Digital Filter)、数据编码(DEC)、输出数据速率(ODR,Output Data Rate)之间的关系,并且绘制了输入信号(In-Band Signal)与量化噪声(Quantization Noise)的频谱情况,我觉得不错,供你参考如下: ...
