Audio_Power_Amplifier_With_Spectrum_Display 项目介绍 使用STM32的内部ADC对音频信号进行采样,再通过FFT形成频率和幅值对应的函数,显示在由单总线控制的8 * 10的RGB LED阵列上 首次更新 2017.6.23 使用STM32内部12位的ADC对有直流偏置电压的音频信号进行采样,采样点为1024。 对1024个采样点进行FFT处理,这里使用的是ST官方FFT库,输出不同频率对应的电压幅值。 对频率进行分组,按照指数增益分为十个组。对电压幅值进行分组,分为八组。十组频率八组电压值形成二维数组。 采用一根信号线控制首尾相连的8×10的WS2812 RGB LED阵列,每颗LED有24bit颜色深度,为了方便程序编写,这里只编写了全灭在内的25种不同亮度的不同颜色。 将二维数组显示在8×10的WS2812 RGB LED阵列上,电压越高颜色

Relevant time durations for modern science range from the femtosecond of very fast electronics to the age of the universe, 15 billion years. This corresponds to a range of about 32 orders of magnitude. Moreover, this variable can be controlled and measured with an accuracy better than 10−14 by modern atomic clocks. However, the accuracy that can be obtained by purely electronic circuits, such as integrated circuits, is only of the order of 10−3. This is because there is no combination of available electronic components (like a RC time constant for example) that is more precise and constant with time and temperature. Now, 10−3 corresponds to an error of about 1.5 minute per day, which is totally unacceptable for timekeeping applications. The same is true for applications to modern telecommunications, which exploits the frequency spectrum up to 300Ghz.
