A frequency counter is a test instrument that measures frequency accurately. You can find its application in many radio frequency (RF), to measure the frequency of repetitive signals. These days, digital frequecy counters ahve made their ways to various circuitry. The basic working principle of ...
if (set_frequency_hz == 1 && set_frequency_khz == 0 && set_frequency_mhz == 0 ) { / / 检查是否按下了以Hz为单位设置频率的按钮 moduleFrequency = counter; //更新模块频率变量与当前计数器值 } if (set_frequency_hz == 0 && set_frequency_khz == 1 && set_frequency_mhz == 0 ) {...
像RF这样的无线解决方案可以将数据发送到远距离，但需要更多的电力才能进行电池操作，而另一方面BLE可以用...
选择“ClockGenerator1”并在属性窗口中将“Frequency”设置为 5 <<这将是更改颜色的速度,您可以根据需要更改频率 选择“Counter1”并在属性窗口中将“Max”>“Value”设置为 40,将“Min”>“Value”设置为 0 双击“NeoPixels1”并在“Pixel Groups”窗口中将“Color Pixel”窗口拖到左侧,然后在属性窗口中将“Cou...
Believe me, you need NOT any expensive RF equipment on finishing this project although it is a U/V band one. It would be helpful if you have SWR meter, frequency counter, CTCSS analyzer or spectrum analyzer on hand. I am to discuss with few of them in the "further thoughts steps". ...
虽然Arduino 基板设计的早期迭代只利用 Atmel 8、16 和 32 位 AVR 微控制器,但最近却出现了许多包括非 Atmel MCU 和 MPU 在内的基板。 在适当考虑一些重要设计取舍后,这不仅可向设计师赋予更大的处理器与 I/O 灵活性,还可提供更多选择,让 Arduino 板运用于从开发到生产的所有阶段。

While some MCUs include a WiFi and/or Bluetooth transmitter, I could not find a mainstream MCU with a sub 1 GHz transmitter. On the other hand there are several boards available that combine one of the MCUs listed with a separate RF chip. ...
RF tool based on CC1101 module and Arduino Pro Micro 8VMHz/3.3V. Allows using CLI with human readable commands to control CC1101 board over USB interface. Putty or any other serial terminal can be used. It has similar functionality to YardStick One but i
