(3) 硬件上面没有 SPI 的单片机也可以控制本模块,用普通单片机 IO口模拟 SPI 不需要单片机真正的串口介入,只需要普通的单片机 IO 口就可以了,当然用串口也可以了。 NRF24L01无线模块的特点 低应用成本:NRF24L01集成了所有与RF协议相关的高速信号处理部分,比如:自动重发丢失数据包和自动产生应答信号等,NRF24L01的SPI接...

The AD5206 has 6 potentiometer channels. Each channel's pins are labeled A - connect this to voltage W - this is the pot's wiper, which changes when you set it B - connect this to ground. The AD5206 is SPI-compatible,and to command it, you send two bytes, ...

using, be sure to use another PWM capable pin. On most Arduino, the PWM pins are identified with a "~" sign, like ~3, ~5, ~6, ~9, ~10 and ~11. This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/Fade ...
Unset: clears pin designation. The pin is no longer reserved and can be automatically set at the next operation. Pins are configured on first usage. You can reset the pin mode to change the mode. If you want to use a pullup, you must set the mode to'pullup'. ...
