在不断发展的电子元件领域,继电器——作为切换电路的关键设备,正在经历前所未有的技术变革。固态继电器(SSR)和机械继电器之间的争论由来已久。然而,从未来发展的角度来看,固态继电器正逐渐占据上风。本文将从耐用性、速度和能效三个方面,全面 ...
the Raspberry Pi 4 has six SPI controllers, six I2C controllers, and six UARTs – all on its 40-pin header. You can’t make use of all of these at once, but with up to four different connections ...
I2C (Inter-Integrated Circuit): 一种同步多主多从串行通信协议 ... 误差累积:长时间传输可能出现同步误差。 应用场景: UART、RS-232。 同步通信适用于需要高效、高速数据传输的场景,但通常需要额外的硬件支持。 异步通信适合简单低速应用,易于实现和调试。
To the average microcontroller, Ethernet networks are quite a step up from the basic I2C, SPI and UART interfaces, requiring either a built-in Ethernet MAC or SPI-based MAC, with tedious ...
