I2C协议是在开发中使用非常频繁的一种协议,相信大家在学习单片机的时候经常会用到支持I2C协议的模块,I2C 总线仅仅使用 SCL、SDA 这两根信号线就实现了设备之间的数据交互,极大地简化了对硬件资源和 PCB 板布线空间的占用。因此,I2C 总线被非常广泛地应用 ...
Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
据非官方统计,90%电子行业的公众号都介绍过3种串行通讯协议:UART、SPI和I2C。这3种串行协议也是电子开发行业最常用的协议。前面介绍了串口通讯协议及其FPGA实现,SPI协议。本篇文章介绍I2C通讯协议及其FPGA实测波形。 文末有【I2C官方标准文档下载方法】。
I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the sheer variety ...
You only really need two data wires to transfer a ton of data. Standards like UART, USB2, I2C, SPI, PS/2, CAN, RS232, SWD (an interface to program MCUs), RS485, DMX, and many others, all are a ...
