1、处理器与外部设备通信的两种方式： 串行通信有两种通信方式： 并行通信： -传输原理：数据各个位同时传输。 串行通信方式有 UART USB IIC SPI CAN 以太网等都是采用串行通信方式。 数据按位顺序传输。 允许数据同时在两个方向上传输，因此，全双工通信是 ...

我一直在做单片机开发，不知道Linux是怎么一种调试方式。 对于单片机开发来说，不管是UART、I2C、SPI、USART，比起像STlink之类的在线硬件仿真调试，都是弟弟。 以前我也是用比较Low的办法，去调试程序的BUG，比如借助数码管，屏、UART，甚至是LED灯，因为有些 ...

Have you ever used the term UART only to be corrected by another engineer that it isn’t a UART but USART? In certain circumstances the interchangeability of these ...

One of the most basic and also most versatile communication interfaces on an MCU is the UART, or Universal Asynchronous Receiver/Transmitter. Usually found in the form of either a UART or USART, the ...

We find it interesting that PIC and AVR programming is very common in hobby electronics but ARM doesn’t have nearly the same foothold. This is partly because there’s a knowledge barrier involved with ...
