完成前面3步就完成了UART的基本配置,接下来就可以进行收发了, 使用uart write bytes()往Tx FIFO buffer里面写数据,就可以发送数据; 使用uart read bytes()从Rx FIFO buffer里读数据,就是接收数据; 其他的工作由FSM(UART controller’s finite state machine)完成 。 具体的使用可以查看手册上面Running UART Commun...
Serial communication is simplya way to transfer data. The data will be sent sequentially, one bit at a time (1 byte = 8 bits), contrary to parallel communication, where many bits are sent at the same time. UART protocol More specifically, when you use Serial with Arduino and Raspberry Pi...
To start a UART communication in your ESP32 code, you need to specify the UART port, baud rate, and pin mapping. Here’s an example of initializing UART communication with a GPS module—this can be applied to other modules or devices. /*** Rui Santos & Sara Santos - Random Nerd Tutor...

Because of the serial/UART layer and the fact that the HM-10 has limited custom characteristics, I will be using a single characteristic for all data. This means using the HM-10 is not really using BLE as it was intended. If I were do the same thing using a different chip or module...
串口通信(Serial Communication), 是指外设和计算机间,通过数据信号线 、地线、控制线等,按位进行传输数据的一种通讯方式。 UART UART全称为Universal Asynchronous Receiver/Transmitter,通用异步收发传输器。UART一般用于电路板内部通信或者短距离通信,最常用的就是单片机,stm32等。UART通信是两个IC(integrated circuit)进...
The function takes a single parameter: the desired communication speed. You must use the same speed for the sending side and the receiving side, or you will see gobbledygook (or nothing at all) on the screen. This example and most of the others in this book use a speed of 9,600 baud...
