Design of UART communication based on FPGA/CPLD device and high-level language VB

introduction With the development and wide application of computer technology, especially in the field of industrial control, the application of computer communication is particularly important. Although serial communication greatly reduces the connection between devices, it brings problems such as serial/parallel conversion and bit counting, which makes serial communication technology more complicated than parallel communication technology.

UART adaptive top-down design based on FPGA device

UART (Universal Asynchronous Receiver Receiver) is a widely used serial data transfer protocol. The UART allows full-duplex communication over the serial link. Dedicated UART integrated circuits such as 8250, 8251, NS16450, etc. are already quite complex, and some contain many auxiliary modules (such as FIF0). In practical applications, only a few basic functions of UART […]

Have you mastered the advanced usage of Arduino serial port?

Configure serial communication data bits, parity bits, stop bits Usually we use Serial.begin(speed) to complete the initialization of the serial port. In this way, only the baud rate of the serial port can be configured. And use Serial.begin (speed, config) to configure data bits, parity bits, stop bits, etc. For example, Serial.begin (9600, SERIAL_8E2) sets […]
