Introduction In the field of automation, there are devices that cannot be operated manually, such as high-pressure gates and corrosive liquid valves. Typically, we use computer software to control these devices through a combination of PC-based host software and a microcontroller. Project Requirements Design a controller with four relays that can be controlled via software … Read more
1. USB Fake U-Disk Experiment 1) Correctly download the hex file of the USB disk (fake U-Disk) to the microcontroller of the USB development board. 2) You will see a circular indicator for the fake U-Disk in the bottom right corner of your computer. 3) Open the circular U-Disk, and you will see a test … Read more

UART is an asynchronous full-duplex serial communication protocol consisting of two data lines, Tx and Rx. Since there is no reference clock signal, both parties in communication must agree on serial baud rate, data bit width, parity bit, stop bit, and other configuration parameters to communicate at the same rate. Asynchronous communication transmits one character … Read more

Clickthe blue textto follow us at FPGA Home – the best and largest pure FPGA engineer community in China SPI Bus SPI (Serial Peripheral Interface) is a high-speed, full-duplex, synchronous, serial communication bus that uses 3 to 4 lines and operates in a master-slave mode, … Read more
Enhancing anti-interference is one reason. Standard UART can choose 16x sampling or 64x sampling; I personally think it should be for convenient frequency division design. The RXD front end of the standard UART has a “1 to 0 transition detector.” When it continuously receives 8 ground level signals on RXD, the detector considers that the … Read more

UART, I2C, SPI are the most commonly used serial communication protocols. Today, I will share some insights into the underlying communication protocols. (Source: 8号线攻城狮)
Introduction In serial communication applications, we often use receive and transmit interrupts, which most of you are familiar with. There is a very useful interrupt that may be overlooked, which is the bus IDLE interrupt. When a frame of data transmission ends, the bus will maintain a high level state, at which point the MCU’s … Read more
