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

Welcome FPGA engineers to join the official WeChat technical group. 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
Click on the above “Electronic Engineer’s Notes” and select “Pin/Star the Official Account” Valuable content delivered instantly! UART (Universal Asynchronous Receiver/Transmitter) is an asynchronous full-duplex serial communication protocol consisting of two data lines, Tx and Rx. Since there is no reference clock signal, both communication parties must agree on serial baud rate, data bit width, … 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
How to Understand Clock Phase (CPHA) and Clock Polarity (CPOL) in SPI Programming? I2C Operation Notes – Taking AT24C04 as an Example Still Don’t Understand Serial Communication? This Article Will Help You Understand
Introduction In serial communication, we often use receive and transmit interrupts, which everyone is familiar with. There is another very useful interrupt that may be overlooked, namely the bus idle state IDLE interrupt. When a frame of data transmission ends, the bus remains high idle, which triggers the MCU’s IDLE interrupt. In this article, we … Read more
