Source: https://blog.csdn.net/an520 UART, SPI, and I2C are very common serial communication methods in embedded development. The underlying principles of these communications are not difficult, but many beginners struggle to learn them. Today, I will share some common low-level data transmission principles of communication. UART Serial Port UART: Universal Asynchronous Receiver-Transmitter. UART is the most common … Read more
Abstract Chip programming is an important part of the production process of electronic products, and the efficiency of programming is a key concern for customers. The efficiency of programming is closely related to the programming speed of the chip. What factors influence the programming speed of chips? 1. Different Manufacturers’ Chips The differences between chip … Read more
Previously, we introduced how to make a logic analyzer and oscilloscope using RP2040. Today, we will build a logic analyzer using FPGA. Currently, the mainstream architecture of logic analyzers in China uses FPGA + USB PHY. The combination of the advantages of FPGA and the high accessibility of USB has allowed it to occupy the … Read more

1. Different Paths, Same Goal RS-232, RS-422, and RS-485 all belong to UART, which stands for Universal Asynchronous Receiver/Transmitter. They can complete communication using just two signal lines (Rx and Tx); However, due to the different voltage levels used by each, converting from UART to RS-232, RS-422, or RS-485 requires a conversion chip like the … Read more
