Xilinx‘s JTAG cable can directly program SPI/BPI. Many users who are not familiar with the Xilinx development environment may have questions when encountering this programming mode for the first time. How does the FPGA bridge between JTAG and Flash? Is there a dedicated circuit inside the FPGA to achieve this function? Actually, no. The FPGA … Read more
Communication between electronic devices is like communication between humans; both parties need to speak the same language. In electronic products, these languages are called communication protocols. Previously, articles on SPI, UART, and I2C communication were shared separately. This article compares them. Serial vs Parallel Electronic devices communicate by sending data bits to each other. A … Read more

1. UART: The Lightness of Qiu Qianzhang’s Skills In “The Legend of the Condor Heroes”, Qiu Qianzhang says, “UART is like my lightness skill, floating over the water to cross the river.” To cross the river (communication), one must prepare in advance, setting markers at fixed intervals (baud rate predetermined). If the steps are too … Read more
