I have collected several MP3 schematics, including ALIM5661X (commonly known as Ali solution)/Actions ATJ2055/ATJ2091/ATJ2135/SUNLINE SPDA1000/Rising Micro 2608A. Friends who need it can take a look. ...
The transplanted u-boot used by hl340 to usb has garbled characters, but there is no garbled characters when directly connected to the serial port. Does hl340 not support uboot? Please tell me clearly...
This article shares some basic concepts in FPGA design (such as setup time, hold time, race conditions, triggers, latches) and some design methods (such as synchronization design, delay circuit design...
Many people are familiar with smart bracelets. Although the functions of bracelets from different manufacturers vary, at their core, they all rely on various sensors. Understanding the sensors will he...
This peripheral is an AD9516 clock chip, which can output different clocks through FPGA. Now I have only implemented the SPI interface based on FPGA, but how can I initiate read and write operations o...
