👇Click to follow for daily technical insights!👇 1 Introduction SPI: Serial Peripheral Interface, a serial peripheral interface. SPI was developed by Motorola around 1985 and is a synchronous serial interface suitable for short-distance, device-to-device communication. Since then, this interface has become a de facto standard adopted by many semiconductor manufacturers, especially microcontrollers (MCUs) and microprocessors … Read more

First, a little aside~ It is said online that the IIC of STM32F103 has flaws! Let’s just consider it as some shortcomings; personally, I think it can definitely be used, but it is not easy to use. Because ST Company considered patent issues, they did not follow Philips’s standards. This leads to the IIC of … Read more
1. Why Use Serdes Traditional source-synchronous transmission separates clock and data. There are no issues at lower rates (<1000M). As the rates increase, this becomes problematic Due to inconsistent delay and jitter in transmission lines, the receiver cannot sample data correctly, resulting in misaligned eye diagrams. This leads to the idea of recovering the … Read more
