Does IIC support hot swapping? (With a detailed interpretation of CW32 IIC protocol) Have you learned it yet? After I finish these low-speed experiments, I will provide the debugging steps for the logic analyzer. IIC is done, next comes SPI, which is worth highlighting because the vast majority of devices use SPI; it’s practically ALL … Read more
01 【Introduction】 SPI: Serial Peripheral Interface, is a synchronous serial interface for device communication. SPI was developed by Motorola around 1985 and is 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 (MPUs). 02 【SPI Interface】 The SPI bus … Read more
1. Introduction UART, full name Universal Asynchronous Receiver/Transmitter, translated as Universal Asynchronous Transceiver. The emergence of serial ports was around 1980, with data transmission rates of 115kbps～ 230kbps. Initially, serial ports were used to connect computer peripherals, typically connecting mice, external Modems, and old cameras and graphics tablets. Serial ports can also be used for … Read more
