Introduction and Comparison of CAN, I2S, I2C, SPI, and SSP Buses

Introduction and Comparison of CAN, I2S, I2C, SPI, and SSP Buses

1. SPI Bus The Serial Peripheral Interface (SPI) bus technology is a synchronous serial interface introduced by Motorola. Most MCUs (Microcontrollers) produced by Motorola, such as the 68 series MCUs, are equipped with SPI hardware interfaces. SPI is used for full-duplex, synchronous serial communication between the CPU and various peripheral devices. It can simultaneously transmit … Read more

Understanding SPI, I2C, UART, I2S, GPIO, SDIO, and CAN: Can You Differentiate Them?

Understanding SPI, I2C, UART, I2S, GPIO, SDIO, and CAN: Can You Differentiate Them?

Buses, buses, you always get caught up in them. All signals in this world are the same, but there are thousands of buses, which can be quite a headache. In general, there are three types of buses: internal buses, system buses, and external buses. The internal bus connects various peripheral chips within the microcomputer to … Read more

Learning About I2S Bus: Concepts and Standards

Learning About I2S Bus: Concepts and Standards

Background The I2S bus is a common bus that needs to be mastered. Concepts The I2S (Inter-IC Sound) bus, also known as the integrated circuit built-in audio bus, is a bus standard formulated by Philips for audio data transmission between digital audio devices. This bus is responsible for data transmission between audio devices and is … Read more
