A comparison of low-speed communication modes
Zhenhao Zhang · 2022
The low-speed fieldbus is wildly applied to communicate and manage between or even within sub-devices in smart equipment. The typical low-cost communication protocols I2C, SPI, and UART are still playing important roles in different industries. A comparative analysis of the three communication is introduced in this paper, while the fault-tolerant design methods of I2C and SPI are described in detail. The communication can be recovered automatically from the error once the recommended firmware solutions can be adopted. Different situations in real life may lead to the use of low-speed communication technologies.
