Abstract
A data transmission system is provided. The data transmission system includes a serial peripheral interface (SPI) and a programmable controller. The SPI is coupled between a first device and at least one second device. The programmable controller controls the SPI to switch between a single port data transmission mode and a multi-port data transmission mode. When there are more than one second device coupled to the SPI, the SPI is switched to the multi-port data transmission mode so as to perform multi-port data transmission between the first device and the second devices. At this time, the first device concurrently transmits data to each of the second devices via a first transmission bus terminal, and concurrently receives data from each of the second devices via a second transmission bus terminal.
