| Abstract: | A high accuracy A/D conversion electric circuit is designed, based on synchronous SPI serial bus interface. The synchronous serial communication is achieved by programming in MCU register or simulated time output in I/O interface. This technique meets the demand of complicated electric circuit system design with multiple SPI serial bus interface, which has high value of engineering application. |
