The design of Atmega32 MCU SPI and MAX191 serial A/D communication

Wei Zhang

Abstract

A/D converter and digital signal as an analog signal interface circuit, the data processing has a very important role, A/D converter and microcontroller interface design directly affects the A/D conversion rate and conversion accuracy. To improve the accuracy of ADC conversion, to speed up the pace of research, presented Atmega32 SPI MCU interface and design, and provides software programming, the MAX191 through the SPI interface to communicate with the microcontroller, to achieve real-time processing of data.
