SPI (serial peripheral interface) using AVR microcontroller (ATmega16)

Leave a Comment / Using Atmega / Tech Master

There are different protocols for serial communication between two deceives like, USART, SPI, I2C etc. Before selecting any communication protocol, data transfer rate is an important parameter. SPI transfers data at high speed data. AVR microcontroller contains on chip SPI interface. This article will explore the hardware configuration and programming of SPI. Serial Peripheral Interface is a synchronous, full-duplex protocol. […]
