Use in application C-file: //Buffer to send data to SPI slave. //Buffer to receive data from SPI slave. //Select given device on the SPI bus. //Wait for the transmitter to be ready. // Send the data to slave (ie = AT45DBX_CMDC_RD_STATUS_REG) //Wait for a complete transmission. //Wait for the transmitter to be ready.
AVR ATmega16 uses three registers to configure SPI communication that are SPI Control Register, SPI This bit gets set when SPI data register write occur during previous data transfer. Make MOSI, SCK and SS pins directions as output.

Covers all AVR Microcontrollers with In-System Programming support wire SPI interface, the In-System Programmer communicates serially with When Reset is applied to the target AVR microcontroller, the MISO pin is set up For details on available instructions, refer to the Serial Programming section of the datasheet.
#include void SPI_MasterInit(void); void SPI_MasterTransmit(char cData); void SPI_MasterInit(void) { /* Set MOSI and SCK output, all others
What are the data directions of the SPI pins? It depends on the particular pin and on whether the SPI is set as a Master or Slave. In general, there are two
AVR is a family of microcontrollerss developed since 1996 by Atmel, acquired by Microchip The AVR instruction set is more orthogonal than those of most eight-bit microcontrollers As long as the SPI pins of the AVR are not connected to anything disruptive, the AVR chip can stay soldered on a PCB while reprogramming.Most of the AVR provide a SPI interface which enables a connection with a serial Entering the interrupt handler with the state variable set to INSTRUCTION
To ease and accelerate SPI serial memory integration with AVR devices, to write data, the write enable latch must be set by issuing the WREN instruction.
