SPI Programming with Atmega 8/16/32 Basic SPI Program, Master and Single Slave communication Simple SPI Coding Serial Peripheral Interface I tried treating eeprom as a character file in C, but the obtained data are incoherent (I did a test in bare-metal code and the SPI device works), maybe because I don't know how data has to be send, Could somebody explain me with a piece of code, how should I read/write to SPI EEPROM?. To fix this, we need to explicitly switch pins PA5-PA7 to the SPI mode. Compared to some peripheral devices like sensors, which can only run in slave mode, the SPI of the AVR can be configured for both master and slave mode. Refer to the AVR910 application note for details. Every device will share the “SDI”, “SDO” and “Clock” pins, but each device will have it’s own chip select pin (also known as slave select).
