# 1 Harmony 3 Driver and System Service Application Examples for SAMA7G5 Family

The following applications are provided to demonstrate the typical or interesting usage models of one or more drivers, system services and RTOS.

Name | Description
--- | ---
FAT Filesystem using SDMMC Media | This application shows an example of using the MPLAB Harmony File System to access and modify the contents of a SD card using the SDMMC driver
FreeRTOS Basic | This example application demonstrates context switching between four tasks of different priorities. Two tasks run periodically while the other two tasks are event driven
I2C Driver Asynchronous - I2C EEPROM | This example application shows how to use the I2C driver in asynchronous mode to perform operations on the EEPROM
I2C Driver Synchronous - I2C EEPROM | This example application shows how to use the I2C driver in synchronous mode to perform operations on the EEPROM
I2C EEPROM AT24 Driver - EEPROM Read Write | This example application shows how to use the AT24 driver to perform read and write operations on AT24 series of EEPROM
SPI Driver Asynchronous - Multi Client | This example demonstrates how to use single instance of the SPI driver in asynchronous mode to communicate with multiple EEPROMs
SPI Driver Synchronous - Multi Client | This example demonstrates how to use single instance of the SPI driver in synchronous mode to communicate with multiple EEPROMs in an RTOS environment
SPI EEPROM AT25 Driver - EEPROM Read Write | This example application shows how to use the AT25 driver to perform read and write operations on AT25 series of EEPROM
Time System Service Multi-client | This example application demonstrates the multi-client system timer functionality
USART Driver Asynchronous - USART Echo | This example echoes the received characters over the console using the USART driver in asynchronous mode
USART Driver Synchronous - USART Echo | This example echoes the received characters over the console using the USART driver in synchronous mode
