• sdram:- This basic application shows Shows how to initialize and perform read and write a SDRAM memory.

• spi:- Spi is configured in local loopback mode and uses SPI interrupt and DMA to store data from RDR reg of SPI to an input buffer

• ssc_dma_audio:- This example uses the Synchronous Serial Controller (SSC) of an SAMV7x micro-controller to output an audio stream through the on-board WM8904 CODEC. This example is fully functional

• tc_capture_waveform:- This example indicates how to use TC in capture mode to measure the pulse frequency and count the total pulse number of an external signal injected on TIOA pin.

• tcm:- This example indicates how to use TCM memories on SAMV7. It uses ITCm and DTCM memory for small code and data. and copies buffer using TCm memory and then compare with operations done using sram memory.

• trng:- The TRNG example shows how to generate random data with TRNG peripheral.

• twi_eeprom:- This example is fully functional and show how to uses twi with dma to transfer data to a flash memory.

• uart:- UART example uses polling mode, and runs in local loopback mode In another mode in example UART0 is sending and receiving characters using XDMA channel

• usart:- USART example uses DMA to transfer and receive buffer. In example it runs in loopback mode as well as in normal mode. In normal mode you board should be connected to D14 and D15 (Rx and Tx of USART0 on Samv7 Xplained board) end then it will echo the characters on the terminal. It shows the how Time-out functionality of USART can be used as well.

• usart_hw_handhsaking:- This example shows how to use RTS and CTS pin of USART. Connect the board to PC with appropriate USART and then send a file over terminal. This example will try to copy incoming buffer from PC to a local buffer using a ring buffer. and will raise CTS or RTS pin according to situation.

• usart_spi:- This example show how to use UART's SPI functionality to use it as a SPI.

• wdt:- This example shows how to use samv7x family micro-controller's watchdog interrupt. This example use WDT0.

• xdma:- In this example chunk of data store in memory transfers to another area using DMA.

• aes:- It encrypts and decrypts several test values in Electronic CodeBook (ECB) and Cipher Block Chaining (CBC),OBC,OFB,TRC modes and checks them against the known answers.

• icm:- The first one is used to hash a list of memory regions and save the digests to memory (ICM Hash Area). The second operation mode is an active monitoring of the memory.

• gmac:- Gmac example using lwip library is functional.

• gmac_lwip:- Gmac example using lwip library to show a small web-page. It is semi-functional.

• gmac_uip_helloworld:- Example using uip library and it is functional.

• gmac_uip_telnetd:- Example using uip library and it is functional. It show how we can use telenet functionality.

• gmac_uip_webserver:- Example using uip library and it is functional. It loads a small page on PC if Xplained board is connected to network.

• hsmci_multimedia_card:- This example uses HSMCI interface to show how to uses a mmc connected to the Xplained board.

• hsmci_sdcard:- This example uses HSMCI interface to show how to uses a sdcard connected to the Xplained board.

• hsmci_sdcard_fatfs:- This example uses HSMCI interface to show how to uses a sdcard connected to the Xplained board witha Fat file system to write and read the files on sdcard.

• hsmci_sdio:- This example uses HSMCI interface to show how to uses a sdio connected to the Xplained board.

• qspi_flash:- This example uses QSPI interface to show how to read/write a QSPI flash on board.

• usb_audio_looprec:- When an Xplained board running this program connected to a host (PC for example), with USB cable, the Xplained board appears as a desktop speaker for the host. Then the host can play sound through host software. The audio stream from the host is then sent to the Xplained board. At the same time, the audio stream received is also sent back to host from Xplained board for recording.

• usb_audio_speaker:- When an Xplained board running this program connected to a host (PC for example), with USB cable, the Xplained board appears as a desktop speaker for the host. Then the host can play sound through host software. The audio stream from the host is then sent to the Xplained board, and eventually sent to audio DAC connected to the amplifier.
