Same way you'd interface anything with anything else:

Documentation for the SAM V71 Xplained Ultra Evaluation Kit is here:

your question is too vague to be able to give any samples.

 

have you actually tried searching yourself?

 

There must be literally thousands of examples of people who've connected GPS units to microcontrollers

As for WiFi, the board has an Ethernet connection - so just connect that straight to your WiFi access point ...

But how would handling a GPS device on a SAMV71 be any different from handling a GPS device on any other platform?

 

The GPS device neither knows nor cares what microcontroller you're using - it's behaviour does not change when you use a different "host" !

 

Similarly for WiFi.

which one is good for SAMV71 ATMEL studio or KEIL?

Both will be fine.

 

http://www.keil.com/appnotes/docs/apnt_274.asp

 

Keil will not give you the ASF Wizard stuff.

Atmel Studio will automatically recognise an XPlained-Pro board, and will present you with its list of ready-to-go examples specifically written for that board.

Usually, a WiFi access point just connects to the network via Ethernet - doesn't it?

You're going to have to write some interface code - call it a "driver" if you like.

 

Again, see: http://www.8052.com/forum/read/1...

 

For support, you would need to contact the module and/or chip manufacturer.

Example codes are present in ATMEL STUDIO, but I want to write my own drivers for every peripheral, is it easy or difficult ??/

That depends on your level of skill and experience.

 

Again, the process is as described here: http://www.8052.com/forum/read/1...

 

I would doubt that interfacing a WiFi module is going to be a beginner project ...

Same answer as #2 !

Why?

 

The board already has an embedded debugger - and a USB socket for it!

 

Have you actually ready the User Manual yet?

No.

 

You need to get an Atmel-ICE or 3rd-party debug probe (eg, Segger J-Link).

Hi awneil,

I am an italian engineer with no MPUs skills, so I hope that you can help me about my trouble on using the SDRAM embeded on the SAM V71 board.

I am looking for a "ready to use" Atmel Studio 7 project for access the embeded SDRAM on my evaluation board.

I found sdram.h and sdram.c surfing on internet, but I cannot compile without error (i.e. this #include "chip.h" doesn't work, unknown type for SSdramc_Memory*p)

 

Thank you for aswering or suggestion, link or something else ...
