Starting with SAM3S

[stefano664]

Good morning,
I'm doing firsts steps with a SAM3S1B on a custom board, environment is Atmel Studio 6, ASF 3.3.

I have a problem when try to create a new solution with my micro. Step-by-step:

1) File -> New -> Project
2) C/C++ -> Userboard -> Userboard SAM3S
3) Slect the used micro (SAM3S1B)
4) Add some ASF moduls with ASF wizard (GPIO, IOPORT, PIO)
5) Add some defines in borda_conf.h (BOARD_FREQ_SLCK_XTAL, BOARD_FREQ_SLCK_BYPASS, BOARD_FREQ_MAINCK_XTAL, BOARD_FREQ_MAINCK_BYPASS)
6) Click on build solution

The compiler return this error:
Error 1 exceptions.h: No such file or directory ...\drivers\pio\pio_handler.c 44 24 USER_APPLICATION5

I've tried to manually copy exceptions.h but after that return other "file not found" errors.

Were is the mistake? Someone can help me?

Hi there!

I've recently made a custom board as well with an AT91SAM3S chip. The hardware is ready but the chip has nothing inside yet. I need to be able to code into the chip just like coding into any other commercial MCU board (e.g. arduino). I'm going to use the Atmel SAM-ICE over JTAG to interface my board to my PC.

Could you please share the steps to get started working on the software using Atmel Studio?

Thank you so much!

I had some trouble with Atmel Studio, when selecting "user board", and I found it useful to create another project, select "SAM3S-EK - ATSAM3S4C" from the Atmel-Boards list , and modify that to match my board (I use ATSAM3S4B on my board). If you still want to start off from "user board", it's still a good source of information how it was done for an Atmel board.

Also, it's a good idea to upgrade to the latest Atmel Studio, there may be bugs that cause trouble, and it's not you doing something wrong (stefano).

Anyways, if you are interested, I can share how my board looks, and what code I have. It just flashes an LED, while writing back characters on the USB that were received on the serial port.

Hi!

Thanks for replying. I've actually had quite a large progress now. It turned out to be straightforward enough . I agree that starting from a user board from scratch will give us a number of errors at the beginning (clock configuration, etc), but all of them can be worked out as far as I remember.

If you don't mind, I'm really interested to see your board and schematics I didn't implement a USB on my board, so I'd love to know how you got it to work.
