Does anyone have any info on the ATR0663? Is it still going to come out? It seems that Atmel has removed all the data on this from their website (except for...
Greatings, As a newbie to the group, I hope I'm not beating on a dead horse, but I am a little surprised by the maximum toggle rate I'm seeing on the...
I'm starting a new project using the AT91SAM7S256. My plan is to create a baseline of firmware that we will be able to build upon over several products. I am...
Hi Greg, We are currently developing a product based on the SAM7S256 and use the lib_AT91SAM7S files. They are very simple functions for performing tasks...
Hi Gene, If your achieving toggle rates around 8MHz your actually doing pretty well. The PIO module on the SAM7S is notoriously slow, its amazing how bad the...
Hi Greg, I'd definitely recommend using the include file. the macros will be quite useful. Look up the HTML pages associated with your compiler (or even look...
Thanks for confirming what I was seeing. I do agree that the SAM7S is a pretty good processor overall (DMA is a real plus, as is the sync serial, usb and...
... I thought that the Atmel ARM9 devices would also boot from NAND flash, but I guess the term "16-bit" flash does not really say NOR. I just think in terms...
Sorry to bother you with so simple questions, but I couldn't find a precise information anywhere. I need to develop an equipment with Ethernet, USART, GPIO and...
Hi Diego, For Host USB you can add a 2nd processor, such as the AT43USB380 (although it's a mature product). Atmel has the libraries to work with this chip. ...
... If you are beginning with ARM, then I don't suggest this path. The processor you are referring is a quite complex CPU, even for an experienced ARM...
If you are sure you need the AT91SAM9260 then try NutOS at: http://www.ethernut.de/en/documents/at91sam9260.html I am using it with the SAM7 and it is very...

Diego, Perhaps you could provide a little more information to help us point you in the right direction. Are you trying to develop a product to sell in large...
Hi All, I've just completed an RTOS (Sugatha) which is meant for embedded (microcontroller based) systems. Currently there's a port for the x86, AT91SAM7S and...
... Dushara, What is the advantage of your RTOS over other available RTOS? I didn't see much on the web page to explain it. I clicked on the WIKI page and...
... Hi Tick, Thanks very much for your feedback. You're right the documentation is a bit lacking..... (There is a bit but the link to it is obscure). I'm still...
... I guess no, for this case. Actually it depends on the memory requirements for the specific project. If it is considered that any application requiring a...
twgbonehead, Well, lets give you some information: The equipment: the equipment is an information reader that will be installed on a factory plant, and this...
If you try to develop all this on your own I think you will have a lot of troubles... Maybe you should look for small size PCs. Another solution is to check...
Diego, I would agree with Miroslav here. For 100 boards, you're probably a lot better off just buying your hardware (with something that includes software)....
Hello there! I haven't done anything with ARM processors up until now so I'm trying to get to know them with a AT91SAM7S-EK. My objective is to teach the ARM...
hi !, ... I'm not sure with the rest of your problem since i don't use IAR (but GCC based compiler) but i can tell you that the dbgu units it's s serial port...
... Then you need a SAM7X instead of SAM7S, don't you? When I started playing with my first ARM processor(SAM7X) one year ago, I played with IAR demos 1-2...
HI Michael, On the AT91SAM7S -EK demo boards, the DGBU (debug unit) is the right-hand serial port (DB9) connector. And then there is the USART connector on...
Thanks, Hein! I really wish the functions had better comments as to how they are to be used. Unless one can find an applciation that uses the specific...
Tnanks for the reply Alan! As I already said in another post, the naming and the functional descriptions of the functions are a bit lacking. If we are to use...
Hi, But you have a datasheet and you can find description of each register used in these functions. Each function uses only a few registers (and in most cases...
