Introduction to At91sam7x Mike Silva. You should probably also be looking at the datasheet for the board itself. Simple cheap and compact. From the Getting Started section of that:.

For example, I would like to cross compile using a toolchain I’ve already installed – arm-none-eabi a simple hello world program in C to load onto my board. How do I at91sa7x256 to the board?

I would appreciate if anyone could help me on the following aspects of the board:. Arduino Robotics Lonnie Honeycutt.

Stack Overflow works best with JavaScript enabled. Looks like your PA inputs can source as much as uA of current.

So I looked at a pretty detailed data sheet and a summary of the data sheet, but have been unsucessfull so far of finding the information I want. This question appears to be off-topic. How would I go about doing so? The only disadvantage of using the pull-down resistor to overdrive the pull-up is that you have to allow for the maximum pull-up current possible over temperature and process.

  EV ZX1I-90 PDF

I ended up using a hand full of Transistors to cover these issues properly. So a 1 kohm pull-down should do the trick.

Is it through ssh? Protecting the IoT with Invisible Keys. The users who voted to close gave this specific reason: This pulse is a flat 3,3V signal, no power up glitches or something.

If the former, which page exactly is that please? Medias this blog was made to at91sam7x25 people to easily download or read PDF files. I just recentely started working with a new board: From the Getting Started section of that: How can I therefore connect to the board datasheett I plug it in? I would appreciate if anyone could help me on the following aspects of the board: My problem is that I get a high impulse at power on of about 25ms, which is enough for the relais to a91sam7x256.

Therefor use extra transistors — they do inverting for you for proper PowerUp. Create free account Forgot password? The board is supplied “bare-metal” – no code, no OS.

There may be default firmware on the board which allows you to connect some other way, but most likely the usual way to connect while developing is via the JTAG connector.


DarkFalcon Thank you for your answer. Then the default state is for the transistor to be on and the internal pullup does not hurt. A very minor nit. You may be able at91sa7mx256 get help on Super User.

Sign in Sign in Remember me Forgot username or password? How do I load an application onto the board’s flash? The data sheet dstasheet instructions or the DVD? It seems that At91sa7x need external pulldown to compensate them I was going to ask what your drive configuration was.


Welcome to the club. It turns on both FETs and can create problems.

Adam 2 11 I would appreciate any help on this issue. There should have been a DVD with the board. If so, how is it possible to recuperate the board’s IP address. I know that the ULN is designed for 5V pegel, but 3,3V gives enough current to safely drive my relais. I have an ethernet cable for the connection. The data sheet says that this contains instructions for using the board with several different toolchains.
