This question appears to be off-topic. From at91szm7x256 Getting Started section of that: Then the default state is for the transistor to be on and the internal pullup does not hurt.

Create free account Forgot password? I know that the ULN is designed for 5V pegel, but 3,3V gives enough current to af91sam7x256 drive my relais. So a 1 kohm pull-down should do the trick. 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.

I would appreciate if anyone could help me on the following aspects of the board: This pulse is a flat 3,3V signal, no power up glitches or something. I would appreciate any help on this issue.


The only disadvantage of using the pull-down resistor to overdrive the pull-up is that you have to a9t1sam7x256 for the maximum pull-up current possible over temperature and process.

From the Getting Started section of that:. A very minor nit. DarkFalcon Thank you for your answer.

Stack Overflow works best with JavaScript enabled. How would I go xatasheet doing so? Looks like your PA inputs can source as much as uA of current.

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.

If the former, which page exactly is that please? If so, how is it possible to recuperate the board’s IP address.

AT91SAM7X256 Datasheet PDF

I ended up using a hand full of Transistors to cover these issues properly. The data sheet says that this contains instructions for using the board with several different toolchains. My problem is that I get a high impulse at power on of about 25ms, which is enough for the relais to switch. It seems that At91sa7x need external pulldown to compensate them I was going to ask what your drive configuration was.


The data sheet contains instructions or the DVD? The board is supplied “bare-metal” – no code, no OS.

Is it through ssh? Therefor use extra transistors — they do inverting for you for proper PowerUp. How dataeheet I therefore connect to the board once I plug it in? Introduction to At91sam7x Mike Silva. Medias this blog was made to help people to easily download or datashete PDF files.
